Abstract

The purpose. To study effect of moderate doses of artificial fertilizers, green manure crops and nonmerchantable produce of plant growing on productivity of 4-field grain-beet crop rotation at different systems of soil cultivation and to determine removal of nutrients crops from soil. Methods. Field, laboratory, statistical. Results. Effect of organic and mineral fertilizer systems upon productivity of cultures of short crop rotation is studied at moldboard and minimum systems of cultivation as well as indexes of removal of nutrient elements of soil. It is determined that the highest productivity of crop rotation was at organic fertilizer system on the background of moldboard system of cultivation. Conclusions. Moldboard system of soil cultivation in comparison with minimum one has ensured higher productivity of crop rotation in all alternatives of fertilizing. In particular, in alternative without fertilizing — for 37 c/hectare of f.u., in organic and mineral systems accordingly — for 43 and 30 c/hectare of f.u. Moldboard cultivation of soils resulted in higher percentage of the content and removal of nutritive matters with the yield of cultures of crop rotation.
