Agriculture and Agri-Food Canada (AAFC) research shows that adding struvite to conventional phosphorus fertilizers can help Canadian farmers maintain crop yields while reducing environmental impacts.
Phosphorus, found in some fertilizers, is an essential nutrient for crop growth. It’s produced from phosphate rock with nearly 82% of global supply being used for phosphorus fertilizer production, consuming over one million tons annually. As a non-renewable resource, once all the world’s phosphate rock has been mined, no more can be produced naturally.
While it’s not time to sound alarm bells yet, the future availability of phosphate rock is why AAFC research scientists are studying how struvite can be added to conventional fertilizers to help maintain yields, reduce phosphorus losses, improve phosphorus use efficiency, and support long term sustainability.
