Using P removal structure to treat tile drainage water

Legacy phosphorus (P) has been a buzzword among farmers and researchers concerned with the increased P loading recorded in water samples. Ongoing research has indicated that in spite of documented reductions in applied P, and the increased use of cover crops, the P loading in the water continues.

Phosphorus removal does not have a silver bullet solution, and legacy and recently applied phosphorus are to be treated differently. The current thought is that particulate P is most often contained in surface run-off. Dissolved reactive phosphorus (DRP) primarily from legacy P is contained in water coming through the tile lines. | READ MORE
