Laterite and lateritic soils of Andhra Pradesh are of found in patches. They were
red to dark brown, sandy clay loam to clay, moderately acidic to neutral in reaction,
non saline and high in sesquioxide (R2
O3
) contents. The soils of the study area
except for Krishnapur series (Inceptisol) were Alfisols, interpreted by presence of
illuvial-B horizons with higher base saturation. The sesquioxide content ranged from
13.77 to 30.06% in profiles and from 15.23 to 28.53% in surface samples. The lime
requirement (LR) ranged from 1.7 to 3.1 t ha-1 in profile samples and from 1.2 to 6.4
t ha-1 of CaCO3 in surface samples. There was a decrease in sesquioxide contents in
most of the profiles and decrease in LR with increasing depth in some profiles. Lower
pH directed towards higher LR. With the increase in clay content there was increase
in LR in surface soil but trend did not followed with profile soils. Sesquioxide was
not correlated significantly with LR. The DTPA extractable micronutrients like Zn,
Fe, Cu and Mn content of profile samples ranged widely from 0.121-2.120, 4.77-
41.78, 0.459-6.256 and 8.28-80.00 ppm respectively and 0.532-3.228, 12.00-75.46,
1.336-11.502 & 52.78-81.98 ppm respectively for surface samples. Significant
positive correlation existed between DTPA extractable Fe and Mn with sesquioxides
in top soils but not with profile soils
