Abstract:
Utilization of rangelands as a pasture is one of degeneration of the over grazing from the rangelands. Overgrazing demolishes the vegetation. Consequently, the soil will be devoid of vegetation and exposed to erosion. Exclosure, is one of the simplest reformation ways on the rangelands, which causes to improve the vegetation. In order to examin the effects of the exclosure physical and chemical properties, a study has been conducted, in the area of the ancient Kohneh Lashak of Kojour, in the stance of ۶۵ Km from the south of Noshahr in theprovinceofMazandaran. In order to do so, ۲۱ samples of the soil of the two different areas of grazing and enclosure land, from the depth of ۰-۳۰ cm, were randomly-systematically, taken to the laboratory. Soil properties included: 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 package. The statistical results showed that exclousure increased organic matter, organic carbon, phosphorus and EC. Land use change decrease lime and bulk density soil and soil texture, PH, calcium, magnesium and phosphorus did not change....
