Effluent spreading
Effluent spreading[1] is a process in which a slurry of effluent from a dairy farm's milking parlor is pumped and spread on pasture. Commonly a rotating sprinkler is used. Dairy manure contains ammonium NH4-N.
In New Zealand the application of effluent is a permitted activity, although spreading in excess is an environmental hazard.
