Soil Microbiology by N.S. Subba Rao is a foundational text for students and researchers in agriculture, soil science, and environmental microbiology. It is a revised edition of his earlier work, Soil Microorganisms and Plant Growth, updated to include comprehensive coverage of soil fertility and microbial activity. Key Topics Covered
The book detail the complex relationships between soil health and microbial processes:
Microbial Diversity: Detailed classification of soil microflora (bacteria, fungi, algae) and their ecological roles.
Nitrogen Fixation: Deep dives into symbiotic (Rhizobium-legume) and non-symbiotic nitrogen fixation.
Nutrient Cycling: Transformation and mineralisation of carbon, nitrogen, sulphur, and phosphorus.
Rhizosphere Interactions: Studies on the root-soil interface and microbial products that influence plant growth.
Environmental Applications: Biodegradation of pesticides and pollutants, and the use of bio-fertilizers. Accessing the Book
