Approach

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):
