Denitrification losses of nitrogen in rice can be prevented by placing ammonical fertilizers into the

A. Oxidized zone

B. Reduced zone

C. Calcified zone

D. Hydronized zone

Answer: Option B

Solution(By Examveda Team)

Nitrogen losses in any field occur mainly because of ammonia volatilization, denitrification, leaching, agricultural runoff, etc. And as in rice cultivation plantation is submerged type, ammonia based fertilizers are not recommended in flooded rice systems due to potential N loss through denitrification in the anaerobic plough layer. Denitrification losses of nitrogen in rice can be prevented by placing ammonical fertilizers into the reduced zone.
