Indian agriculture is operating at a negative balance of plant nutrients

Indian agriculture is operating at a negative balance of plant nutrients 8 - 10 mt.
The nutrient balance is defined as the difference between the nutrient inputs entering a farming system (mainly livestock manure and fertilizers) and the nutrient outputs leaving the system (the uptake of nutrients for crop and pasture production).
Nutrient balances provide information about environmental pressures. A nutrient deficit (negative value) indicates declining soil fertility.
