Collaborative project: Evaluation of the humus- and nutrient-fertilizer value of organic residues, subproject 3 (RESTorg)

Project


Project code: 22410718
Contract period: 01.02.2019 - 31.01.2022
Budget: 226,794 Euro
Purpose of research: Applied research
Keywords: organic residues, humus and fertilizer impact, biogas production, renewable ressources

The project aims at an assessment of organic residuals with special focus on digestates from biogas production regarding their impact on soil organic matter and release of plant nutrients. Therefore, methods will be developed in co-operation with the VDLUFA that allow for a standardized assessment procedure. The database for this development will consist of a number of general chemical and biological properties and results from pot and incubation experiments that will be carried out under controlled conditions as well as field experiments. Furthermore, he impact of site conditions on soil organic matter turnover and nitrogen and phosphorus release will be quantified using modelling approaches.
