Conţinutul şi formele chimice ale fierului în cernoziomurile stagnice gleice

Abstract

The paper presents data on total content and chemical forms of iron in stagnogleyic chernozems from Răut river basin in the central part of Moldova. Essential accumulation of free iron oxides is highlighted only in heavily gley horizons. The absolute majority of these compounds is presented in a crystalline form. It was shown that the genesis of stagnic chernozems is conditioned by gley compounds of Pliocene’s sedimentary rock where they were formed. The accumulation of Fe in gley horizons and particularities of humus in soils’ profile came into being as a result of a combination of contemporary and relict processes of soils’ formation.
