Yashchenko L. Agrochemical evaluation the increase sugar-beet productivity in meadow-chernozemic calcareous soil of the Forest Steppe zone of Ukraine

Object - agrochemical processes in meadow-chernozemic calcareous soil, some physiological and biochemical processes in plants of sugar beet, intensity of their passage at application of fertilizers. Methods - field, laboratory and statistical. Novelty - changes the content of a humus, nitrogen and potassium and balance of the last are established at long-time application of fertilizers, the ecological-agrochemistry estimation is carried out , efficiency of norms and ways of fertilizers application on activity of sucrosesynthesizing enzymes and sugar beet productivity is shown. Results - it is proved system of fertilizers application which provides reception of root crops productivity at a level 50 t/ha with high quality parameters and provides increase of soil fertility, positive influence foliar dressing of sugar beet on activity of sucrosesynthesizing enzymes and as result on their parameters of quality is revealed. Branch - an agriculture, agrochemistry.
