HORTICULTURE

Detailed explanation-1: -Volatilization is the loss of N through the conversion of ammonium to ammonia gas, which is released to the atmosphere. The volatilization losses increase at higher soil pH and conditions that favor evaporation (e.g. hot and windy).

Detailed explanation-2: -To be used by plants, the N2 must be transformed through a process called nitrogen fixation. Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems.

Detailed explanation-3: -What causes ammonia volatilization? The process of ammonia volatilization commonly takes place when nitrogen is in an organic form known as urea. Urea may originate from animal manure, urea fertilizers and, to a lesser degree, the decay of plant materials.
