In organic soil with plenty of oxygen, organic notrogen will be converted to NH4 + by decomposens the NH4 + will be converted to NO3 - by bacteria.

a. True

b. False

False NH₄ + is transformed first to NO₂ and then to NO₃

Explanation:

Organic nitrogen which appears in different forms like urine, dead animals or plants, Nitrogen will be converted to ammonium (NH₄+) by either fungi or bacteria, this process is called ammonification. Nitrification is the process through which ammonium (NH₄+) is transformed to nitrites (NO₂) and then into nitrates (NO₃). Each transformation is performed by different types of bacteria species.
