Role of ICT in Integrated Plant Nutrient Management System for ...

Organic Sources
Animal Dung Human Excreta, Recycling of Plant Resources and City
Wastes
Organic Sources Neither Nutrient Specific nor Concentrated Sources
For Nutritional Benefits, Organic Sources to be Decomposed
Microorganisms Engineer Their Break Down
Temperature and Moisture Conditions Influence the Decomposition
C: N ratio Decides the Time Lag for Nutrients to Become Plant Usable
Nutrient Supply from Organic Sources Remains low, Variable and
Uncertain
Second Largest Population ( About 110 crores)
Higher Number of Livestock (about 500 Millions)
Seventh Largest Geographical Area (329 Million ha)
A Vast Pool of Organic Manure for Nutrient Availability
Organic Manure Potential = 16.9 Million Tonnes of NPK
85 per cent Arises from Animal Dung, Crop Residues and Human Excreta
About 5.65 mt NPK Available for Agricultural Use
