Abstract

One of the factors of soil formation is the plant world, which accumulates organic matter through the process of photosynthesis. Organic matter is transformed into humus, which is the main dominant of the soil. In addition to humus, organic matter provides the accumulation of macronutrients such as nitrogen, phosphorus and potassium. The first priority is to create the optimal content of essential nutrients and humus in soils, along with the development of methods to improve the efficiency of fertilizer application. The results of researches of influence of various terms of sowing on change of fertility of soil and productivity of winter cultures in the conditions of the Southern Steppe of Ukraine are resulted. The balance of humus content and important macronutrients provided by winter crops during the growing season is shown. It was found that the optimal sowing period, during which winter crops form the highest yields and there is an expanded reproduction of soil fertility, occurs on October 5
