The aim of the study is to identify patterns of formation and transformation of compounds of trace elements in chornozem soils under anthropogenic load to improve of fertilizing vegetable crops to create valuable products. Methods - field-plot (phenological observations), laboratory (gravimetric, atomic emission spectroscopy, potentiometry, spectrophotometry - determination of physiological and biochemical parameters, content of macro- and microelements in plants and soil), settlement (calculation balance), mathematical and statistical (rating reliability of the data). The value of the results. The content of mobile forms of zinc and copper in chornozem of Forest-steppe of Ukraine is at insufficient level. Most of chornozem is poorly provided with mobile forms of cobalt. The content of mobile compounds of boron and manganese is at a satisfactory level. It is fixed the exceeding norms of MAC mobile form (ammonium acetate buffer solution pH 4.8) manganese in 1.3 times in the one check point at the Poltava region. Revealed, that a positive balance of trace elements is possible with application of organic fertilizers in combination with mineral fertilizing. For a positive balance in cultivation carrot is necessary to application of extra boron and molybdenum, cucumber - boron, copper, molybdenum and zinc/ It is established that the application of a out root top dressing on background organic-mineral fertilizer formed the usefulness of products with the highest content of trace elements in carrot, pea and cucumber which are growing on chornozen typical. Based on the results it is suggested fertilizer system, which improves the quality and nutritional value of vegetable products by trace elements and provides non-deficit balance of soil by major micronutrients. Areas of application - agricultural enterprises of all forms of ownership, agricultural research institutions.
