The work gives a comparative assessment of the effect of manure, green manure and combinations of them with a stubble degrader on the supply of dry biomass, accumulation of total carbon in the arable layer of meadow-chernozem soils, crop yields and quality of crop production. The current research has shown that the effect and aftereffect of oilseed radish green manure, legume green manure and oilseed radish green manure combined with a stubble degrader fallow lands have not been inferior to the manure fallow land in terms of biomass accumulation.

The article presents the research results on the effectiveness of fallow lands with green manure crops as predecessors for winter wheat in reproducing the fertility of light chestnut soils, productivity and quality of winter wheat grains in organic crop farming of the Lower Volga region. The research has shown that replacing summer fallow with a fallow with phacelia as a green manure crop increases the supply of organic matter to the soil in comparison with the control variant by 3.09 t / ha, ensures a positive balance of organic matter +4.05 t / ha.

The article presents a working model for monitoring the basic body processes in animals. The main approaches to the implementation of the proposed model are described and disclosed. It has been indicated that the requirements for assessing feed quality and actual nutritional value include the task core to be solved not only in order to control viability, but also to increase the dairy farming efficiency at agricultural enterprises of the Vologda region.

Studies on the influence of the humic-fulvate complex on the growth and development of basil plants (Ocimumbasilicum L.), and the accumulation of essential oil in the green mass have been carried out. The investigations were conducted in the fields of the experiment station of the Russian State Agrarian University - the Moscow Agricultural Academy named after K. A. Timiryazev in 2017-2018. The soil of the experimental plot was sod-podzolic, the humus content was 2.2%, total nitrogen 35.7 mg / kg, P2O5 - 235 mg / kg, potassium 180 mg / kg, pH of the aqueous extract 6.0.
