Studies on Silicate Nutrition of Rice in the Laterite Soil of Kerala I. Effect on growth and yield

Abstract

The major portion of cultivated area unerala State has laterite and lateritic types of soil which are acidic in nature and are low in productivity. When H-ion concentration exceeds a certain limit, free water soluble silica is formed. This gets leached away leaving an abundance of sesquioxide to form a soil of low productivity. The application of silicon to such soil would enhance its production potential. The problem has not been studied in great detail and the present investigation was undertaken to fill this lacuna to some extent.
