201857Water quality impairment through P inputs from agricultural sources is forcing promulgation of Pbased nutrient management regulations. As a result land resources existing near animal production farms will be seriously stressed. Alternate management strategies are urgently required and chemical treatment of animal manure appears capable of providing increased options.

As with all treatment scenarios solids separation increases the overall cost of handling manure. The costs and benefits of solids separation must be balanced against the overall cost and potential income of production to make sound business decisions. References APHA AWWA WEF. 1998.
