A low-tech, low-cost method to capture point-source ammonia emissions and their potential use as a nitrogen fertiliser

Cowan and colleagues demonstrate the feasibility of low-tech ammonia capture from manure using a water column bubbling technique, and show that dissolved calcium nitrate was effective at ammonia capture at low concentrations and near-neutral pH. This may help reduce reliance upon - and cost of - mineral fertilizer.
