ANALYSIS OF SOIL TYPES FOR ITS PHYSICO-CHEMICAL PARAMETERS AND THE SEASONAL DISTRIBUTION OF ACTINOMYCETES FROM THIRUVARUR DISTRICT, TAMIL NADU

Abstract :

The loose surface layer that covers the majority of the land is referred to as soil. The Thiruvarur district’s villages provide the soil. The area’s eight different soil types include loamy sand, clay, silty clay, saline alluvial and saline alkaline, as well as sandy clay loam, clay loam saline alluvial and silty clay alluvial. A variety of physico-chemical characteristics, including pH, temperature, moisture, loss of ignition, electrical conductivity, nitrogen, potassium, phosphorus, sulphur and hydrogen sources were examined for monsoon, post-monsoon, summer and pre monsoon seasonal soil types. Actinoplane sp, Actinomyces sp, and Micromonospora sp were discovered as a result of this inquiry. During the monsoon season, Nocardia was exclusively present.
