The objective of this paper is to propose a soil characterization methodology based on mineralogical and morphological analyses. This paper intends to offer the consequences of Powder X-ray diffraction (PXRD) exams and scanning electron microscopy-Energy dispersive X-ray spectroscopy (SEM-EDS) analyses which predict the presence of minerals in organically treated soil. PXRD offers records on the crystal shape of the pattern and different structural parameters. The observed PXRD patterns indicate the presence of Quartz, Kaolinite and Calcite. The FTIR study also confirms the variation in minerals before and after the application of the organic amendments. FTIR offers the molecular decision of mineral and natural purposeful corporations of soil. SEM exams had been extensively utilized to assess microstructural modifications within the tested specimens and examine the effects of pore size in the sandy soil. The results of SEM indicate the improvement in soil structure with a good Water Holding Capacity (WHC). EDAX studies confirm the significant variation in micronutrients. Measurement of pH and electric conductivity (EC) parameters offers valuable records for assessing soil situation for plant growth, nutrient cycling and organic hobby. It also improves the macro-nutrients like Nitrogen (N), Phosphorus( P) and Potassium (K).

FTIR analytical study has been carried out to investigate the mineralogical composition of the soil. A field experiment was carried out at Servaikaranmadam of Thoothukudi district, Tamil Nadu during Kharif season in 2018 on sandy clay loam soil to access the effect of organic manures in the soil and to determine the chemical compositions of soil samples. The experiment was laid out in Randomized Block Design (RBD) with three replications. The experiment comprised of thirteen treatment combinations. The results of the present study revealed that soils have various mineral compositions namely Quartz, Kaolinite, Montmorillonite, Feldspar and Illite etc. The application of organic manures like Goat manure (G), Vermicompost (V) and Swine manure (S) in triple manure concentration at 17 t ha-1 reveals the presence of Organic Carbon along with the minerals, before and after harvest. This ensures a better yield of black gram (Vigna Mungo L.).
