Nitrogen household during composting – balances, contents, turnover-, and release processes
Some N-compounds have a huge resource potential especially if used in agri- and horticulture culture for fertilization. On the other, N-compounds may also lead to strong negative environmental impacts. In the present book, the N-compounds as well as their behavior and changes during composting are described.
On the basis of technical scale investigations N-turn-overs and -releases were determined and N-balances generated. Based on this, universally valid principles and models were formulated considering the depend-ency on influencing factors such as substrate composition, degradation stage, water content, pH-value, tem-perature, and gas composition. The occurring processes - ammonification, nitrification, denitrification, immobilisation - are described and discussed.
The results allow the evaluation of composting in the context of the global N-household. They also can be used for the development of innovative processes, e.g. for fertilizer production from biowaste and for N-emissions minimisation strategies.
