Abstract

The silt fractions have a great impact in soil structural formation. If the soil-forming rocks do not disturb, crush, and weather, the soil-forming processes on them occur weakly, the organic substances cause the formation of the loamy stratums without completely turning. This mostly influences the initial soil-forming layers. The reproduction minerals in these soils cause initial minerals majority by occurring weakly. If these processes occur quickly, then they cause a gradual increase of the reproduction minerals and reduction of the initial minerals. The heights of the zones where the geographical spreading of such stratums is situated depend on levels.
