The impact of Improved agricultural practice (IAP) with emphasis on soil analysis based organic manure and chemical fertilizer application, replacement of 25% chemical fertilizer with Bio-fertilizers and Integrated Pest Management, was studied for 3 successive years in 5 fields in Rice- lentil – Okra cropping system in Gangetic Alluvial zones of West Bengal, India. IAP was seen to have significant beneficial effects on elevating soil organic carbon content and increase soil pH towards normality. This effect was observed to be integrated with increase in population density of some beneficial soil bacteria, like Azotobacter, Azospirillum, Rhizobium, Phosphate Solubilizing bacteria and Potash Solubilizing Bacteria. Nitrogenase activity of soil, as measured by acetylene reduction assay, was found to be enhanced after 3 years of IAP.
