Abstract

The study area was chosen in the Kifl district of Babel governorate, which is about 30 km south of the city of Hilla, the governorate center in Iraq, and its area is 49,553.04 hectares. Samples were obtained from 50 sites from the surface depth 0-30 cm. The samples were preserved and prepared from drying, milling and sifting and laboratory measurements were conducted on them. Necessary and important for the purpose of fertility evaluation, including organic matter and the percentage of N, P, K, CEC, CE, pH, CaCO3 and ESP. The fertility assessment maps and the spatial distribution map of organic matter and CEC and N, P, K have been drawn. The results showed that the soil of the study area has good fertility status and that the variety F1 occupied the largest area of the study area, the percentage of organic matter was good, the salinity was low, and the ratios of nutrients, N, P, and K were high.
