WORKING UNIT OF THE FLAT CUTTER-SUBSOILER OF FERTILIZER

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