CHERNOZEMS TYPICAL ON THE COVERING SEDIMENTS OF THE WATERSHEDS OF MOLDOVA AND THE CENTRAL RUSSIAN UPLAND: BALANCE OF MINERALS

Abstract

It is established that the composition and nature of distribution of primary and clay minerals along the profile of Moldovan and Kursk chernozems are almost identical. Mass balances of minerals in chernozems both negative. The loss of the primary minerals in the Moldovan and Kursk chernozems and close were, respectively, 740 and 815 t/ha, the loss of clay minerals, respectively 1072 and 556 t/ha. The difference in the losses of clay minerals is a result of heterogeneity of parent rocks in the Kursk chernozem, which is expressed in the gradual relief of her granulometry up the profile and the abnormal in connection with the distribution of illite in the soil profile.
