Agricultural
soils of selected regions of Southwestern Karnataka, Peninsular India, were
subjected to systematic mineralogical characterization along with the study
of soil physical properties. Physical properties such as soil texture and
micro porosity were studied using particle size analyses and positron
annihilation lifetime analysis (PALS) technique, respectively. The latter was
used to analyze micro porosity of agricultural soil. Both major and minor
minerals were identified and confirmed by some analytical techniques like
thin section study, powder X- ray diffraction, X-ray fluorescence
spectroscopy and Fourier transform infrared spectroscopy. ?
