The Value of Farm Dairy Effluent

Farm dairy effluent is a valuable fertiliser and if spread onto pasture correctly will increase pasture production and reduce solid fertiliser requirements.  Other benefits include improvement in soil organic matter levels, soil structure and soil water holding capacity.
For a well managed Ecostream Effluent Irrigation System, the cost savings in fertiliser use will provide an excellent return on investment and will typically pay for the capital cost of installing the effluent system within 3-7 years.
