Studies on extractable aluminium in rice soils of Kerala

Abstract

The distribution of the various forms of aluminium in the samples of soils collected from the major rice tracts of Kerala was assessed using different extracting solutions namely ammonium acetate, potassium chloride and water. Soil characteristics like, texture, organic carbon cation exchange capacity, pH, iron and aluminium content that are likely to influence the amount of aluminium was done on two samples collected at monthly intervals, one from Velayani lake area and the other from a double crop land adjacent to the Vellayani lake.
