Replication data for: Reducing short-term cover crop expense in a corn-soybean-winter wheat rotation

A common rotation in Ontario is the corn (Zea mays L.)- soybean (Glycine max L.)-winter wheat (Triticum aestivum L.) rotation. Using cover crops after winter wheat harvest could potentially benefit the rotation both environmentally and agronomically. This study helps determine whether the short-term cost of these cover crops can be negated by comparing various cover crop treatments and their potential to produce harvestable forage for additional income.

Additionally, cover crop treatments, with and without being harvested, were compared for their potential to produce a fertilizer nitrogen replacement value (FNRV) savings to the subsequent corn crop. Lastly, cover crop management strategies such as a fall manure application and different planting arrangements in cover crop mixtures were compared as a means of improving forage yield and FNRV.
