Abstract

Reduction of soil physical stability and increasing soil susceptibility to erosion are among the most important consequences of soil quality degradation. In this study, in order to determine soil quality impact on soil physical stability, the relationships between soil quality models and two soil sustainability indices including SUSTAINABILITY INDEX (SI) and CUMULATIVE RATING (CR) in south Mashhad were evaluated. The SI and CR values had significant correlation with soil ERODIBILITY factor of the universal soil loss equation (K factor). Therefore, they were considered as indicators of erosion in the studied region. The results showed that four soil quality models including IQITDS, IQIMDS, NQITDS and NQIMDS had a significant correlation with soil sustainability indices, and the correlation coefficient of SI was higher than that of CR. Therefore, it seems that changes of soil quality could have a significant impact on soil sustainability situation. Since the SI index had high correlation with soil quality and it required less parameters than those required for determianation of CR, it was concluded that SI index can describe the soil quality changes better than CR.
