Abstract
The research was carried in soils North of Aleppo government, to determine the level of available iron existence, and finding correlation between studied Soil properties and available iron. For this purpose, 30 compound soil samples were taken from different locations in North of Aleppo government, at surface depth (0-30) cm by( ugure). to determine of chemical and physical properties that effect on availability of iron.Results of study showed that ,soil of studied locations in west of Aleppo were (loam, loam clay), pH soil was basic ,none salty, have high content of calcium carbonate, and lime Active , medium content of organic matter (0.93-3.3)% who effected on available iron (0.64-3.11)ppm. In addition to correlation were studied between chemical properties and available iron ,strong negative linear correlation was observed between available iron and (soil PH, calcium carbonate ,lime Active Reached to (r2=0.97, r2 =0.60, r2 =0.90 (respectively. which were bigger role in fixing of iron ,while was strong positive significant correlation between available iron and (Clay percentage , organic matter, CEC) Reached to (r2=0.94, r2 =0.83, r2 =0.52 (respectively.
Keywords: calcium carbonate, active lime, clay, organic matter ,available iron.
