The amount of fine dust fraction in the range of 1-5 micronsProfile of the soil ranges from 7.7% in the upper horizonumbrella to 16.0% in the soil-forming rock. In accordanceKeeping this fraction separates the upper 50 cm of the pro-Phil. Minimum fine dust observed at a depth of 30-40 cm.Composition of the mineral fraction substantiallyIt differs from that of the sludge fraction. Dominated siltyquartz and mica. The number of K-feldspar in the soil-loam binder exactly 12% (Table. 1) in the upper part of pro-Phil, particularly in the arable horizon - 21.8%. Samenature of the distribution of plagioclase, ie most of theirthe amount is fixed in the upper 50 cm thicker Profile
