- Slurry & Dirty water from 100cow herd contains 7.2 tonnes of Nitrogen
- Apply this in spring with a Splash Plate and grass will use 2.6 tonnes. Value £1,200
- Apply the same slurry at the same time with an injector and the grass will use 4 tonnes worth £1,800.
Injectors have many benefits over surface application:
- Reduced N lost to atmosphere.
- Increased spreading days – so more slurry can be spread when it’s needed.
- Increased Grazing Days – due to less contamination of the sward.
