SPECTROSCOPIC CHARACTERISATION STUDY ON ORGANICALLY AMENDED SOIL

Abstract

A spectroscopic analytical study has been carried out to investigate the mineralogical composition of the soil by amending the organic manure application. For this, a field experiment was carried out with the TKM 9 rice variety planted on sandy clay loam texture soil at Alwanneri village, Tirunelveli district, Tamil Nadu, during the Kharif season in 2020 to ascertain the effect of organic manures on the soil and to determine the chemical compositions of soil samples. The experiment was laid out in a Randomized Block Design (RBD) with three replications and thirteen treatments with three combinations of organic manure. This present work discusses the soil’s mineral compositions (i.e. Quartz, Kaolinite, Feldspar, Illite, etc.) and physical properties by varying the applications of organic manures like Farmyard manure (FYM), Vermicompost (VC) and Vegetable Waste Compost (VWC) with manure concentration at 11.5 t ha^-1 and 17.5 t ha^-1 to ensure an improved production of TKM 9 crop.
