Influence of fertilizer systems on productivity of agricultural crops in Kostroma region

The impact of fertilizer systems was evaluated on crop productivity of field crop rotation in the Kostroma region. 19.1-20.8 C/ha of feed units were collected per rotation of the field crop rotation without the use of fertilizers. The mineral fertilizer system, like the organo-mineral system, was highly efficient and provided for the collection of feed units of 26.3-28.4 C / ha, which is 37-38% higher than the control. It was more appropriate to use an organomineral system of fertilizers. Using manure at the same time as mineral fertilizers allows not only to increase productivity, but also to stabilize fertility and preserve soil biota
