In the joint project "GülleBest", emission reduction, fertiliser efficiency and practical suitability of the following application techniques for slurry and digestate in growing winter wheat and grassland stocks are evaluated:
- Spreading by trailing hose and slot technique,
- Combination of slot technique with application of a nitrification inhibitor,
- Slurry acidification and application with trailing hoses and shoes.
Investigations are carried out at different locations in comparison to the future prescribed band-shaped application to the soil surface.
The project comprises the following Work Packages (WP):
