Abstract

                                The Kothakottai series is a major soil of Sivagangai taluk. It is a medium textured, reddish brown, deep, excessively drained, neutral and in situ formed lateritic soil from weathered quartzitic gneiss. The texture is sandy loam to sandy clay loam in solum. This is relatively the coarsest textured soil of the tract. Water retentivity is meagre, frequent irrigation is needed. The hydraulic conductivity and infiltration rate are rapid. Soil and moisture conservation is the prime problem of the soil. Soil breeding and organic waste incorporation are suggested to improve the moisture retentivity.
