The objective of this study was to use some indices related to soil aggregate instead of soil erodibility factor KUSLE of the universal soil loss equation (USLE) for a calcareous soils. Twelve composite calcareous soil samples from 0 15 cm depth were collected from 12 different locations at Nineveh provenance. The selected soils were analyzed and commonly used for five erodibility indices in order to identify soil erodibility. These indices are; Clay Aggregation Index (CAI), Clay Dispersion Ratio (CDR), Clay Flocculation Index (CFI), Dispersion ratio (DR), and Erosion Index of Bouyoucos (EIB) . The results show a highly significant positive correlation (r = 0.891**) between EIB and KUSLE in comparison to the other criteria which pointed a weak correlation. Also, the results show through variance analysis that the mean of the criterion EIB values (3.651) was very close to the mean of the KUSLE values (3.839). These results mean that EIB is more reliable index for prediction the soil erodibility in calcareous soils.
