Nutrient management with organic inputs helps in building the soil heath by improving the soil microflora and amount of soil carbon, which is very important for sustainable agriculture. Protocols for organic cultivation of several crops developed along with methodologies for pests and disease (bio-agent; biopesticites) and nutrition management (bio-fertilizers). Pusa Decomposer for in situ and ex situ crop residue decomposition was developed to mitigate residue burning problems.
