Testing biowaste materials as peat replacement in organo-mineral fertilizers

open access: yesFrontiers in Sustainable Food Systems
Organo-mineral fertilizers (OMFs) can have higher efficiency than mineral fertilizers. In Europe, peat is commonly used as an organic matrix in OMFs, as it is a highly stable organic material. However, peat extraction releases long-term stored organic C.
