Next, the fertilizer application amount calculation means should fertilize in a fertilized area designated for a specific crop based on the basic reference data created by the basic reference data creation means and the fertilizer data stored in the fertilizer data storage means. The fertilizer application amount of the specific fertilizer is calculated.

Further, the total component amount calculating means calculates the total component amount of each required component from this fertilization amount, and the effective component amount calculating means multiplies the total component amount of each required component by the fertilization efficiency of each required component. The effective component amount of each required component is calculated. Thereafter, the excess / deficiency calculation means calculates the excess / deficiency of fertilization of each required component based on the effective component amount of each required component and the basic reference data of each required component.
Therefore, in the compost to be fertilized, you can know the amount of excess and deficiency of each required component, and for the insufficient component, it will be possible to supplement with chemical fertilizer separately, get accurate fertilization information, Fertilization design can be performed reliably.
In particular, considering the fertilization efficiency as an expected absorption rate for crops, it is possible to grasp the excess and deficiency of the required components of compost to be applied, especially nitrogen, phosphoric acid, and potassium. Fertilization information can be obtained and fertilization design can be performed reliably.
In addition, since the basic standard data is a numerical value that matches the actual situation of the soil, the excess / deficiency amount of fertilization of each required component calculated by the above-described excess / deficiency calculation means becomes a value more suitable for the actual situation, It becomes possible to obtain more accurate fertilization information and reliably perform fertilization design.

  In addition, if necessary, the above-mentioned effective effective ingredient amount calculating means takes into account the effective effective ingredient in consideration of at least the remaining effective amount of nitrogen among the above required ingredients that can be expected for the current year based on the amount of fertilization for the past year. A function to calculate the quantity is provided. Since the amount of effective active ingredient is calculated by taking into account the remaining effective amount of nitrogen, the numerical value becomes more accurate, and the excess and deficiency of fertilization of each required component calculated by the excess and deficiency amount calculation means more commensurate with the actual situation.

Thereby, the adjustment amount calculation means calculates at least the adjustment amount to be adjusted for potassium based on the substantial effective component amount of each required component calculated by the substantial effective component amount calculation means and the appropriate base ratio. In this case, the adjustment amount is a value that emphasizes the appropriate ratio of bases (base balance), so fertilizers that match this adjustment value are input to the field and paddy fields separately from compost, and a balanced fertilization design Can be performed. If it is excessive, the input will be postponed.
That is, the excess / deficiency calculated above is data indicating the actual condition of the soil, and fertilization may be performed according to the excess / deficiency, but this data is not necessarily good because the base balance is not considered. Although the result may not be obtained, the adjustment amount is a value that takes into account the base balance, so if fertilization is performed based on this, some components may be excessive, but the balance is good, so good results It will be easier to obtain.

  Furthermore, it is set as the structure provided with the prescription preparation means which produces the prescription which described the matter required for the corresponding soil containing the said adjustment amount as needed. You can look at the prescription and make fertilizer designs and plans, making it easier to use.

  Moreover, it is set as the structure provided with the fertilization efficiency calculating means which calculates | requires the said fertilization efficiency by a calculation based on the fertilizer data which the said fertilizer data storage means stores as needed. Since specific efficiency is obtained based on actual fertilizer data, the amount of fertilizer applied can be calculated more accurately.

  Further, if necessary, the fertilizer application amount calculation means first sets the condition of the basic reference data among the required components in the fertilizer data stored in the fertilizer data storage means with respect to the basic reference data of each required component. When the required component satisfying the condition is searched and the corresponding required component can be searched, the fertilizer application amount is determined based on the component amount of the required component that satisfies the condition. Since the required components to be satisfied are used as a reference, calculation of excess and deficiency becomes easy.

  Furthermore, if necessary, the component amount of each required component in each compost stored in the fertilizer data storage unit and used by the fertilizer application amount calculation unit is an average value of the component amounts input in the past. . Since an average value is used, a more accurate value can be obtained.

  Moreover, it is set as the structure provided with the past data transition table preparation means which produces the transition table showing the transition of the excess and deficiency of the fertilization of each required component in the past as needed. Thereby, a fertilization transition can be known and a fertilization design can be performed more reliably.

  Furthermore, it is set as the structure provided with the future prediction data calculation means which estimates and calculates the excess and deficiency of the fertilization of each required component in the future as needed. As a result, the state of fertilization after several years can be roughly grasped, and the fertilization design can be more reliably performed.

The present invention also resides in a program for fertilization information management system for causing a computer that executes the fertilization information management system to function.
The present invention also resides in a recording medium for a fertilization information management system, which is a recording medium carrying the above-described program and can be used by a computer.

According to the present invention, the amount of compost applied is calculated and the amount of excess and deficiency of each required component is calculated. Can be replenished separately using chemical fertilizers, etc., and accurate fertilization information can be obtained to ensure reliable fertilization design.
In particular, considering the fertilization efficiency as an expected absorption rate for crops, it is possible to grasp the excess and deficiency of the required components of compost to be applied, especially nitrogen, phosphoric acid, and potassium. Fertilization information can be obtained and fertilization design can be performed reliably.
In addition, when creating basic reference data for each field by correcting the reference data based on the appropriate base ratio and soil data, the basic reference data will be values that match the actual conditions of the soil. Thus, the calculated excess and deficiency of each required component becomes a numerical value more commensurate with the actual situation, so that more accurate fertilization information can be obtained and the fertilization design can be performed reliably.

  Furthermore, when calculating the adjustment amount based on the effective amount of each required component and the appropriate base ratio, the adjustment amount is a value that emphasizes the appropriate base ratio (base balance). Then, fertilizers that match this adjustment value can be input to the field and paddy fields separately from compost, and a balanced fertilization design can be performed. That is, the excess / deficiency calculated above is data indicating the actual condition of the soil, and fertilization may be performed according to the excess / deficiency, but this data is not necessarily good because the base balance is not considered. Although the result may not be obtained, the adjustment amount is a value that takes into account the base balance, so if fertilization is performed based on this, some components may be excessive, but the balance is good, so good results It will be easier to obtain.

  Hereinafter, based on an accompanying drawing, the fertilization information management system concerning an embodiment of the invention is explained in detail. As shown in FIG. 1, the fertilization information management system according to the embodiment includes a control device 1 realized by functions of a CPU and a memory of a computer, an input device 2 such as a keyboard or a mouse, a CRT, a printer, and the like. And an output device 3. And in a fertilization information management system, the program for fertilization information management systems functions. Further, a recording medium carrying this program is used as necessary.

As shown in FIG. 1, the fertilization information management system according to the embodiment includes a reference data storage unit 10, a fertilizer data storage unit 11, a fertilization efficiency data storage unit 12, and a soil data storage unit 13 in the control device 1. Yes.
The reference data storage means 10 stores reference data that defines reference amounts of at least the necessary components of nitrogen, phosphoric acid and potassium necessary for obtaining a predetermined yield per predetermined cultivation area for each of a plurality of types of crops. It is.
As the reference data, for example, as shown in FIG. 6, the local public entity can obtain the reference amount of each required component in order to obtain a predetermined yield per predetermined cultivation area (per 10 are in the figure) for each of a plurality of types of crops. The standard table (in the figure, the fertilization standard table for vegetables) is used. The reference data is input in advance from the input device 2.
When the soil data storage means 13 for storing the soil data is made to function, the reference data is corrected by the basic reference data creation means 21 described later. Further, when the soil data storage means 13 cannot be operated, the reference data is used as it is as the basic reference data.

Moreover, the fertilizer data storage means 11 stores the fertilizer data which concerns on the component amount of each required component for every several types of compost. The fertilizer data is provided from a compost supplier, or is obtained by analysis, is described in a packaging bag containing compost, or is separately described in a data sheet. Fertilizer data is input in advance from the input device 2. According to the input data, as shown in FIG. 9, the system converts the data to calculate the actual compost weight ratio (actual data) and the compost weight ratio (dry matter data) when dried, In order to easily grasp the amount, the amount is stored for each required unit (1 m ³ , 30 liters, 12 liters) and can be displayed on the output device 3.

  Moreover, the component amount of each required component in each compost stored in the fertilizer data storage unit 11 and used for calculation by the fertilizer application amount calculation unit 22 described later is an average value of the component amounts input in the past. As shown in FIG. 10, for example, the average value for the latest five times is used.

Furthermore, the fertilization efficiency data storage means 12 stores the fertilization efficiency data that defines the fertilization efficiency as the absorption ratio expected for the crop among the component amounts of each required component. In addition, the present apparatus includes fertilization efficiency calculation means 14 that calculates the fertilization efficiency by calculation based on the fertilizer data stored in the fertilizer data storage means 11.
In detail, in embodiment, as shown in FIG. 13, fertilization efficiency is shown in FIG. 12 from the input device 2 using the fertilization efficiency data published in literature etc. about phosphoric acid and potassium. It is input in advance by the fertilization efficiency input screen.
In the embodiment, the fertilization efficiency data for nitrogen is obtained by the fertilization efficiency calculating means 14 from the amount of components in the dry matter of the fertilizer data by calculation using a predetermined calculation formula. Since it calculates | requires from the actual amount of nitrogen components, it comes to be able to calculate the fertilization amount mentioned later more correctly.

Furthermore, the soil data storage means 13 includes the required component content information relating to at least the necessary components of nitrogen, phosphoric acid, and potassium in each field and the bases of at least lime, bitter soil, and potassium for each of a plurality of fields. Soil data having base information on is stored. As the soil data, data obtained by actually analyzing the soil in each field is input in advance from the input device 2 on the soil data input screen (simple soil diagnosis result) shown in FIG.
Input items include provisional specific gravity, pH, EC, CEC (cation exchange capacity), nitrogen (ammonia nitrogen, nitrate nitrogen), phosphoric acid (effective phosphoric acid), potassium (exchangeable potassium), and exchange. Lime, exchangeable mould, base saturation, potash saturation, lime saturation, mould saturation, lime / mould (me ratio), mould / potassium (me ratio). In this case, the unit of numerical values related to the necessary components of nitrogen, phosphoric acid, and potassium is generally mg / 100 g.
Note that the soil data storage means 13 for storing the soil data does not need to function in particular when the soil data is not used, and can be selected as appropriate.

In the present system, as shown in FIG. 1, in the control device 1, the item selection / designating means 20, the basic reference data creating means 21, the fertilizer application amount calculating means 22, the total component amount calculating means 23, and the effective component amount calculating means. 24, a substantial active ingredient amount calculating means 25 and an excess / deficiency amount calculating means 26 are provided.
The item selection / designating means 20 selects a specific field among a plurality of fields, a specific crop among a plurality of types of crops, and a specific compost among a plurality of types of compost, Specify the soil depth. Selection and designation are performed by the input device 2 and are selected from previously registered items or numerical values are input.

When the item selection / designation means 20 is selected and designated, the basic reference data creation means 21 is designated by the appropriate base ratio, the soil data stored by the soil data storage means 13, and the item selection / designation means 20. Based on the fertilizer application area and soil depth, the reference data stored in the reference data storage means 10 is corrected to create basic reference data for each field. The basic reference data is displayed in a “basic reference fertilizer amount” column in FIG. 17 described later.
Specifically, as basic reference data, the reference data is used as it is for nitrogen and phosphoric acid. On the other hand, for lime, bitter soil, and potassium, the appropriate base ratio (base balance), base saturation, CEC and provisional specific gravity as basic information of soil data, fertilization area specified by the item selection specifying means 20 Based on the soil depth and the like, a value calculated by a predetermined formula is used. The appropriate ratio of base is set to, for example, potash: lime: matter = 1: 5: 2. As a result, the appropriate ratio (saturation degree) of the three components in the appropriate base saturation is 1/8 for potash, 5/8 for lime, and 2/8 for bitter earth.

For example, in potassium, it is calculated by the following formula.
(Appropriate base saturation of crops x potency of potash) x CEC from soil analysis x potash equivalent x soil depth x area x provisional specific gravity by soil diagnosis ÷ 100
In the example of FIG. 17, (70/100 × 1/8) × 22 × 47 × 12 (cm) × 10 (a) × 0.8 ÷ 100≈86.9
Here, the appropriate base saturation of the crop is 70%, and the appropriate ratio (saturation) of the three components in the appropriate base saturation is 1/8 for potash, 5/8 for lime, and 2/8 for bitter earth. It is said. In addition, 1 milligram equivalent of soil base is 47 me for potash, 20 me for lime, and 28 me for bitter earth.

  The fertilizer application amount calculation means 22 is specified based on the basic reference data created by the basic reference data creation means 21 and the fertilizer data stored in the fertilizer data storage means 11 when the item selection designation means 20 is selected and designated. The fertilizer application amount of the specific type of fertilizer to be fertilized in the specified fertilization area is calculated. Specifically, the fertilizer application amount calculation means 22 first satisfies the condition of the basic reference data among the required components in the fertilizer data stored in the fertilizer data storage means 11 with respect to the calculated basic reference data of each required component. When the required component is searched and the corresponding required component can be searched, the fertilization amount is determined based on the component amount of the required component that satisfies the condition. The determined fertilizing amount is displayed on the fertilizing amount calculation table (“fertilizing amount calculation and registration”) shown in FIG. In FIG. 17, the amount of compost applied is 2,885 kg (6,700 liters).

  The total component amount calculation unit 23 calculates the total component amount of each required component among the fertilizer application amounts calculated by the fertilizer application amount calculation unit 22. The total component amount is displayed on the fertilization amount calculation table shown in FIG.

The effective component amount calculation unit 24 multiplies the total component amount of each required component calculated by the total component amount calculation unit 23 by the fertilization efficiency of each required component stored in the fertilizer data storage unit 11, and The amount of components is calculated. The effective component amount is displayed by the output device 3 in the fertilization amount calculation table ((a) in FIG. 17) shown in FIG.
In the fertilization amount calculation table, the substitution rate is calculated and displayed. The substitution rate refers to the ratio that can be substituted by the amount of the active ingredient of compost instead of chemical fertilizer with respect to the basic standard data.

As shown in the fertilization amount calculation table of FIG. 17, the real effective component amount calculation means 25 is the soil in which the soil data storage means 13 stores the effective component amount (a) of each required component calculated by the effective component amount calculation means 24. The actual effective component amount (d) of each required component is calculated by correcting based on the effective component amount (c) associated with the data. In addition, the actual effective ingredient amount calculating means 25 takes into account the remaining effective amount (b) of at least nitrogen (only nitrogen in the embodiment) among the required components that can be expected for the current year based on the amount of fertilization for the past year. Thus, it has a function of calculating the amount of the effective active ingredient. As shown in FIG. 17, the actual effective component amount is displayed in the fertilizer application amount calculation table in the output device 3.
Specifically, as shown in FIG. 17, in nitrogen, the amount of effective active ingredient (d) = effective ingredient amount (a) + residual effective ingredient (b) + soil diagnostic active ingredient quantity (c). Here, soil diagnosis active ingredient amount (c) = ammonia nitrogen (c1) + nitrate nitrogen (c2).
For phosphoric acid, potassium, lime, and bitter soil, the amount of effective active ingredient (d) = effective ingredient quantity (a) + soil diagnostic active ingredient quantity (c).

  Further, the excess / deficiency amount calculating means 26 applies fertilization of each required component based on the actual effective component amount and basic reference data (reference amount of each required component) of each required component calculated by the actual effective component amount calculating means 25. The excess / deficiency amount is calculated, and the excess / deficiency amount is displayed in the fertilization amount calculation table in the output device 3 as shown in FIG. Specifically, the excess / deficiency amount = basic reference data−actual effective component amount is calculated.

The system further includes an adjustment amount calculation unit 30. This calculates at least an adjustment amount to adjust potassium based on the actual effective component amount of each required component calculated by the actual effective component amount calculating means 25 and the appropriate base ratio.
Moreover, this system is provided with a prescription creating means 31 for creating a prescription shown in FIG. 18 in which necessary items for the corresponding soil including the adjustment amount are described.

Next, a specific calculation procedure of the adjustment amount calculation unit 30 will be described based on the description content of the prescription.
In the prescription, the above-mentioned items regarding the total number, date, soil depth, fertilization area, soil temporary specific gravity, and soil pH, which indicate the cumulative number since the prescription was registered, are displayed.
Moreover, the target value, soil diagnosis, adjustment value, and adjustment amount which will be described later are displayed for the following items.
"Inorganic Nitrogen": Ammonia nitrogen and nitrate nitrogen, and nitrogen to be mineralized in compost "Effective Phosphoric Acid": Phosphoric acid "CEC (Cation Exchange Capacity)" absorbed by crops: Soil Expresses the capacity of particles to adsorb cations such as ammonia, potassium, calcium (lime), magnesium (matter), and is expressed in milligram equivalent (me).
“Base saturation”: The percentage of soil cation exchange capacity that is filled with bases (calcium ions, magnesium ions, potassium ions). For example, in the case of Iwate Prefecture, it is 60-80% for vegetables and flower buds and 40-60% for paddy rice.
"Exchangeable lime", "Exchangeable clay", "Exchangeable potash": In the case of exchangeable lime, it means lime (calcium) that is adsorbed on the soil and easily exchanged with other cations. . The same applies to exchangeable clay and exchangeable potash.
“Lime Saturation”, “Bitter Saturation”, “Kali Saturation”: In the case of lime saturation, it indicates how much exchangeable lime is filled with the cation exchange capacity of the soil. The same applies to the bitterness saturation and potash saturation.
“Lime / bitter”, “bitter / potassium”: the ratio of residual amounts of exchangeable cations contained in soil, also referred to as base composition. It is expressed as a ratio of milligram equivalent (me). Maintaining proper base balance is very important for crop cation absorption. That is, an antagonistic action exists between the three components of lime, bitter earth, and potassium, and when one of these base components becomes excessive, absorption of the other components is suppressed.
For example, the standards presented by local governments are lime / powder of 6 or less and bitter / kali of 2 or more, but in the prescription, lime / powder is 2.5 and bitter / kali is 2 The calculation is performed so that
“Fertilization amount”: Fertilization amount calculated above

Next, the target value, soil diagnosis, adjustment value, and adjustment amount will be described in detail.
<Target value>
The target fertilization standard for each crop. For nitrogen and phosphoric acid, the values of the above reference data are used as they are. Lime, clay, and potash are calculated by a predetermined calculation formula based on the appropriate ratio (base balance) of CEC and base.
Specifically, for nitrogen and phosphoric acid, the basic fertilizer and additional fertilizer are added in the “Regional Standard Master Registration” shown in FIG. CEC is the value of “soil diagnosis result” shown in FIG. Base saturation is based on prefecture standards. According to this standard, 60% to 80% for vegetables and flower buds (use 70% for adjustment value calculation), 40% to 60% for paddy rice (50% use for adjustment value calculation), fruit tree Then, it is 60% to 80% (70% is used in the calculation of the adjustment value).

<Soil diagnosis + compost>
This is the actual effective component amount (d) calculated above and displayed in the fertilization amount calculation table shown in FIG. 17 (“effective component amount at the time of design”). For exchangeable lime, exchangeable clay, and exchangeable potash, the amount of active ingredient (kg) at the time of design is converted to mg / 100g units. The value of the base saturation is the degree of saturation with respect to the CEC of the effective component amount at the time of design. Furthermore, lime / matter and mould / potassium are represented by the equivalent ratio displayed in the fertilization amount calculation table shown in FIG.

<Adjusted value>
The adjustment value is the basic balance of “soil diagnosis + compost”, lime / matter (= 4), mould / potassium (= 1.6) is an appropriate ratio of lime / mould (= 2.5) ), The value required to adjust to bitter earth / potassium (= 2). For nitrogen and phosphoric acid, the basic standard data is adopted as it is.

<Adjustment amount>
The adjustment amount is calculated based on the excess or deficiency of “soil diagnosis + compost” and “adjustment value”. Lime, bitter earth, and potash are converted to [kg]. In the example of FIG. 18, lime, bitter earth, and potash are calculated based on the lime because the amount of “lime” in the base balance is the most excessive.

  The system further includes past data transition table creation means 32 that creates a transition table that represents the transition of excess and deficiency of fertilization of each required component in the past. The creation results are output in the tables shown in FIGS.

Further, the present system has a function of calculating the fertilization amount without causing the soil data storage means 13 to function even when soil data is not input or when soil data is input. FIG. 22 shows a fertilization amount calculation table (“basic fertilization amount calculation”) in this case. In this case, the fertilizer application amount is calculated without considering the soil data, and the reference data is used as it is as the basic reference data. Further, as shown in the fertilization amount calculation table of FIG. 22, the actual effective component amount calculation unit 25 calculates the effective component amount (a) of each required component calculated by the effective component amount calculation unit 24 and fertilization for the past year. Based on the amount, at least the remaining effective amount (b) of nitrogen (only nitrogen in the embodiment) among the required components expected for the current year is added to output the actual effective component amount (d).
That is, as shown in FIG. 22, the substantial effective component amount (d) = the effective component amount (a) + the remaining effective amount (b).

  Furthermore, in this system, when soil data is not input or when soil data is input, the soil data storage means 13 is not functioned, and the amount of fertilization of each required component in the future is estimated and calculated. Future prediction data calculation means 33 is provided. This calculation is performed in the fertilization amount calculation table ("basic fertilization amount calculation") shown in FIG. 23 by inputting the number of years elapsed (5 years in the example of FIG. 23). The remaining effective amount is calculated, and the excess / deficiency amount is calculated and displayed in the same manner as described above.

  Next, specific operations of the fertilization information management system according to the embodiment of the present invention will be described using the flowcharts shown in FIGS. The operation of this system is performed by displaying an input image or an image for displaying an output result on a display unit (not shown) such as a CRT of the output device 3 and performing an input operation such as data input by the input device 2.

<Input of reference data>
On the reference data input screen shown in FIG. 7, the reference data also shown in FIG. 4 is input (S1). The input is the crop name, target yield, nitrogen, phosphate, potassium basic fertilizer, and the amount of fertilizer applied (the total value of the basic fertilizer and top fertilizer is used as reference data) (S1). For example, as shown in FIG. 6, the reference data includes at least each of nitrogen, phosphoric acid, and potassium required for obtaining a predetermined yield per predetermined cultivation area (per 10 are in the figure) for each of a plurality of types of crops. For example, what is provided by a local government that defines the reference amount of the component is used.

<Input fertilizer data>
As shown in FIG. 8, on the screen for inputting items for each of a plurality of types of compost, the data shown in FIG. 4, that is, the compost supply destination (center name), compost name, product volume and weight data are displayed. Input (S1).
Next, as shown in FIG. 9, on the input screen (component analysis value registration and conversion table), the data shown in FIG. 4, that is, fertilizer data relating to the component amount of each required component is input for each type of compost. To do. As input, data such as moisture, nitrogen, phosphoric acid, potassium, lime, bitter earth, C / N ratio, pH, and EC for each fertilizer are input.

In this system, as shown in FIG. 10, data on the component amounts of each required component in each compost is stored for each input, and an average value of these component amounts input in the past is calculated, Data can be displayed in a list. This average value is used for calculation by the fertilizer application amount calculation means 22 described later.
Moreover, in this system, as shown in FIG. 11, in order to make it easy to grasp the amount of components for each product, it is possible to display in product volume units (1 m ³ , 30 liters, 12 liters). It has become. The display in this case is performed by converting the analysis value per dry matter into the amount per actual product (including moisture).

<Input of fertilizer efficiency>
When “Fertilization efficiency” is selected in the table shown in FIG. 9, as shown in FIG. 12, an input screen for inputting the fertilization efficiency as the absorption ratio expected for the crop out of the component amounts of each required component appears. In this input screen, fertilization efficiency data also shown in FIG. 4 is input (S1). As for the input, phosphoric acid, potassium, lime, and bitter earth are input using fertilization efficiency data published in literatures as shown in FIG. 13, for example. As for nitrogen, the fertilization efficiency data is obtained by calculation by a predetermined calculation formula from the component amount in the dry matter of the input fertilizer data by the fertilization efficiency calculation means 14 (S2 in FIG. 2) and automatically displayed. Entered.

  When the input so far is finished, as shown in FIG. 14, it can be displayed as data (compost data management) aggregated for each fertilizer. In the compost data management table, “nitrogen mineralization rate (16.24%)” is fertilization efficiency.

<Input soil data>
On the screen for inputting a plurality of fields shown in FIG. 15, the names of the fields also shown in FIG. 4 are input. Then, in the input screen (soil diagnosis result) for inputting the soil data shown in FIG. 16, the data shown in FIG. 4, that is, each required component of at least nitrogen, phosphoric acid, and potassium of the soil in each field for each of a plurality of fields. The soil data which has the base information regarding the required component content information concerning at least and the bases of at least lime, bitter soil and potassium are input. In this soil diagnosis result screen, temporary specific gravity for each soil, acidity, EC, CEC (cation exchange capacity), ammonia nitrogen, nitrate nitrogen, effective phosphoric acid, exchangeable lime, exchangeable clay, exchangeability Data such as potassium is input. In this table, the reference value is an appropriate range value presented in advance by a local government or the like.
Input data, created data, and the like are stored in the reference data storage means 10, the fertilizer data storage means 11, the fertilization efficiency data storage means 12, and the soil data storage means 13.

<Calculation of fertilizer application>
Next, the case where the fertilizer application amount is calculated will be described. The item selection specifying means 20 is caused to function by the input device 2. Specifically, the above-mentioned “soil diagnosis result” screen (FIG. 16) of the field to be calculated is displayed, and “fertilization calculation” in the screen is selected. Thereby, as shown in FIG. 17, the “fertilization amount calculation and registration” screen of the corresponding field is displayed. On this screen, the items shown in FIG. 5, that is, the name of the compost to be fertilized and the name of the crop to be cultivated are selected and input. Also input fertilizer area and soil depth. Thereby, the compost data is displayed in the table of FIG.

  When this input is performed, in the present system, the basic reference data creating means 21 corrects the inputted reference data and creates basic reference data for each field (S4). The basic reference data creating means 21 corrects the reference data based on the above soil data and creates basic reference data for each field. The basic reference data is displayed in the “basic reference fertilizer amount” column of FIG. When soil data is used, data created by the basic reference data creating means 21 is used as the basic reference data.

  When this input is made, the fertilizer application amount calculation means 22 is based on the basic reference data stored in the reference data storage means 10 and the fertilizer data stored in the fertilizer data storage means 11, and a predetermined cultivation area for a specific crop. The fertilizer application amount of a specific type of fertilizer to be fertilized at the hit is calculated (S5 in FIG. 2, FIG. 5). In this case, as shown in FIG. 3, the fertilizer application amount calculation means 22 compares the basic reference data of each required component with each required component in the fertilizer data stored in the fertilizer data storage means 11 (S11 in FIG. 3). When the required component satisfying the basic reference data is first searched for among the required components in the fertilizer data with respect to the basic reference data (S12 in FIG. 3), the corresponding required component can be searched (S13 in FIG. 3). ), Fertilization amount is determined based on the component amount of the required component that satisfies the condition (S14 in FIG. 3). In the example of FIG. 17, the basic reference data (nitrogen: 30 Kg, phosphoric acid: 30 Kg, potassium: 86.9 Kg) is a component in which phosphoric acid (content ratio 1.04%) first satisfies the conditions of the basic reference data. Therefore, the amount of compost (2,885 Kg) that makes this phosphoric acid 30 Kg is calculated. The fertilizer application amount is displayed in the table of FIG. 17 together with its capacity.

Next, the total component amount calculation unit 23 calculates the total component amount of each required component among the fertilizer application amounts of the fertilizer calculated by the fertilizer application amount calculation unit 22 (S6 in FIG. 2). The calculation result is displayed in the “total component amount” column of FIG.
Further, the effective component amount calculation means 24 multiplies the total component amount of each required component calculated by the total component amount calculation means 23 by the fertilization efficiency of each required component stored in the fertilizer data storage means 11, respectively. Is calculated (S7 in FIG. 2). The calculation result is displayed in the “active ingredient amount (a)” column of FIG.

Further, the actual effective component amount calculating unit 25 corrects the effective component amount of each required component calculated by the effective component amount calculating unit 24 based on the soil data stored in the soil data storage unit 13 to substantially increase the effective amount of each required component. The component amount is calculated (S8 in FIG. 2). In this case, the substantial active ingredient amount calculating means 25 takes into account the residual effective amount of at least nitrogen (in the embodiment, only nitrogen) among the required components that can be expected for the current year based on the amount of fertilization for the past year. The substantial active ingredient amount is calculated. The remaining effective amount is displayed in the “effective component amount (b)” column of FIG.
Specifically, for nitrogen, the amount of effective active ingredient = the amount of effective ingredient + the remaining effective amount + the effective amount of soil diagnosis (ammonia nitrogen + nitrate nitrogen), phosphoric acid, potassium, lime, and bitter soil, the effective active ingredient Amount = active ingredient amount + soil diagnostic active ingredient amount. The actual effective component amount is displayed in the “effective component amount at design (d)” column of FIG.

Then, the excess / deficiency calculation means 26 applies the fertilization of each required component based on the actual effective component amount and basic reference data (reference amount of each required component) of each required component calculated by the actual effective component amount calculation means 25. The excess / deficiency amount is calculated (S9 in FIG. 2, FIG. 5). Specifically, the excess / deficiency amount = basic reference data−actual effective component amount is calculated and displayed in the “over / deficiency amount at design” column of FIG.
Thereby, the fertilization state of the field which is going to fertilize can be grasped | ascertained clearly. In particular, since the excess and deficiency of each required component is calculated, the actual condition can be clearly understood. In addition, considering the fertilization efficiency as an expected absorption rate for crops, it is possible to grasp the excess and deficiency of the required components of compost to be applied, especially nitrogen, phosphoric acid, and potassium. Fertilization information can be obtained and fertilization design can be performed reliably.

In addition, the adjustment amount calculation means 30 is based on the actual effective component amount of each required component calculated by the actual effective ingredient amount calculation means 25 and the appropriate ratio of the predetermined bases, nitrogen, phosphoric acid, lime, bitter earth, The adjustment amount to be adjusted for potassium is calculated (S9 in FIG. 2, FIG. 5). The prescription creation means 31 creates a prescription as shown in FIG. The prescription describes items necessary for the corresponding soil including the calculated adjustment amount.
In this case, the amount of adjustment is based on “soil diagnosis + compost”, and values that place importance on CEC and base balance. Fertilizers that match this adjustment value are input to the field and paddy fields separately from compost. Therefore, a balanced fertilization design can be performed. If it is excessive, the input will be postponed.
That is, the excess / deficiency shown in FIG. 17 is data indicating the actual state of the soil, and fertilization may be performed according to the excess / deficiency, but this data is not necessarily good because the base balance is not considered. Although the results may not be obtained, the adjustment amount shown in FIG. 18 is a value that takes into account the base balance. Therefore, if fertilization is performed based on this, some components may be excessive, but the balance is good. , Good results can be easily obtained.
However, depending on the soil conditions in the field, the base saturation may exceed 200%. In such a case, a separate fertilization design is required. The adjustment amount presented by the present invention is intended for average soil having a base saturation of 200% or less, and is extremely effective for such fields.

  In addition, the present system creates a transition table showing the transition of excess and deficiency of fertilization of each required component in the past by the past data transition table creating means 32, and the results are shown in the tables shown in FIG. 19 to FIG. You can try to output. Thereby, a fertilization transition can be known and a fertilization design can be performed more reliably.

  Further, the present system has a function of calculating the fertilization amount without causing the soil data storage means 13 to function even when soil data is not input or when soil data is input. The fertilization amount calculation is performed without considering the soil data, and the reference data is used as it is as the basic reference data, and is displayed in the fertilization amount calculation table (“basic fertilization amount calculation”) shown in FIG. In addition, the actual effective component amount (effective component amount at the time of design) and the excess / deficiency amount are calculated and displayed in the same manner as described above.

  Furthermore, in this system, the future prediction data calculation means 33 does not allow the soil data storage means 13 to function even when the soil data is not input or when the soil data is input, so that the excess of fertilization of each required component in the future can be performed. The deficiency can be estimated and calculated. In the fertilization amount calculation table ("basic fertilization amount calculation") table shown in FIG. 23, when the elapsed years are input, the actual effective component amount (effective component amount at the time of design) and the excess / deficiency amount are calculated and displayed in the same manner as described above. To do. As a result, the state of fertilization after several years can be roughly grasped, and the fertilization design can be more reliably performed.
