Effects of Land Use Change on Acidity soil and Phosphorus and Calcium of Soil

ABSTRACT: The land use change is one of the important interferences of human in natural ecosystems which affect the ecosystem processes and specially the soil. Soil samples were taken using random systematic method from depth of 0 to 30 centimeters. Totally 60 soil samples (20 samples for each region) were delivered to the soil lab. The data analysis was implemented using SPSS 18 Software and in order to study and compare the data average, the one way variance analysis test and Duncan's multivariate test were used. Amount of calcium and electrical conductivity in 3 usages had no significant differences. Amount of soil acidity in forest, garden and tea garden usage have no significant differences but they had a significant difference in 95 percent significance level with pasture usage. Therefore, it can be said that land use change can affect the soil characteristics and lead to soil destruction and decline in soil nutrients. Key Terms: Land Use Change, Soil, Shenroud of Siahka
