Then during the growing season, soil microorganisms convert the ammonium to nitrate, which is the main form taken up by plants. The soil conditions most favorable to this conversion process (called ...

Nitrogen is one of the primary nutrients critical for the survival of all living organisms. Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most ...

Reaction 1 converts ammonia to the intermediate, hydroxylamine, and is catalyzed by the enzyme ammonia monooxygenase. Reaction 2 converts hydroxylamine to nitrite and is catalyzed by the enyzmer ...

Because nitrates (NO 3-) and nitrites coexist in wastewater, converting nitrite to ammonia requires significantly less energy and time compared to nitrate, optimizing overall efficiency.
