Use injection to spread slurry		Increase the degree of contact between the slurry applied and the soil		Increase the amount of ammonium-N that is bound to soil particles		Lower emissions of ammonia from slurry spreading		Lower emissions of ammonia		Maintain/improve air quality
		Decrease surface area of slurry that has been applied to land		Lower emissions of ammonia from slurry spreading		Lower emissions of ammonia		Maintain/improve air quality
