Status of macro and micronutrients and microbial diversity of silty clay loam soil of Thanjavur Taluk, Thanjavur District

The present study deals with the analysis of macro and micronutrients and microbial diversity of soils from Thanjavur Taluk, Thanjavur District, Tamil Nadu. Soil samples were collected at various seasons (Monsoon, Pre monsoon, Summer, Post monsoon) from three villages namely Thanjavur, Sengipatti and Sadayarkovil. The physico chemical parameters of soils were analysed. The physical parameter includes the analysis of pH, moisture content and temperature of the soils. The chemical parameter includes the analysis of macronutrients such as carbon, nitrogen, pottasium, phosphorus, calcium, magnesium and micronutrients such as zinc, iron, manganese and copper present in three crop land soils of three different villages. Totally 21 different species of soil bacteria were observed from the soil samples in three villages namely Thanjavur, Sengipatti, Sadayarkovil. Among the bacterial species identified, Staphylococcus spp, E.coli, Bacillus Spp and Entrobacter spp were dominant in bacteria. Totally 19 different species of soil fungi were observed. Among the fungal species identified, Rhizopus spp, Fusarium solani, Aspergillus spp, and Gliocladium spp were predominant in fungi. The chemical parameters and microbial population of rhizosphere soils of crop plant have suggested as future course work.
