What if corn, like soybeans, could fix its own nitrogen? It’s a question agronomist Dale Cowan and his team at AGRIS Co-operative are tackling this summer as they test a biological product that promises to help corn plants fix nitrogen, when applied directly on the seed, in pop-up fertilizer, and through foliar application between the… Read More

Weather is the ultimate source for small talk, and rainfall is perhaps the most talked about — from how much, to when, to not enough, and on too much. For this episode of the Corn School, Bernard Tobin asks Dale Cowan, senior agronomist at AGRIS C0-operative, about how much rain a corn crop needs throughout… Read More

Proper staging is critical when applying in-crop herbicides in corn, but there are multiple ways to measure corn’s growth stages, and herbicide labels don’t always use the same method. Agronomists often use the “leaf collar” — or V-stage — method to describe growth stages, while others use plant height. However, herbicide labels often refer to… Read More

Early-season corn scouting requires a little bit of time and attention, but can really pay off for the rest of the year and even into the next. Sara Meidlinger, market development specialist with Pride Seeds for Western Canada, joins Kara Oosterhuis for this Corn School episode. Scout representative areas of the field including good and… Read More

Dry spring planting conditions have many growers wondering how their soil-applied residual herbicides will perform, as the weather continues to heat up with little meaningful rain in sight. Research by University of Guelph weed scientist Dr. Peter Sikkema indicates pre-emergence herbicides will still deliver significant value for growers in dry spring conditions. He notes that… Read More

Plenty of things are showing signs of life right about now in Ontario, including the weeds. To determine how to control these yield-robbing plants in the weeks ahead, Bernard Tobin is joined by Rob Miller, agronomist at BASF, in this episode of the Corn School. Typically, a conversation on spring weed control is determined by what… Read More

With help from precision technology, corn growers are fully capable of conducting well-designed, logistically simple field trials that can help improve yield and profitability. When it comes to on-farm research, “that’s the beauty of today versus 30 or 40 years ago when I started in this business,” says Purdue University corn expert Bob Nielsen. On… Read More
