ALLUVIAL SOIL OF TERRACE FLOODPLAIN DNIESTER AND STAGNIC CHERNOZEM: NATURAL RESERVES BY POTASSIUM MINERALOGICAL INDICATORS
Abstract
It was found that in both soils immediate, proximal and potential reserves of potassium are equally high and exceed those in the zonal soils. Total reserves of potassium in them reaches 3300 mg/100 g. Big difference in the age of the soil was not reflected on the content of their total reserves of potassium. In ancient stagnic chernozem there are signs of redistribution of potassium reserves between potential and proximal likely due to clayization process. In both soils distribution of potassium reserves by the profile, in addition to direct, is determined by manifestations of layering of rocks. Propose the hypothesis that exceptionally high content of total potassium reserves in soils on alluvial sediments is their genetic traits.
