Corn School: Where to place fertilizer in a strip till system

Where should growers place fertilizer in strip-till strips to best protect the seed from injury while optimizing nutrient uptake?

Ontario Ministry of Agriculture, Food and Rural Affairs corn lead Ben Rosser says Ontario does have "safe rate" recommendations for in-furrow and 2"x 2" planter banding but no guidelines are currently available for strip-till fertilizer placement.

On this episode of the RealAgriculture Corn School, Rosser notes it's unlikely that there's one perfect placement. The best placement will depend on soil test values, desired rates and the grower's system.

This summer, Rosser will be working with University of Guelph soil fertility and nutrient management professor John Lauzon on a research project designed to build data to develop safe rates for strip-till fertilizer. With funding from Grain Farmers of Ontario and the Canadian Agricultural Partnership, the research team will use a custom-built 4-row strip tiller to investigate four strip placements commonly used by strip-tillers who employ shank or coulter-based strip units.
