There are provides three levels to ensure the agriculture with industrial fertilizers. The first level (minimum) is intended for a short period, until 2015 year. Application of chemical fertilizers in minimal doses ensures maximum recovery of additional production costs. The minimum fertilization system under land degradation conditions is effective both agronomic and economic. The second (moderate) is the average (approximately 2015-2020), pointing to conservation (stabilization) the effective soil fertility. The third level (optimal) provides increasing the soil fertility and obtains the high harvests and will be implemented after the 2020 year. The optimal system of fertilization meets the requirements of maintaining economic and environmental equilibrated balance of nutrients in the soil, stabilization and reproduction of soil fertility.
