DescriptionThe results of study of groups and forms of iron compounds in leached chernozemic soils of Western Ciscaucasia for three crop rotations according to scheme grain-grass-hoeing are presented. With long-term use of leached black soil in terms of Agrigento there is a substantial change in the contents of the various groups and iron compounds. On the non-fertilized variant of rotation, the total content of this element in the 0-20 cm 21-40 cm soil layer by 69.4 and 66.5% of silicate and by 30.6% and 33.5% free group of compounds of iron. The applied system of fertilizer crop rotation helps reduce the silicate and increase of free group its compounds. In leached black soil a group of desilicated iron in the 0-20 cm layer 24.8 % presents crystallizability and to 75.2% amorphous compounds, 21-40 cm layer, respectively, 26.2 and 73,8 %. Under the influence of fertilizers we have noticed increasing of amorphous and reducing the number of cristallizing forms of the compounds of this element the soil. The number of different groups and forms of iron compounds in leached black soil with systematic use of fertilizers in crop rotation is determined not by the size of introducing this element as impurities, and processes such as the alienation of iron with additional derived products, increase its mobility in the soil due to a shift in the reaction of the soil solution, changes in fractional-group composition of humus. Diagnostic criteria state of iron in the soil are leached quantitative ratio of the content of the various groups and forms of the compounds of this element
