The Effects of Land Use Exchange on Physical and Chemical Properties in Kohneh Lashak Kojour, Nowshahr

Management activities like land cultivation will crucially affect rangeland characteristics. For sustainable utilization of rangeland to have information of these changes is needed. The aim of this research was to investigate the effect of land use exchange from range land into land farm so that soil physical and chemical properties were included. The study area is Kohne lashak 65 km from nowshahr. In order to analyse effects land use exchange on physical and chemical properties, 63 soil sampies from 0-30 cm depth were gathered and transported to laboratory. Soil properties such as; soil texture, PH, EC, bulk density , organic material, organic carbon, calcium, mg, phosphor and lime were measured in laboratory. Afterwards, data normalization and analyses of data were carried out using SPSS statistical packages. Results showed that EC, bulk density, organic matter, organic carbon, calcium, magnesium, phosphorus and lime decrease as a result of land use exchange, PH did not change by land use exchange and the changes have further changed soil texture from loam into clay loam.
