Getting soil nitrogen to growing roots cuts farm pollution
Farmers could significantly reduce agricultural emissions by getting the soil’s nitrogen-cycling processes to work together more closely, new research shows.
A new study published in Nature Communications, co-authored by researchers at the University of Reading, found that replacing synthetic fertiliser with organic sources such as manure, crop residues and biochar cut nitrous oxide emissions by an average of 21.8% and ammonia emissions by 40.6%.
