Recycling Biogas Digestate from Energy Crops: Effects on Soil Properties and Crop Productivity
Digestate from biogas production can be recycled to the soil as conditioner/fertilizer improving the environmental sustainability of the energy supply chain. In a three-year maize-triticale rotation, we investigated the short-term effects of digestate on

Casting Light on the Micro-Organisms in Digestate: Diversity and Untapped Potential
Anaerobic digestion (AD) is an established process for waste conversion to bioenergy. However, for the AD process to be viable, it is imperative that all products be adequately valorized to maximize the benefits associated with the technology and in turn

Effect of carbon-enriched digestate on the microbial soil activity.
ObjectivesAs a liquid organic fertilizer used in agriculture, digestate is rich in many nutrients (i.e. nitrogen, phosphorus, sulfur, calcium, potassium); their utilization may be however less efficient in soils poor in organic carbon (due to low carbon ...
