Workingtool for application of granulated ameliorators

The factor of preserving the fertile soil layer is most relevant on sloping lands, since streams formed by melt water and precipitation wash out nutrients and humus, and also destroy the soil surface. To prevent these processes, anti-erosion working units are used. The purpose of the research is to study the effect of soil tillage by the working unit of a flat-cutter-subsoiler of a fertilizer with the simultaneous application of granular fertilizers on its filtration properties. The work was carried out at the control site located in the Chuvash Republic. The soil is loamy. The depth of tillage and application of granular fertilizers was 30 cm. As granular fertilizers, they used - granulated manure, presented on the market and used by agricultural enterprises in crop production. The filtration coefficient, porosity, and bulk density of the soil were determined. Since the subsurface cutter tills the soil without turning the layer, samples were taken in different layers of the cut layer according to GOST R 58595–2019. The filtration coefficient, which determines the ability of the soil to absorb and pass moisture, averaged 96.2 cm per day, which can be considered a good result (for loams 20 ... 100 cm per day). The porosity was 54.3% (satisfactory condition - 50 ... 55%, excellent - 55 ... 65%), the bulk density of the soil - an average of 1.05 g/cm3 (loose or freshly plowed - 1.0 ... 1.2 g / cm3). In general, after soil cultivation by the working unit of the fertilizer subsoiler with the simultaneous application of granular fertilizers, the filtration properties of the soil correspond to generally accepted reference values.
