1. Fixation - Fixation is the first step in the process of making nitrogen usable by plants. ...
2. Nitrification - This is the process by which ammonium gets changed into nitrates by bacteria. ...
3. Assimilation - This is how plants get nitrogen. ...
4. Ammonification - This is part of the decaying process. is your answer
