Abstract
In order to investigate clayey cracks and their properties. Seven soils sites (Afak Vertic-Torrifluvent , Al-Diwaniyah Typic-Torrifluvent , Al-Taleea Typic-Torrifluvent , Babel Vertic-Torrifluvent , Agriculture college Typic-Torrifluvent , Al-Wahda Vertic-Torrifluvent and Al-Raid project Typic-Torrifluvent) were chosen for this study. The results show that EC , pH , sodium ions , organic matter , clay content , bulk density , free iron oxides (total and crystalline) , SAR and ESP were increased while CEC , moisture content , silt content , were decreased for hard part compared with friable part in all soils. The distribution of total and active carbonates were differ into two parts (hard and friable) depending on soils properties. The numbers of bacteria and fungi were decreased in hard part comparing with friable part in all soils.
