Abstract

Study on grazing effects is essential in order to finding the correct management strategies and suitable stocking rate of rangeland ecosystems. This research was carried out in order to determine GRAZING INTENSITY effects on some SOIL CHEMICAL PROPERTIES in Khabr region of KERMAN province for two years. Natural sites under three grazing pressures (heavy, moderate and none grazed) with same ecological factors were selected based on distance from water resources and nomad tents. Sampling was conducted under split plot blocked designs in two horizons (0-15 and 15-30 centimetre) and three temporal stages (before, middle and after grazing) using metal cylinder with 4 centimetre diameter. SOIL CHEMICAL PROPERTIES (PH, EC, organic matter, nitrogen content, available phosphor and potassium content) were analyzed. The results showed PH and total nitrogen contents decreased significantly on middle than before and after grazing. Organic matter was maximum on before grazing. Available phosphor content decreased 6 and 7/853 mg/kg on middle and after than before grazing, respectively. Total nitrogen, Available potassium, Available phosphorus and organic matter contents contrasting to PH decreased with increasing depth. There were not any differences in phosphor and PH contents of sites. Maximum contents of organic matters and potassium were, respectively, 1/23 % and 254/95 mg/kg in moderate grazing site, that differed to other sites. Decreasing rate of nitrogen as 18/84% was seen in heavy grazed than non-grazed site, while there wasn't significantly difference between moderate and non-grazed sites. The result showed moderate grazing immolated SOIL CHEMICAL PROPERTIES specially potassium and organic matter contents than heavy and non-grazed sites. Therefore, the moderate grazing strategy for rehabitation of Artemisia herba-alba degraded habitat is recommended.
