Efficiency of Nitrogen Fertilizers Depending on Agrichemical Properties of Chernozemic Soils in the Central Federal District of Russian Federation
The effect of the application rates of nitrogen fertilizers on yield gain in winter wheat at different agrochemical parameters of soil was statistically assessed. It was found that the correlation features (closeness, shape) in the soil-plant-fertilizer system can be used as a theoretical justification for the prediction of nitrogen fertilizer return on chernozemic soils in the Central Federal District of Russian Federation.
