Farming Phosphorus

EPISODE SUMMARY

In this episode, host Scott Beaton talks with Saskatchewan-based farmer Ian about how he manages phosphorus on his farm and the lessons learned from test plots conducted with Dr. Martin Entz at the University of Manitoba. They explore why phosphorus remains a limiting nutrient, what on-farm research is revealing, and how recycled, slow-release struvite could offer a new path for sustainable phosphorus inputs. This conversation blends practical farm experience with emerging research to highlight real solutions for phosphorus-deficient soils.

GUEST BIO

Ian and Jo-Anne Cushon, along with their son Liam, operate Moose Creek Organic Farm at Oxbow, Saskatchewan. The farm is in southeast Saskatchewan in the thin black soil zone. The primary crops grown are wheat, oats, flax, hemp, and alfalfa seed. Ian started farming in 1981 and began converting to organic farming in 1985. After 30 years of organic farming, protecting and improving the soil and managing fertility with crop rotations and off-farm inputs on 5000 acres, requires continued learning, experimentation and lots of patience.
