DYNAMICS OF DENSITY OF ADDITION AND THE GENERAL POROZITY CHERNOZEM LEACHED AT LONG AGRICULTURAL USE IN NORTHERN ZAURALYE.
Long useplowing, boardless and the differentiated plowing of soil leads to formation ofthe recondensed layers on depth of 30-40 and 60-70 sm with lowered by thegeneral porosity. Application of fertilizers over 5,0 t/he increases density of arable horizon byproductivity.
Density of soil, plowing, boardless plowing, differentiated plowing, the general porosity.
