5.2.6.4. Ammonium Nitrogen (NH + 4 - N)<br />
The evolution <strong>of</strong> the ammonium concentration <strong>of</strong> the substrate during the 3 rd<br />
composting trial follows the same pattern as the 1 st composting trial. Figure 19<br />
presents the changes <strong>of</strong> the ammonium content during the 2 nd composting trial.<br />

Figure 19: Changes in ammonium concentration [mg/kg] during the 2 nd composting trial<br />
Due to the activity <strong>of</strong> proteolytic bacteria ammonium was produced reaching a<br />
maximum <strong>of</strong> 3063.60mg/kg on the 5 th day <strong>of</strong> the process. From that point onwards the<br />
ammonium concentration was reduced significantly due to ammonia volatilization<br />
and the stimulation <strong>of</strong> nitrification and reached at 207.73mg/kg at the final day <strong>of</strong><br />
composting.<br />
