Abstract
The article presents results of the research concerning impact of mineral, organic and organic-mineral system of fertilization with different share of organic fertilizers on fertility of dark-grey podzolic soil during the period of four cycles of a short cycle cereals-growing crop rotation. It is argued that application of organic-mineral fertilization with the share of 15,0 ton/ha of organic fertilizers secures increase of the content of total humus in the soil (+ 0,24% and + 6,24 ton/ha to the indicator of the first cycle) after the fourth cycle of a short cycle field crop rotation. Mineral system of fertilization does not supply an extended reproduction of humus share in the soil (-0,06% and - 1,56 ton/ha, as compared to the similar variant of the first cycle of crop rotation). It is determined that dynamics of the content of the main elements of mineral nutrition in soil also depends on fertilization system. Under conditions of stationary field experiment the largest share of low-hydrolyzed compounds of mineral nitrogen (139 mg/kg of soil), phosphorus (113 mg/kg of soil) and potassium (109 mg/kg of soil) in one layer (0–20 cm) was secured by organic-mineral system of fertilization with the share of organic fertilizer of 15 ton/ha at the end of the fourth cycle of crop rotation. Comparing to the first cycle, the share of the main nutrition elements in the variant increased by 27,1, 36,1 and 39,7% respectively. Such system of fertilization supplied the highest level of yield of agricultural crops during the four cycles of crop rotation. However, one should note that payback of yield was reduced from a cycle to cycle in case of fertilizers application.
