Influence of diatomaceous earth and its combinations with poultry manure on soil fertility and crop productivity
The effect and aftereffect of various norms of silicon-containing agricultural ore (diatomite) on the content of humus, nutrition elements, exchange acidity, the fractional composition of water-bearing aggregates in the arable layer of gray forest soil and the productivity of corn and spring wheat were studied. Studies have found that the most significant effect on the increase in the content of humus, alkaline hydrolyzable nitrogen, mobile phosphorus and potassium, a decrease in metabolic acidity was caused by the introduction of diatomite in combination with bird droppings. It was found that the maximum increase in the total number of waterbearing aggregates in the arable layer of gray forest soil against the background of the action and aftereffect of diatomite in combination with bird droppings is mainly due to an increase in the number of water-bearing aggregates ranging in size from 1.0 to 0.25 mm. The highest effect on the productivity of corn and spring wheat was provided by the complex use of diatomite with bird droppings. The productivity of corn against their background increased by 47.7-59.6 %, the productivity of spring wheat by 26.8-35.4 %

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.
