Abstract

Air dryness and deficiency of moisture are In the wide range of Iran rangelands but with some soil mechanical operations can be increased moisture in certain areas of the pasture. In this study the effect of storing operation of curved pit and its dimensions on developing vegetation and soil of pastures was studied in Reihan plain of Ravar-Kerman province. For this purpose, sampling was done in a random way from a small, medium and a large curved pit and a region between two pits. And in each plot was measured crest cover percentage production and the number of plant bases were defined. we put ten soil profiles and sampling was done from the first 30 cm of soil surface in each area . We analyzed data by using two way ANOVA and Duncan test by SPSS21 software. The results suggested that density, production and vegetation percentage were significantly different in the four study sites (p < 0.05) The largest canpy cover and production was in the large curved pit. According to the uniformity index, the Simpson and Wilson homogeneity index has had a significant difference, based on the Simpson index and the Wilson index the highest evenness is in small curved pit. Soil analyzing results show that the organic matter and organic carbon of the large curved pit soil has had a significant increase. In general, due to the high sensitivity of rangeland ecosystems in arid and semi-arid regions we can increase the vegetation cover, by curved pit in large dimensions
