Renewable P sources: P use efficiency of digestate, processed animal manure, compost, biochar and struvite

Science of The Total Environment, 2021
In the attempt to close nutrient cycles, organic fertilizers and soil improvers are getting interest as renewable P sources for crops. However, both the P availability of these compounds for crops and the underlying mechanisms are not fully understood. In this study composts (n = 8), biochars (n = 5), animal manure and processed animal manure (n = 13),

Biogas digestates affect crop P uptake and soil microbial community composition

Science of The Total Environment, 2016
Fermentation residues from biogas production are known as valuable organic fertilisers. This study deals with the effect of cattle slurry, co-digested cattle slurry, co-digested energy crops and mineral fertilisers on the activity and composition of soil microbiota.

Investigations into Improving Dewaterability at a Bio‐P/Anaerobic Digestion Plant

Water Environment Research, 2016
ABSTRACT: Metropolitan Council Environmental Services has observed poorer than expected dewatering performance at its Empire Plant. This plant has both anaerobic digestion and enhanced biological phosphorus removal in its treatment train. A research program using pilot‐scale anaerobic digesters investigated potential solutions to the plant's poor ...
