Prystash I. Agrochemical estimation of the fertilization of corn in crop rotation on the meadow-chernozemic calcareous soil of the Forest-Steppe zone of Ukraine

Object - nutrient regime of meadow-chernozemic calcareous soil, corn grain yield and quality of grain under using fertilizers in crop rotation. The scientific substantiation of the way of nutrition optimization for corn plants in the important organogenesis stages using complex fertilizers. The purpose of the research is to estimate the influence of fertilization in crop rotation on the agrochemical processes in soil, zinc mobility, corn grain yield and quality of grain. To solve the question of nutrition optimization for corn plants taking into account the organogenesis stages. Methods of the research are field, laboratory experiment and statistical methods. Scientific novelty is scientific estimation of the corn plant nutrition optimization in the most important organogenesis stages using foliar dressing by complex fertilizers kristalon special, aquarin № 5 and nutribor. The basic results of the research are introduced into the proactive of the crop production. Field of application: agricultural chemistry.
