Abstract: Relevance and methods . The article deals with the impact of resource-saving systems for processing light-gray forest soil, the use of fertilizers and the biological product Stimix ® Niva on the value of root availability and yield of grain crops in the link of the spring wheat — pea — oats rotation in the Volga-Vyatka region. Results. The use of minimal tillage and No-till technology increases the average value of the root availability index of spring wheat plants of the ester variety to 59.2–59.6%. The use of straw destructors (ammonium nitrate and Stimix ® Niva) on the background of N 60 P 60 K 60 when growing peas of the Krasiviy variety using No-till technology reduces the rate of root availability (17.4 and 16.6%) compared to their separate use (27.6 and 29.7%) and the use of the background N 60 P 60 K 60 (25.2%). The lowest root security of Yakov variety of oat plants when using zero technology for its production is 30.8%. The highest yield of spring wheat was obtained in the variant with non-soil "shallow" tillage with the joint use of N 60 P 60 K 60 and ammonium nitrate as a straw destructor — 3.99 t/ha. The highest yield of peas of the variety Krasiviy was obtained where the main tillage was used by plowing with a plow with dumps with the use of ammonium nitrate as a straw destructor, both on the fertilized background N 60 P 60 K 60 (2.76 t/ha), and on not fertilized (2.70 t/ha). The highest average yield of Yakov variety of oats was obtained with the traditional system of soil treatment for it — 4.12 t/ha. The use of direct sowing technology provides the lowest yield of grain crops in the link of the crop rotation spring wheat – peas – oats: spring wheat 1.17–3.28 t/ha, peas 0.74–2.24 t/ha, oats 1.15–3.78 t/ha.
