Abstract: Subject to the winter rape area in crop rotation, the change of the sod gley light loam soil agrochemical properties among them humus composition was established. After the first Crop rotations rotation in the soil the hydrolytic acidity increased by 67,0-74,0%, base saturation degree decreased by 18,4-20,4%, exchange acidit, reduction tendency was noticed. During the increase of winter rape area in crop rotation (75%) the hydrolytic soil acidity increased essentially. After the first crop rotations rotation humus in the soil decreased by 14,0-16,0%. The smallest amount of total nitrogen was found in the crop rotation in which winter rape occupied 25% of the area (decrease by 30,0%), and the biggest amount was found where winter rape made 75% of the crop rotation area (decrease by 25,0%). The nutrient substances available for plants decreased in the soil as well, but the amount of mobile sulphur in the crop rotation with 25% of rape area increased 3,6 times and with 75%-5,0 times
