Ecological and agrochemical certification of farm land and forage landof such agriculturalenterprises as LLC «Zhyva Zemlia Potutory» in the village of Potutory, Berezhany district, Ternopil region and LLC «Krona» in the village of Zhukiv, Berezhany district, Ternopil region has been conducted. Soil has been characterized according to the content of humus, nitrogen (which is easily hydrolyzed), moving phosphorus, exchange potassium, moving type of sulphur as well as according to the soil acidity (pH and hydrolytic). The dynamics of weight indices of the main agrochemical characteristics of ashen–gray soil have been determined. It has been determined, that the indices have greater variability at the level of a separate field and it is less at the level of an enterprise. Having analyzed the indices of the agrochemical state of the soil of farm land and forage land of such agricultural enterprises as LLC «Zhyva Zemlia Potutory» in the village of Potutory, Berezhany district, Ternopil region and LLC “Krona”in the village of Zhukiv, Berezhany district, Ternopil region, is has been determined, that the soil have satisfactory agrochemical properties and are characterized by optimum conditions for growing crops and obtaining full value yields. The limiting factor is low content of nitrogen, which is easily hydrolyzed.
