Effect of liming on available nutrients and yield of paddy in the acid soils of Kuttanad

Abstract

The significance of lime application to the acid paddy soils of Kuttanad with respect to enhancing available nutrients and yield of paddy varieties was studied. Lime application apart from correction of harmful effects of acidity, increases the availability of essential nutrients and provides better conditions for their assimilation thereby resulting in enhanced yields of rice. The study has also brought out the inherent difference in the nature of acidity between Kari and Karapadom soils and in their capacity for utilisation of applied fertilizers.
