Hera O. Effect of agrotechnical measures on the draining organic soil fertility and crop rotation

Sybject of researh - the process of soil fertility and sown top-botton cereal miture and annual crop yield component formation. The purpose - to work out the effective energy-saving and environmetally safe technology of perennial grass mixture and annual crop cultivation in the crop rotation. The methods are field, geobotanical, measuring-weight, laboratory, mathematical-statistical, computational-comporative. The effect of meadow and field period duration in the crop rotation on the soil fertility, water regime of soil, organic matter mineralization and microbial processes is revealed. The optimal structure, crop alternation and mineral fertilizing system in short-term rotation are worked out what promotes the increase of economic efficiency and farming system stabilization of draining peat soils. The introduction of scientific developmental is carried out in 2009 in the state enterprise "Experimental farm of the Panfyly Experimental Station" over an area 200 ha. The field of application - the agricultural production.
