Leafy spurge outcompetes native grasses for light, water, nutrients and space, growing up to one metre tall. The weed has invaded millions of acres on the Prairies. 

Fertilizer to fight leafy spurge

Applying fertilizer could encourage soil fungi in Western Canadian pastures to become parasitic and sap resources from leafy spurge plants if the soil nutrients are rich enough —at least, that’s the idea behind recent research out of Saskatchewan

Leafy spurge is a tenacious, invasive pasture weed in Western Canada. New research suggests that fertilizer may have a role in how farmers can better beat back the threat and reclaim productivity on that grazing land.
