Chemical and Biological Technologies in Agriculture, 2022 Background The use of maize-legume mixed culture to produce renewable energy and fertilizers by anaerobic fermentation (AD), while respecting soil quality is a favourable approach in sustainable farming. This paper investigates how the substrate (silage)

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).

Short-Term Nitrogen Uptake of Barley from Differently Processed Biogas Digestate in Pot Experiments
Energies, 2019 The use of biogas digestate as fertilizer is limited by the farm nutrient balance. Mechanical separation and drying of digestate increases its transport worthiness as well as the economic feasibility of nutrient export. This study compares the fertilizer
