An incubation experiment was carried out at College of Agriculture, Padannakkad during 2015-2017 to examine suitable amelioration strategies for the iron and aluminium toxicity in acid sulphate soils of Kuttanad. The acid sulphate soils of Kuttanad region are having extreme soil pH and toxicity of Fe and Al can be ameliorated using amendments and hence can be made more productive. During the submergence period among the various parameters monitored, a steady increase was observed for pH, Ca and Mg of the soil. Application of phosphogypsum + ½ lime (T2) showed the highest increase in soil pH and available calcium content and was highly effective in lowering the toxic concentration of Fe and Al in the acid sulphate soils of Kuttanad.
