Bykina N. Agrochemical estimation of onions fertilization on dark gray podzolic soils of Northern Forest of Ukraine

The object of investigation - agrochemical and agrophysical processes in dark grey podzolic forest soil, some physiological and biochemical processes in plants, their changes depending on fertilization by traditional and improved technologies of onion cultivation. The aim of investigation - to study an influence of new fertilizers on the onion productivity and fertility indices of dark grey podzolic forest soil by traditional and improved technologies of cultivation. The methods of investigation - field permanent experiment, laboratory methods of investigation. The theoretical results - dynamics of agrochemical and agrophysical properties of dark grey podzolic forest soil and physiological processes of plant depending on the new fertilizers using under onion are substantiated. The practical results - recommendations for using of worm compost and "Riverm" both separately and with mineral fertilizers are carried out. The novelty - positive influence of the new fertilizers on agrochemical and agrophysical indices of dark grey podzolic soil and crop productivity is determined. The rate of inculation - in vegetable crop rotations of Northern Forest-Steppe of Ukraine. The Sphre - agriculture.
