AGROCHEMICAL EVALUATION OF SOILS UNDER HORTICULTURE ON THE SUITABILITY OF THEIR USAGE FOR THE MAIN AGRICULTURAL CROPS GROWING

This article reveals the results of research on agrochemical composition soils released from horticulture (Apple orchard) for effectiveness their usage in growing crops field crop rotation. The was conducted Gray forest central part Vinnytsia region forest-steppe Right Bank. subject is agro-ecological indicators that have been varying degrees intensity. It found used intensive nitrogen content easily hydrolyzed, exchangeable potassium and humus lower 37.1, 23.7, 2.9 %, mobile phosphorus, soil pH, metabolic calcium magnesium contrary higher 71.8, 12.8, 19.8 8.0 respectively, compared to extensive horticulture. There also a certain difference between compounds chemical metals under boron, molybdenum, cobalt iron 50.0, 32.8, 2.5 62.5 % horticultural lands. concentration sulfur ones. Characterizing heavy metals-toxicants horticulture, it should be noted cadmium, lead, copper mercury 4.0, 6.1, 9.5 6.6 zinc twice Analysis intensity showed basic plant nutrients needs replenished, taking into account need nitrogen. When converting arable land, necessary take measures maximize accumulation nitrogen, particular cultivation legumes. On these soils, not advisable immediately grow nitrogen-loving crops, such as corn, winter wheat sunflower, which high amount this element removed form an optimal harvest. practical significance they will enable them develop concrete proposals reducing contamination by restoring fertility improving quality material cereals grown exempted conditions.
