Effect of anaerobic digestion of manure before application to soil – benefits for nitrogen utilization? [PDF]
International Journal of Recycling of Organic Waste in Agriculture, 2021 Purpose Anaerobic digestion produces renewable energy, biogas, from organic residues, but also digestate, a valuable organic fertiliser. Previous studies have indicated that digestate contains ample plant available nitrogen (N), but there are also ...

Kinetic study of the stabilization of an agro-industrial digestate by adding wood fly ash
Chemical Engineering Journal Advances, 2021 The addition of wood fly ash to an agrowaste anaerobic digestate has been proposed for improving the carbon to nutrient ratio of the soil organic amendment (C/N/P < 100/10/1).

Impact of Adding Anaerobic Digestate to Soil and Consequences on Crop Performance
Agronomy, 2023 Anaerobic digestate is proposed as an alternative to inorganic fertilisers, but a better understanding of how anaerobic digestates impact the soil and how plant growth is influenced is needed for wider acceptance.
