Injection is a form of incorporation time of manure. It is the application of slurry by placement in slots cut into the soil, mainly to reduce ammonia emission but also odour. The following types of injection can be distinguished:
- shallow injection: the application of liquid manure by placement in shallow, vertical slots, typically about 50mm deep, cut into the soil by a tine or disc
- deep injection: the application of liquid manure by placement in deep, vertical slots, typically about 150mm deep, cut into the soil by specially designed tines.
- sod injection: the application of liquid manure by placement in bands with a slit cut into the soil beneath the bands.
The 4-hour threshold set out by experts can be considered as the approximate time limit to distinguish immediate incorporation.
