Real questions that test this

मातीतील नायट्रोजन खत जिवाणूंद्वारे तोडल्यास ______ मुक्त होते. Nitrogen fertilizers in soils releases ______ when broken down by bacteria.

a)नायट्रोजन डायऑक्साइड (NO2) / Nitrogen dioxide (NO2)
b)नायट्रस ऑक्साइड (N2O) / Nitrous oxide (N2O)
c)नायट्रोजन ट्रायऑक्साइड (NO3) / Nitrogen trioxide (NO3)✓ Correct
d)नायट्रोजन (N2) / Nitrogen (N2)

When nitrogenous fertilizers in the soil are broken down by denitrifying bacteria, Nitrous oxide (N2O) is released, which is a potent greenhouse gas.
