A researcher with the University of Manitoba says the management of phosphorus applications to crop land will vary according to the source of the nutrient.

The Manitoba government has imposed strict limits on phosphorus applications to reduce the risk of excess amounts ending up in waterways.

Dr. Don Flaten, a soil fertility researcher with the University of Manitoba and chair of the National Centre for Livestock and the Environment, says the source as well as rate, placement and timing of application are fundamental to managing phosphorus.
