Keeping phosphorous on the land and out of the water

On a farm field, phosphorus is an essential crop nutrient.

But in water bodies, too much phosphorus can cause serious problems, including increased algae growth.

Algae blooms can result in oxygen depletion, leading to fish kills, and blue-green algae can release toxins into the water.

So a project is underway to develop a field-scale tool to help farmers keep phosphorus on the land.

Called Project P, this research is funded by AAFC. The tool is being designed for conditions in eastern Canada, and Reid is working with several other AAFC research scientists in eastern Canada, as well as provincial government and university researchers in Ontario and Quebec.

The tool aims to predict fields, or parts of fields, at high risk of phosphorus (P) loss.
