The present invention relates to a granular compost mixed with livestock manure compost and dongae flour, and a method for producing the granular compost tailored to rice.

Livestock manure compost currently distributed in the market is mixed with livestock manure and moisture control agent, stirred periodically, and then powdered compost is produced and distributed. There is no major problem with compost in powder form for use in fields, orchards, and facility cultivation areas, but when used in paddy fields, particles float on the water and flow into the water system through the trough, becoming a non-point source of agricultural pollution that contaminates water quality. In addition, in order to effectively treat livestock manure that is produced in excess of the input amount of farmland (in Jeonbuk, 2.5 times the current farmland is required), quality improvement is required so that it can be easily used in paddy fields, arboretum, and new reclaimed land. Therefore, when used in paddy fields, it is necessary to suppress the leakage of nutrients contained in the compost and to granulate the particles so that the nutrient supply can be done effectively.

If livestock manure compost is used in paddy fields based on nitrogen content, there is a risk of eutrophication of water quality due to excessive phosphoric acid input.

The present invention is an invention of making livestock manure compost using cow manure, pig manure, chicken manure, etc., and adjusting fertilizer components to be suitable for crops and granulating them by adding flour to Dongae. When manufacturing the livestock manure compost, it may be prepared by mixing any one or more of cow manure, pig manure, and chicken manure.

The livestock manure compost currently distributed in the market is mixed with livestock manure and a moisture control agent, stirred periodically, and then powdered compost is produced and distributed. There is no problem in using the powdery form in fields, orchards, and facility cultivation areas, but when used in paddy fields, particles float on the water and leak into the water system through the trough, becoming a non-point source of agricultural pollution that contaminates the water quality. In addition, in order to effectively treat livestock manure that is produced in excess of the input amount of farmland (in Jeonbuk, 2.5 times the current farmland is required), quality improvement is required so that it can be easily used in paddy fields, arboretum, and new reclaimed land. Therefore, when used in paddy fields, it is necessary to suppress the leakage of nutrients contained in the compost and to granulate the particles so that the nutrient supply can be done effectively.

In the case of general powder compost, the particle form is manufactured in powder phase, so when used in paddy fields, it floats on the water surface and the compost effect does not last long. In the case of chemical fertilizers, first fertilize before planting, and second fertilize before the ears of rice appear. In contrast, in the case of granular compost, it sinks to the bottom of the paddy field and melts slowly, so the fertilizer effect lasts relatively long. Therefore, it is sufficient to apply one fertilization at the time of planting.

In the case of general livestock manure compost, on average, nitrogen-phosphate-potassium content is 1.3% nitrogen, 3.0% phosphoric acid, and 1.7% potassium. In the present specification, all parts indicated by % are weight % unless otherwise specified. When growing rice, the proper fertilization amount of rice per 10a (are) is 9.0 kg of nitrogen, 4.5 kg of phosphoric acid, and 5.7 kg of potassium. When fertilizing the nitrogen level of the livestock manure compost with an appropriate fertilization amount during rice cultivation, phosphoric acid may be excessively input and eutrophication of water quality may occur.

The rice-customized compost disclosed in the present invention is manufactured in a granular form by mixing livestock manure compost and dongae flour. When preparing the custom compost for rice, livestock manure and dongae flour may be mixed in a ratio of 5:5 to 6:4. The Dongae and the like, added to the compost for rice, is the feces of the Dongae, etc. classified into the family Diptera, and the Dongae, etc. may be the feces of the larvae of the Dongae.

The collected food waste was dehydrated, salinity was lowered, and dried and pulverized, and then the hatched larvae were provided as feed to the larvae, reared for about 7 days, and then the larvae and the larvae were separated and collected. After fermenting the collected dongae powder for about 30 days, it can be mixed with livestock manure compost to produce granular compost.

The dongae flour may contain 45% crude protein, 32% crude fat, 6.2% crude flour, and 8.4% crude fiber, and contains essential amino acids such as arginine, methionine, and lysine. However, the present invention is not limited thereto, and may further include other compositions.

[Production of custom compost for rice]

Compost was prepared by mixing livestock manure and moisture control agent, and primary fermentation was performed in a manner that was stored. Thereafter, the compost that has undergone the primary fermentation process is stirred for secondary fermentation. Next, the mixed compost was stored for a certain period of time and fermented for the third time. The tertiary fermentation is a post-fermentation process, and the fermentation period is about 30 to 50 days. The compost that had undergone the first to third fermentations was pulverized with a grinder, and prepared in a powder form (particle size 7-8 mm). The livestock manure compost contains 22% to 28% of moisture content through a drying process. However, it is not limited to the particle size or moisture content. In an embodiment of the present invention, the livestock manure may be cow manure, pig manure, or chicken manure, but is not limited thereto. The moisture control agent may include any one or more of sawdust, rice husk, and bark, but is not limited thereto.

The livestock manure compost may have a ratio of nitrogen-phosphate-potassium of 2.1%-3.9%-5.4%. However, the present invention is not limited thereto.

A fertilizer component control agent may be mixed with the livestock manure compost. The fertilizer component control agent may be Dongae, etc. In one embodiment of the present invention, livestock manure compost: the ratio of dongae, etc. may be composed of a weight ratio of 5:5 to 6:4. However, the present invention is not limited thereto and may be composed of a different composition. The ratio of nitrogen-phosphate-potassium of the compost for customizing rice in which the livestock manure compost and the dongae manure are mixed may be 4.1%-2.9%-3.0%. However, the present invention is not limited thereto.

In another embodiment of the present invention, the fertilizer component regulator may consist of a nitrogen regulator, a phosphoric acid regulator, and a potassium regulator. The nitrogen control agent may be ammonia salt, nitrate, urea, lime nitrogen and a slow release nitrogen fertilizer. The phosphoric acid modifier may be lime superphosphate, superphosphate lime, soluble phosphorus, yongwarin, and the like. The potassium regulator may be potassium chloride, potassium sulfate, or the like. However, in case of using these chemically manufactured control agents, their use is restricted in eco-friendly agriculture (organic and pesticide-free cultivation).

In one embodiment of the present invention, by producing the custom-made compost for rice with a diameter of 4 to 6 mm, it is possible to spray through a powered fertilizer spreader.

Experimental Example 1. Manufacture of customized granular compost for livestock powder and rice powder mixed with dongae, etc.

The present invention provides a crop-customized livestock manure compost. In the case of rice, the proper ratio (weight ratio) of nitrogen-phosphate-potassium is 2: 1: 1.3. In one embodiment of the present invention, it is possible to provide a rice-customized livestock manure compost.

After preparing a custom-made compost for rice by mixing livestock manure compost and dongae-e. The comeback method is a method of measuring the degree of ripening by mechanically measuring the color change of the paddle by reacting the carbon dioxide and ammonia generated by the activity of microorganisms with the paddle in the gel state when the moisture content suitable for the immature compost is maintained. Measure the level of undercooking using the comeback method, and the result of measuring the level of undercooking should be measured as 'completed undercookedness'. However, the present invention is not limited thereto, and may be a 'late stage of suffocation', 'middle stage of '

Experimental Example 1-1. Soil Characteristics Investigation

Table 1 below shows the characteristics of the soil before the rice compost treatment. The soil of the soil is silt loam, and is composed of 5.5% sand, 57.9% silt, and 36.6% clay. However, it is not limited to the above example.

After the soil having the characteristics of Table 1 was separated into a first soil and a second soil so that the soil water did not mix with each other, an experiment was performed. The first soil was fertilized with inorganic fertilizer (chemical fertilizer). Mineral fertilizers were applied 3 days before transplanting the rice seedlings. The second soil was fertilized with custom-made rice compost prepared by mixing livestock manure and Dongae flour. The customized rice compost was fertilized 25 days before the rice seedlings were transplanted.

Table 2 shows the results of fertilizing the first and second soils with inorganic fertilizers and custom-made compost, respectively, as described above, and then transplanting and cultivating rice seedlings.

[D: Days after transplanting] As a result of the experiment, when 30 days had elapsed after transplanting the rice seedlings, the planting length of the experimental group was longer, the number of tillers was higher, and the leaf color was higher than that of the control group. (the higher the value of the leaf color, the greener it is). When 60 and 90 days had elapsed after transplanting the rice seedlings, the experimental group had shorter plant lengths, fewer tillers, and lower leaf color compared to the control group's rice. As shown in Table 2, the plant height, tiller number, and leaf color of the experimental group and the control group showed almost similar values. Accordingly, paddy compost exhibits an effect almost similar to that of inorganic fertilizer.

Experimental Example 1-3. Weight of rice and quality characteristics of rice according to rice compost treatment

As described above, after harvesting the rice of the control group grown by fertilizing mineral fertilizer and the rice of the experimental group grown by fertilizing paddy compost, the weight and quality of rice were measured. Table 3 is a table showing the weight and quality of rice measured as described above.

As shown in Table 3 above, the rice of the experimental group and the rice of the control group were compared. In the case of the control rice, the weight was 787 kg/10a, whereas that of the experimental group was 744 kg/10a. In addition, in the case of the control group, the weight of brown rice was 655 kg/10a and the weight of white rice was 603 kg/10a. For the experimental group, the weight of brown rice was 619 kg/10a and the weight of white rice was 569 kg/10a.

Rice quality was compared by measuring the protein content, moisture content, amylose content, and whiteness in rice. In the case of the control group, the protein content was 5.7%, the water content was 12.2%, the amylose content was 17.4%, and the whiteness was 40.7%. In comparison, in the case of the experimental group, the protein content was 5.5%, the moisture content was 12.4%, the amylose content was 17.5%, and the whiteness was 39.6%. As shown in Table 3, the weight and quality of rice of the experimental group and the control group showed almost similar values. Accordingly, custom-made rice compost has an effect almost similar to that of inorganic fertilizer.

Experimental Example 1-4. Soil Chemistry in Rice Harvesting Season by Custom Rice Compost Treatment

As described above, the soil chemistry at harvest time of the control group grown by fertilizing with mineral fertilizer and the experimental group grown by fertilizing custom-made rice compost was evaluated. Table 4 shows the soil chemistry evaluation results of the control group (inorganic fertilizer) and the experimental group (customized rice compost) in a table.

[OM (Organic matter): organic matter content, Avail. P ₂ O ₅ : Effective phosphoric acid, Avail. SiO ₂ : Effective silicic acid, TN: Total nitrogen content in soil] As shown in Table 4 above, the soil chemistry of the experimental group and the control group was evaluated.

As a result of the evaluation, the soil chemistry during the rice harvest period increased in pH, organic matter content, effective phosphoric acid (Avail. P ₂ O ₅ ), and effective silicic acid (Avail. SiO ₂ ) and exchangeable cations decreased compared to before transplanting. Through this, it can be seen that nutrients in the soil are used in a balanced way.

More specifically, the pH of the experimental group soil and the control soil was the same at 6.1, and the organic matter content (OM) was 31.7 g/kg in the experimental group and 33.1 g/kg in the control group. Effective phosphoric acid (Avail. P ₂ O ₅ ) was 33.5 mg/kg in the experimental group and 34.9 mg/kg in the control group. Effective silicic acid (Avail. SiO ₂ ) was 186.9 mg/kg in the experimental group and 191.9 mg/kg in the control group. The potassium content was 0.49 cmol _c /kg in the experimental group and 0.38 cmol _c /kg in the control group. The calcium content was 4.78 cmol _c /kg in the experimental group and 5.93 cmol _c /kg in the control group. Magnesium was 2.17 cmol _c /kg in the experimental group and 2.18 cmol _c /kg in the control group. The sodium content was the same as _{0.16 cmol c} / kg in the experimental group and the control group. The nitrogen content in the soil was 0.07% in the experimental group and 0.08% in the control group. As shown in Table 4, the soil chemistry values of the experimental group and the control group were almost the same. Accordingly, paddy compost exhibits almost similar effects to inorganic fertilizers.

First, a column with a diameter of 10 cm and a length of 50 cm ^{is filled with paddy soil at a bulk density of 1.2 Mg/m 3} , and livestock manure (powdered, granular), liquid manure, and inorganic fertilizer are treated in the upper 10 cm, respectively, and then 5 cm at all times. watered to a height. Thereafter, eluted water of 1 pore volume (390 mL) was collected at 7-day intervals, and the contents of nitrogen, phosphoric acid, and potassium were measured. In addition, effluent and fertilizer components for each soil layer were measured.

Experimental Example 2-2. T-N cumulative amount and residual nitrogen by column layer

1 shows the accumulated amount of T-N of column effluent according to compost and liquid manure treatment. As shown in Fig. 1, the amount of T-N was high in the inorganic fertilizer treatment group at 8 to 20 weeks, but after 22 weeks, the accumulated amount of the inorganic fertilizer and the compost (granular, powdery) treatment group was similar.

2 shows the nitrogen content for each column layer of the column effluent according to the compost and liquid manure treatment. As shown in FIG. 2 , the most nitrogen in the liquid manure treatment area remained in the soil, and the least nitrogen in the powder compost area remained. Nitrogen in the inorganic fertilizer plots was abundant in the layer within 10 cm, and in the granular compost plots, in the 20 cm layer.

Experimental Example 2-3. T-P accumulation and remaining effective phosphoric acid by column layer

Figure 3 shows the T-P accumulation amount of the column effluent according to the compost and liquid manure treatment. As shown in Fig. 3, T-P was eluted the most in the liquid manure treatment group, and appeared the least in the granular compost treatment group.

4 shows the effective phosphoric acid amount for each column layer of the column effluent according to the compost and liquid manure treatment. As shown in FIG. 4 , the effective phosphoric acid in the soil was the lowest in the liquid fertilizer, and the lowest in the 10 cm layer in the inorganic fertilizer sphere. The granular compost remained similar at the 10 cm and 30 cm layers.

Experimental Example 2-4. T-K cumulative amount and remaining potassium amount by column layer

As shown in FIG. 6 , the exchangeable K content was the highest in the 30 cm layer of the acetabular acetabulum, and the highest in the 20 cm and 30 cm layers by layer.

Experimental Example 3. Investigation of nitrogen mineralization of livestock manure under paddy conditions

Experimental Example 3-1. Changes in total nitrogen content due to the treatment of livestock manure in freshwater conditions

Table 7 is a table showing changes in total nitrogen content according to the treatment of livestock manure in freshwater conditions. Total nitrogen in the inorganic fertilizer treated group was 32.4~mg/kg, the granular compost treated group was 27.8~mg/kg, and the powdered compost treated group was 32.2~mg/kg.

7 shows the nitrogen mineralization rate according to the livestock manure manure treatment in freshwater conditions. In the case of the inorganic fertilizer treatment group, the nitrogen mineralization rate was 94.0% on the 4th day, the granular compost treatment group was 96.3% on the 21st day, and the powdered compost treatment group was 97.2% on the 14th day.

During fertilizer treatment, compared to granular compost, nitrogen mineralization of inorganic fertilizer proceeds faster, so the fertilizer effect spreads quickly, but the remaining nitrogen that rice cannot use becomes a source of water pollution. On the other hand, since granular compost has a slow rate of nitrogen mineralization, the fertilizer effect appears continuously for a long time.
