A possibility of intermediate crops use as the organic fertilizer in grain-flax rotation link

Abstract

The work presents the results of three years of research on the cultivation of intermediate crop crops (buckwheat, oilseed radish, white mustard, spring rape) for green manure during compaction of the crop rotation link in the north-eastern part of Belarus on sod-podzolic medium loamy soil. Under satisfactory conditions of planting and plant development, the formation and plowing of 11–22 t/ha of green mass containing 0,8–1,2 % nitrogen, 1,1–1,6 % phosphorus, 1,2– 2,2 % potassium, increases the respiration rate of the soil by 14–36 % and its biological activity according to the degree of decomposition of linen linen by 6–9 %; reduces the density of the soil in the root-forming layer by 3–10 %.
