Investigation of Some Physical Properties of Developed Soils on the Volcanic Main Material Around Erciyes Mount

For the sustainable use of soils formed on volcanic parent material, their characteristics should be determined and management measures applied accordingly. The aim this study is to determine some physical erodibility agricultural located between east Erciyes Mountain Tomarza district. A total 58 surface soil samples (0-30 cm) were taken from area. Soil analysed according widely used analysis methods. As a result research, it was that average organic matter content (0.93%), clay (12%) lime (0.87%) contents low, whereas sand (60%) high. Among consistency limits, liquid limit found 20% plastic 14%, which both considered as low levels. When erodible parameters evaluated; aggregate stability (23%) structure index (15%) while dispersion ratio (53%) According data obtained, estimated studied have high erosion tendency. Due soils, Gyttja (about 40% Organic Matter 50% Lime) can recommended an regulator. In addition, green manuring reduced tillage improve properties soils.
