and nitrification nitrogen fixation, ammonification, and nitrification nitrogen fixation, ammonification, and denitrification. A: Nitrogen fixation, Ammonification, Nitrification are the processes of nitrogen and ammonia conversion that make nitrogen absorbable by plants.
Urea is decomposed by the enzyme urease or chemically hydrolyzed into ammonia and CO 2. In the ammonification step, ammonia is converted by ammonium-oxidizing bacteria into ammonium. In a next step, ammonium is converted by nitrifying bacteria into nitrate (nitrification).The nitrogen conversion rate depends on the conditions, present in the soil for nitrifying bacteria. Nitrates can be readily absorbed by the plant and do not need to undergo any further conversion, as is the case with urea and ammonium, before plant uptake. 2  No acidification of the soil if all the nitrogen is applied as nitrate-nitrogen.
