dc.description.abstract |
Laboratory incubation experiments were conducted with acid sulphate
soils of Kerala to investigate the changes in pH exchangeable iron, manganese,
aluminium, calcium and potassium. It was noted that flooding resulted in an
increase in the soil pH and the extent of increase was determined by certain
inherent characters of the soil. The exchangeable Fe content increased and reached
a peak value in 30 days and then decreased. The amount of Fe released was
dependent on the active iron content of the soils, of submergence. As for Mn
Ac/;' and Kayal soils showed a higher release of Mn on flooding. But all the
other soils showed only very little change. The course of change of exchangeable
Mn was similar to that of Fe. The overall effect of submergence was towards
an increased availability of Ca and K. |
