In this article the results of many years researches, also the present state of fertility of agricultural land in Vinnytsia region are generalized. The dynamics of soil provision in Vinnytsia region by boron, manganese, copper and zinc is analyzed. Laboratory studies have determined that the content of microelements in the soil of the region in the last round survey hasn’t changed. Thus, according to the results of monitoring studies, the lowest content of boron was recorded at the farms of the Nemirov district - 0.55 mg/kg, and the maximum 0.70 mg/kg - in Chechelnyk district. A slightly different situation is observed in the content of manganese, where its maximum amount (18.3 mg/kg) is noted in Pishchanka district, and the minimum (16.5 mg/kg) in Kryzhopol district.

A similar situation is observed in copper and zinc content. The lowest content of the mentioned elements was recorded at farms of Kryzhopol and Tulchyn districts, severally, 0.33 and 0.57 mg/kg. The maximum values (0.43 and 0.64 mg/kg) of their content are noted in Tulchin and Yampil districts. The average regional indicator for copper content for the tenth round survey is 0.38 mg per 1 kg of soil, and 0.6 mg per kg of soil as a zinc content.
