Show Notes

4R Nutrient Stewardship is becoming more practical, more detailed and more adaptable to the way growers manage nutrients across different crops and regions.

In this episode, host Lyle Cowell is joined by Dan Heaney to explore how Fertilizer Canada's updated 4R Practice Guidance has evolved and what's changed in their latest update. They discuss the addition of best management practices for sulfur and potassium, new guidance for manure, newly highlighted practices that don't align with the 4Rs and expanded recommendations across different climates and crops.

Tune in for a look at how 4R Nutrient Stewardship guidance has evolved, including newly added best management practices for all four major fertilizer nutrients, why the framework and new updates matter and how the newest guidance can help put 4R principles into practice.
