Goal
- Document climate impact of frequent removal of cattle deep litter.
- Quantify methane and nitrous oxide emissions directly from deep litter in barns.
- Develop Danish emission and reduction factors for use in national inventories.
- Develop practical systems for litter application and removal at farm scale.
Plan
- Measure barn emissions from deep litter under current and frequent removal practices.
- Characterize manure and bedding composition over time to identify emission drivers.
- Compile results in a database for developing and modelling emission factors.
- Prepare guidelines for farmers balancing climate mitigation, animal welfare, and practical feasibility.
Expected results
- High-quality Danish data on greenhouse gas emissions from deep litter barns.
- Reliable emission and reduction factors ready for integration into inventories.
- Practical guidelines for farmers on litter removal frequency and system design.
- Knowledge directly supporting climate policies and sustainable livestock practices.
