Question:

Helt kort hvilke nitrogen processor sker eller kan der ske i wetlands?

Author: Asger LIndberg-Nielsen



Answer:

Nitrogen processes in wetlands Volatilization = NH4 - NH3. Tends to happen at high pH (you dont want this to happen if you have fish because that means pH is to high, (but if you just want to remove nitrogen then this might be a good idea to raise pH up to 9.) This is really smart because to take the N completely ou of the system. Anammox = NO2 -> N2. (Can happen under basicly any condition) ellers er det NH4+ + NO2− → N2 Dinitrification = NO3 - N2 To do the last two you need nitrifikation. The white layer is oxygen. The nitrification in wetlands is limited by oxygen.
