Influence of manure, cover crops and combinations of them with a degrader of stubble on soil fertility and crop yields

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 maximum biomass accumulation has led to a complex effect and aftereffect of manure and legume green manure with a stubble degrader. A combined use of manure and legume green manure with a stubble degrader has had the most significant effect on the accumulation of total carbon. Manure fallow land in combination with a stubble degrader and green manure fallow lands with legume green manure in combination with a stubble degrader have had the highest effect on the yield of winter wheat and maize as well as the quality of crop production.
