Abstract
Fifty one soil samples werecallected from some wadis soil i.e.,(El Sheikh Soliman,Sidri,El-Arishia and Bodra) of AduRudeis district, which is lies between some mountain chains. These soil samples were collected to determined their physical and chemical properties and to assess their total and available contents of Fe, Mn, Zn and Cu in a fairly intanse sampling scheme.The results indicate that the texture class varies from sandy to sandy clay loam, The content of CaCO3, organic matter, soil salinity and pH value varies from 12.4 to 579 gkg-1, 6.7 to 30.2 g Kg-1,0.23 to 8.62 dSm-1 and7.6 to 9.3, respectively. The total Fe, Mn, Zn and Cu ranged from 1020 to 9000,370 to 900, 190 to 500 and 90 to 280 mgkg-1, respectively. Most wadis soils of Abu Rudeis district have their DTPA available Fe, Mn, Zn and Cu higher than the critical leveli.e.,4,1,1 and 0.2 mg kg-1, respectively. The respective correlated coefficients, indicate that available Fe, Mn, Zn and Cu showed significant positively correlated with clay (%), (silt + clay)%, CaCO3 content, pH and ECvalues and O.M content, except availableconent of (Fe and Zn), (Mn), (Zn), (Mn) and (Fe and Zn) that showed significant negatively correlationwith clay (%), CaCO3, pH and O.M values,respectively
