Description

The invention relates to agriculture, including information structures, designed to determine the dosage of introduction of organic fertilizers (OS) under the first conditions

The purpose of the invention is to increase the information and quality of use.

Fig. 1 shows a device for determining g, organic fertilizer poses, (the upper disc is not shown), the general view in Fig. 2 is the same, the lower disc is not shown, in Fig. 3 - section A-A in Fig. 1 in Fig. 4 - the upper disk figure 5 - lower disk

The device consists of the upper disk (plate) 1, the lower disk (plate) 2 and the middle disk (plate) 3 mounted on a common axis 4. The upper disk 1 is made with slots 5-7, with slot 5 to

walks to the center of the disk Nal. Slot 5 shows the type of peat fertilizers (peat-dyne peat-shaped compost TWK) on t Slot 6 — a view that is impassive about manure (cattle — pig, poultry) over Slot 7 — a type of easily decomposable peat kind (ammoniated peat , TMAJ - 1 -2) Between the slots 5 and 6 6 and 7 in the concentric circumferences are indicated the level and imaginary yields from I to 1 The rest of the ic disk is divided by concentric nozzles and radii into cells in which digital information is placed 8 - values of coefficients (K) to opi a nical chrombones (O V) depending on the moisture content of the OS, in sector 9 - the level of planted erysipelas for crops, in sector 10 - the coefficients to OJv taking into account the mechanical composition of the soils ll of introduction to the doses to the OS

The lower disk 2 is made with slots 11-13, with the slot 11 reaching the center of the disk. Above slot 1, a type of manure-free dung (peat, straw) is indicated, over slot 12 - TMK, cattle and their ratio is 1: 1, 2: 1, 3: 1, over slot 13 - two types of OS (pig and avian) and their ratio is 2: 3, 1, 3: 1, 2: 1. Sectors 14 and 15 are located between slots 1-1 and 12, 12, and 13, with the designation of the levels of planned harvests in the crop rotation. Sector 16 shows the doses of peatothophs depending on their acidity (PH), with the left column of the soil pH, on the right - the dose of peatotofs depending on the mechanical composition of the soil.

In sector 17, the coefficients (K) to the DU dose are given, taking into account the level of fertility of various soil types from chernozem to alluvial-layered.

The information of the middle disk 3 is applied on the plate from its two sides - the top 18, facing the upper disk 1, and the bottom 19, facing the lower disk 2. On the free field of the plate below is additional information in the form of tables 20 and 21, the device name is shown above The determinant of doses of the rate of application of organic fertilizers and the dimension (t / ha). On side 18 of disc 3, digital information indicating the calculated doses of OS in accordance with the level of crops and crops is placed in concentric circles, the largest diameter of which is equal to the outer diameter of the slots of the upper disc 1. In the center of the disc on side 18 there are two concentric circles divided into sectors in which the names of the crops are indicated - cabbage, winter rye, corn, fodder root crops, perennial grasses, and the smaller circumference coincides in diameter with the inner diameter, elongated slot 5. In this Blitz 20 shows data for the preparation of TMK with various types of mineral fertilizers — double superphosphate, potassium chloride, ammonium nitrate, urea, and aqueous ammonia.

On side 19 of disc 3, digital information is placed in concentric circles similarly to the opposite side; in sectors in the center of the disc, the names of crop rotations are given: steam-cultivated, twin-seed, stern, meadow-pasture, steam-grass-growing.

Table 21 shows the data and mathematical expression for d

invoices for the actual maintenance of food elements by types of OS (bespattering, manure on bedding and TMK), where A is the dose of OS that is determined by the determinant taking into account the coefficient; C - nitrogen content,% of the raw material from table 20; Cz - nitrogen content,% raw material, determined in the OS of a particular host; A - required dose of fertilizer, t / ha. The device works as follows.

The culture applied in the center of the disk 3 on the side 18 is aligned with the edge of the disk 5 of the disk 1. At the same time, the OS doses corresponding to the culture will be indicated in slot 6 and 7. The yield levels indicated between slots 5 and 6, 6 and 7 determine the doses of organic fertilizer that are viewed in slots 6 and 7.

On the disc side 19, the slot 11 of the disc 2 and the crop rotation are combined in the same way, and the application rate is determined not for the crop, but for the entire crop rotation.

The results obtained are multiplied ng correction factors (K), which are shown on disks 1 and 2. These are corrections for

5 soil fertility, texture, moisture content of the OS. When a different chemical composition of an op amp is used in a particular host, the chemical composition correction is calculated using the equation given in table 21.

0 The device allows the agronomist to quickly determine the doses given on the Shelf discs both for individual crops and for crop rotations, in field conditions.
