Kuttanad, a low lying deltaic region 0.5 to 2.2 m below mean sea level lies on the western coast of Kerala. After conducting soil survey and classification, these acid sulphate soils were evaluated qualitatively by Land Capability Classification and quantitatively by Soil Site Suitability Classification. As per Land Capability Classification, five soil series viz., Ambalapuzha, Purakkad, Thotapally, Thuravur, Kallara and Thakazhi covering a area of 13099.60 ha were grouped under the class IV sw i.e., they are fairly good cultivable land with limitations due to soil problems and excessive wetness. Except Thotapally and Thuravur, all series belonged to soil suitability sub class S2xf. While considering suitability for paddy cultivation in the region, these soils were moderately suitable for paddy cultivation with limitations due to fertility and pH. With regard to coconut cultivation, all the soil series except Thuravur were grouped under S2xf. Thuravur series belonged to S3xf. It was marginally suitable for coconut cultivation with limitations due to fertility, pH and salinity. For mango cultivation, Kallara, Thakazhi series were marginally suitable. Considering the socio-economic situations, productivity constraints and potentials, most ideal land use models are found to be rice-fish rotational farming and rice-fish-livestock integrated farming system.
