THE ROLE OF AGROCHEMICAL MEASURES IN THE STABILIZATION OF GRAIN CROP PRODUCTIVITY ON THE TERRITORY OF THE ROSTOV REGION
Abstract
The article has given the results of the monitoring of soil sufficiency in nutrients and fertilizers, which is being carried out by the agrochemical service of the Rostov region. It has been shown that fertilizers are one of the most essential factors providing stable productivity of grain crops. Availability of labile phosphorus in soil is of special importance for the territories of the Rostov region. At present the element is the second essential element, limiting grain crop productivity in the Rostov region. During the last four years there was a stable tendency of increase of the amount of the fertilized fields with winter and spring wheat, maize for grain. Primary application of phosphorus fertilizer under plowing of the previous crop and the organization of fractional nitrogen and nitrogen-phosphorus fertilizing in the spring are of special significance during the formation of the system of winter wheat fertilizing.
