Abstract
Two biolit areas were selected within different climatic conditions in northern Iraq (Kurdistan region). Four pedons located in Ibraheemawa and five pedon in Salehaga areas. The two locationswere used for rain feed crop production. The two areas was covered with a detailed soil survey . Mapping units were obtained from Al-Agidi proposed soil classification at the series level for the Iraqi alluvial & zonal soils.Nine pedons representing the most extensive dominant soil series within the two locations were selected. A complete soil characterization was made for each soil series which include, PSD, ECe, Lime, O.M, active lime, PH, C.E.C, B.S.P, and C.E. to reveal their genesis (formations & development). Characterization was made preceded by morphological studies .The results show that a great effects of climatic conditions on the status of soil development reflected by horizons type , soil thickness and type of diagnostic horizons including surface and sub surface horizons . Also the results clearly showed the effects of climatic conditions on the amount and pattern of distribution for most soil components .The studied pedons at Ibrahimawa region were more developed than those at Salehaga region due to the difference in climatic conditions.
