Development of agriculture is related to the use of mineral fertilizers which improve material well-being of agricultural cultures macro- and by microelements and gross collections of products of plant-grower all time. After bringing of mineral fertilizers the harvest of agricultural cultures is increased more than on 30%. Therefore for description of fertility of soils research workers recommend to use agricultural chemistry indexes, which are the result of compatible action of both natural factors and production activity of man. At the same time specified on possibility of the use of agricultural chemistry indexes for the estimation of level of fertility of the ground cover and estimation of fitness them for creation of the special raw material areas. There are soils in a territory river Ikva are exhausted through a failure to observe scientifically grounded crop rotations and technologies of till of soil, decline of culture of agriculture, diminishing of volumes of bringing of mineral and organic fertilizers, development of water erosion today. Possibility to conduct the estimation of not only level of fertility of the ground cover but also his fitness the requirements of the special raw material areas appears in this connection. Territory of territory river Ikva is within the limits of Brodu district of the Lviv area, Kremenecf district of the Ternopil area and Dubno and Mliniv districts of the Rivne area. Probing the agro ecological state one of important indexes there is a level of fertility of the ground cover of territory river Ikva. Reformation of the landed relations in a river Ikva results in the gradual increase of content of macronutrients, but from 1996 year the negative tendency of worsening of balance of nitrogen, phosphorus, is however kept and to potassium. For the estimation of index of fertility content of nitrogen, mobile phosphorus, and exchange potassium is an analysis. The spatial analysis of fitness of soils is carried out for creation of the special raw material areas and territories which are of the little use for growing of agricultural cultures are certain
soils, level of fertility, special raw material areas, anthropogenic loading
