Potatoes require careful management of relatively high nitrogen (N) rates. They are a shallow-rooted crop often grown on sandy soils with potential for N leaching beyond the root zone and into groundwater. ESN has repeatedly been shown to produce greater potato yields with fewer applications, reduce N leaching, and increase grower profits.
In this mult-site, multi-year study led by researchers at the University of Manitoba, one ESN application at planting (PP) produced yields greater or similar to conventional split urea application, as well as fertigation management practice.
ESN protected N provides yield benefit and flexibility over traditional multi-pass systems.
