Macronutrients and their associated bacterial genera in the soils of Anaimalai block in Tamil Nadu for sustainable vegetable crops cultivation

Abstract

Meticulous analysis on intertwined interaction among the soil nutrients and microbial communities brings fruitful outcomes on horticulture. This study focuses on identifying well compatible bacterial genera in enhancing soil primary macro-nutrients for sustainable vegetable crops cultivation. The biochemical tests were executed for identification of bacterial genera. Eventually, mathematical models among available NPK nutrients (Nitrogen, Phosphorus and Potassium) and identified bacterial genera were derived to determine most suited bacterial genus for nutrients inhibition. This Study reveals the present nutrient’s status of soils at Anaimalai block covering 12,424 ha of Coimbatore district in Tamil Nadu. Seven utilitarian bacterial genera were identified which inhibit the plant nutrients. Among them, Azotobacter, Arthrobacter and Achromobacter actively inhibit available NPK in the soil. Present study of correlating soil nutrients with bacterial components enriches successful conservation of biosphere through adopting these innovative technologies in horticulture.
