A.
10 - 15 mt
B.
20 - 25 mt
C.
5 - 7 mt
D.
8 - 10 mt
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
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.
