Making Canada self-sufficient in phosphorus

A proposed project near Hearst could ease this country’s reliance on imports of a diminishing commodity

The demand for increased crop production continues, placing stress on domestic consumption but also in feeding the world. That makes the search for domestic sources of phosphate as much about self-sufficiency as it is food security.

Science Notes: Phosphorus scarcity is a concern for countries with limited reserves

Researchers from the University of Maryland Center for Environmental Science have released a first-of-its-kind study quantifying cropland phosphorus budgets around the world. It is expected to help identify regional nutrient management gaps in […] Read more





Waterloo Biofilter field technician Chad Welch helped install the phosphorus removal and recovery technology and is operating the system.

More technology tested for phosphorus removal

The latest innovation will filter water at a pumping station, from tile and surface runoff

The Thames River Phosphorus Reduction Collaborative (PRC) is moving ahead with the testing of additional technologies that intercept and remove phosphorus from agricultural runoff. Phosphorus entering the system contributes to […] Read more

The lettuce pot at far right is a control. The other pots were fertilized with various mixes of commercial phosphorus fertilizer or water treatment residue and dairy wastewater mix. There is an obvious difference in biomass and leaf length between 
the control and other treatments.

Extract phosphorus derived from dairy waste water

New technology recycles disappearing essential nutrient to ensure that it doesn’t end up where it isn’t needed

Glacier FarmMedia – Researchers in Israel have developed a way to create phosphorus fertilizer from dairy farm waste water. Why it matters: If implemented on a large scale, the process […] Read more
