Özet:

 


A
study of the distribution of the electric charges in the surface horizons of
two highly weathered soils Fluvaquent and Haplaquept of West Bengal, India was
made by direct measurement of adsorption of ions in the presence of varying
concentration of electrolyte. The objective of this study was to evaluate
charge properties of two highly weathered soil of India. The results show that
pH0 varies with soil according to the variation in organic carbon
and sesquioxide/allophone content. Organic carbon strongly affects the
variation of negative charge with pH, but sesquioxide/allophone is responsible
for positive charge variation. Results used the difference between the soil pH
values measured in 1M KCl and in water for estimating the point zero charge of
the soil and ΔpH values estimating the net surface charge character. Surface
charges is a function of organic carbon, clay content, composition of clay and
amount of Fe, Al and there oxides.
