Soil samples and physical size-density fractions isolated from them (silt particle size less than 1 µm, light fraction (LF) with a density of 2 g/cm 3 the residue) ordinary chernozem were studied in three contrasting variants experimental fields Kamennaya Steppe agrolandscape Voronezh region: mowed steppe, long-term permanent bare fallow corn – main differences which are tillage (cultivated not...

Field experiments were carried out in the Rostov region on slope of ordinary chernozems system contour-strip organization territory 2011-2020. The aim research was development agrotechnical methods (design crop rotation, method basic tillage and background fertilizers), which ensure high productivity rotations eroded preservation fertility. experiment included three factors: design main tillage...
