The higher water-holding capacity of Oxisols and Ultisols compared to that of the Vertisols and Inceptisols at 15 bars of suction is attributed to the presence of intra-aggregate void spaces. Existence of such voids was verified with the aid of a scanning electron microscope. These voids are obvious in soils with kaolinitic and oxidic mineralogy but are not evident in soils of montmorillonitic or amorphous oxide composition.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
