Optimization of the soil nutrient regime in the agrophytocenoses of corn

Data describing significant fertility decline has been presented on the example of the state of sodpodzolic soils of Polissya part Chernihiv region. Lack of based approaches to fertilize crops with intensive use for the cultivation of energy crops leads to soil degradation. Application of intermediate blue lupine siderates in conjunction with the recommended dose of N90P90K90 for agriculture zone may be as a way of significant increase in fertility indicators, sustainability of modern agrocenoses. Results of field experience over the corn cultivation for grain are evidence of this.
