The model shows: in the long term, replacing mineral fertilisers with digestate from biogas plants can improve soil quality and reduce greenhouse gases

Key Points

The aim is to evaluate the long-term effects of using digestate from biogas plants instead of mineral fertilizers on soil quality and greenhouse gas emissions.
Comparative analysis of soil quality measurements with digestate and mineral fertilizers
Assessment of greenhouse gas emissions from agricultural practices
Evaluation of humus formation in soils treated with digestate
Digestate application leads to improved soil quality and increased humus formation.
Greenhouse gas emissions decrease when mineral fertilizers are replaced with digestate.
Soils treated with digestate perform better as carbon dioxide sinks.

Abstract

• Fermentation residues from biogas plants are a promising alternative to mineral fertilizers. • Replacing mineral fertilizers can improve the greenhouse gas balance of agriculture. • Soils benefit from humus formation and can act as CO2 sinks.

The model shows: in the long term, replacing mineral fertilisers with digestate from biogas plants can improve soil quality and reduce greenhouse gases
