Abstract
The article describes the importance of using micronutrients in the dry climate of the Southern Steppe of Ukraine on degraded soils under conditions of atmospheric pollution, violation of traditional schemes of crop rotation of crops and deficiency of organic fertilizers. The main purpose of the study, taking into account that the fertilization was carried out in a single scheme, both in terms of norms and technology, was to investigate the influence of soil ecological factors on the yield of winter wheat against the background of differentiation of the extracorporeal fertilization with the trace elements of Reakom (Zn, Cu, B, Mo, Co, P 2 O 5 , K 2 O) in a dose of 2.5 l/ha and 5 l/ha. The research was carried out on chernozem in the usual low-humus and its eroded abnormalities: weak and medium-sized, which marked the rise of carbonates due to some blurring of the upper accumulative genetic horizon and deterioration of qualitative soil fertility indices. The yield of winter wheat on chernozem was almost 1.17% higher than that of 2.5 l/ha, compared to control, whereas there was no effect on the washed offs. For application of 5l/ha Reakom at discarded crop yields increased to 13.8% on medium-chernozem. Effectiveness of the drug for foliar application of winter wheat in arid conditions on the abovementioned soil abnormalities is described by the regression equation, the use of which will allow the efficient allocation of funds when planning purchases of trace elements of trace elements.
