Assessment of total maximum daily load implementation strategies for nitrate impairment of the Raccoon River, Iowa.

abstract：:Water quality concerns and revised regulations are changing how confined animal feeding operations manage manure. Devising acceptable and feasible changes in manure practices requires a full understanding of the forces shaping current manure management decisions. Previous theoretical models have shown that a wide rang...
