| Abstract | ||
| After identification of the species’ site in Shazand, Arak, samples of aerial parts and litter were collected randomly and systematically in the known sites at the end of the growing season (summer) so that for analyzing the features of these species, 10 plots were installed along 4 transects. After data gathering, they were analyzed by the independent T. test and the variance analysis test. The Comparison of the aerial parts and the litter in the range species, analyzed in this study, showed that there was a signification difference between OM, C & ADF ratios in the aerial parts and the litter of these species. Quantitatively, the amount of N, C, OM, P, C/N in the litter was more than the aerial parts, whereas, the amount of k in the aerial parts was more than the litter. As a whole, in Astragalus ammodendron, the ratio of C to N was the least among the other species, so the quality of its litter, aerial parts, and soil amendment was much better. | ||
