A scientific paper by Lærke Wester Larsen, Dorette Sophie Müller-Stöver, Tapio Salo and Lars Stoumann Jensen about the risk of ammonia (NH3) volatilization from 39 biobased fertilizers (BBFs) was just published in the Journal of Environmental Management of Science Direct.
The key findings of the authors are that the potential NH3 volatilization varies substantially among BBFs. The highest NH3 volatilization potential was found from digestates and the lowest NH3 volatilization potential from composts and struvites. The NH3 volatilization potential from BBFs could effectively be reduced by incorporating the BBFs into soil, and the soil type had a great impact on the potential NH3 volatilization from the BBFs.
