‘Closing the Loop’ with Recycled High-Phosphorus Organic Fertilizers

Originally shared by Organic Science Research Cluster 4 on November 7, 2025.

Watch ‘Closing the Loop’ with Recycled High-Phosphorus Organic Fertilizers, a film in OSC4’s documentary series, Captured on Film: Organic Science in the Making. 

Dr. Joanne Thiessen Martens, University of Manitoba, and Dr. Henry Wilson, AAFC – Brandon, are exploring the potential for developing high-phosphorus organic fertilizers by co-composting nutrient-rich organic materials like yard waste and food waste with P-rich mineral waste products like struvite. Find out how their research on recycled inputs could benefit both crop agronomy and the environment. 

All films in the series will be available for streaming on the Organic Federation of Canada’s YouTube playlist Captured on Film: Organic Science in the Making.
