The aeration of buffalo slurry reduces Soil GHGs emissions and improves spinach plant growth

The aeration process promotes a reduction in the ammonia content (the substrate for nitrification) in slurry which mitigates N2O emission from soil. The pre-treated slurry results a good fertiliser as it improves the plant growth and reduces the heavy metals content in edible parts of spinach plant. The overall data show that the aerobic treatment of slurry subjected to 24 hours of air insufflating might represent a valid strategy to recycle animal wastes and utilize it as fertilizer.
