Slurry Injection

Practice: Inject slurry into soil

This practice is the placement of manure slurry (manure of 8% to 15% solids) beneath the soil surface with a minimum of mixing or stirring of the soil. Injection of slurry will reduce ammonia emissions, odor, and the potential for flies. The nitrogen value of the slurry will be 15% to 40% greater than if the manure was not incorporated. The application rate of slurry should not exceed the nutrient management plan recommendation.
