Influence of ecological fertilizer systems on the fertility of gray forest soil and winter wheat yield

Goal. To study the influence of ecological fertilizer systems (EFS) on physicochemical, agrochemical, and biochemical indicators gray forest soil’s fertility winter wheat yield. Methods. Field — to determine impact EFS properties soil; laboratory establish quantitative qualitative characteristics soil environment; comparative compare yield levels wheat; mathematical-statistical substantiate probability results. Results. Peculiarities formation physicochemical parameters under conditions are generalized. Against background pea straw (block I) contributed alkalization (pH (KCl)) by 0.25–0.29 units relative control, which significantly increased content Ca2+ Mg2+ 12–32%, control. N60P90K90 II) with addition humus (HF) or manure aftereffects reduced negative effect acidification caused use stabilization in it. HF application aftereffect improved nutrient regime, a mobile water-soluble organic matter, decomposition linen fabric 37–49% compared The based ensured at level 3.96–4.28 t/ha. In combination HF, was range 5.31–5.42 Conclusions. Under growing soil, rates have crop yields increased, especially case application: + N30P45K45 biostimulator, N60R90K90 BS aftereffect.
