Interrelation of Agrometeorological Conditions, Turf-Podzolic Soil Fertility and Field Experience Crops Productivity

Field experiments depend on the individual contribution of each of the studied factors affecting crop yields. Therefore, it is important to determine the agrometeorological conditions, individual indicators of soil fertility influence on the grain-row crop rotation crops productivity. The object of research is crops of grain-row crop rotation of the Center for Precision Agriculture (CPA) of the Russian State Agricultural Academy named after K.A. Timiryazev, Moscow. Research methods are generally accepted for this kind of research. The research purpose is to determine the participation of the main weather conditions and soil fertility indicators in the formation of the corresponding crop yield of the grain-row crop rotation. The influence of meteorological indicators of the growing season has been established, and therefore the research years are divided into appropriate groups of favorable, average and unfavorable years. As a result, their separate effects on the agrophysical, biological and agrochemical properties of the soil were noted, and the basic tillage techniques influence on the field crops yield was also established. Over the 14-year period of the CPA experience existence, it was found that the yield of the vetch-oat mixture for feed for dump processing is higher than zero by 2.0 t/ha, winter wheat – by 0.3 t/ ha. Potatoes formed a yield for plowing by 2.3 t/ha more than for minimum processing. Barley provided the same productivity according to the options of dump and minimum soil treatments. Each of the authors takes participation in field surveys carrying out and observations. In accordance with the obtained results, it becomes possible to predict the possibility of obtaining a particular productivity based on the analyzed factors and conditions with a sufficient degree of probability.
