Influence of forage crop rotations on crop yields and phytosanitary conditions of soils in the Baikal region

摘要

The article considers the practical aspects of ensuring the preservation of natural ecosystems based on the use of organic farming technologies. It presents the results of research in the forest-steppe zone of the Baikal region for 2011-2018. On the basis of the phytosanitary state of crops studying analysis, it was found that the correct alternation of crops in crop rotation suppresses the level of weeds, thereby not affecting the productivity of agricultural crops. The paper reveals the characteristics of agrophysical and water properties of gray forest soil, the influence of forage crop rotations with meadow clover on the yield of cultivated crops. According to the research results, the authors found that overseeding of legumes in the fields of forage crop rotations increases the average productivity by 16.6% in comparison with the control option. The influence of the aftereffect of perennial legumes in crop rotations increases the yield of grain fodder and silage crops by 20-31.8%. The crop rotation with two fields of meadow clover (crop rotation No. 3) was determined to be the best for all indicators.
