As spring planting in Ontario is underway, questions about inputs – when, where, in what amounts and combinations – are top of mind for many growers. Nitrogen (N) applications remain a component of growing barley, oats and spring wheat, so spring cereal farmers have to consider how to use this form of nutrient management.
Joanna Follings of the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has some considerations you should keep in mind while making your nitrogen application decisions. She notes that OMAFRA’s current N guidelines are on the low side. They don’t factor in current varieties, management strategies, and the availability of plant growth regulators (PGRs). The recently announced availability of Manipulator PGR on oats and barley are another thing to consider.
The impact of inputs will differ based on your location, soil type, and other management practices, so consider these tips in the context of your farm, as always. But, if you’re looking to change up your nitrogen application or want to confirm that your typical application is agronomically supported, Follings’ report is an excellent resource.
