BROWN FOREST SOILS OF MOLDOVA'S CODRY: BALANCE OF MINERALS
Abstract
Comparative balance of minerals in brown forest soils of Moldova's Codri and xerophytic forest chernozems showed similar in size losses in both soil types of primary minerals and 2-3-fold increase in the loss of clay minerals in the former. Total losses of silicates in the brown forest soils by the profile are 12-20 kg/100 kg of breed. Weathering of minerals in these soils is influenced by acid decomposition and proceeds as podzolization without signs of lessivage and subsurface clayization of horizons B.
