Corn rootworm, manure, and soybeans — farmers don’t often hear those three words in the same sentence but we’ve come to expect the unexpected in 2020. With growing resistance to corn rootworm traits in Ontario, many farmers who typically plant continuous corn will look to control the pest by expanding rotations to include soybeans. But… Read More

Corn fields across Ontario are full of variable plant development and that should be a concern for growers, says University of Guelph crop researcher Dr. David Hooker. Fields are littered with areas of yield-compromising backward and slow-to-develop plants. Hooker believes corn variability is even more apparent this year due to significant weather challenges; with cold… Read More
With June arriving this week, corn is rushing ahead and growing rapidly. Now’s the time for growers to get out and scout fields to identify planting issues, determine yield potential and start fine-tuning your management plan, says Kinburn, Ont., agronomist Paul Sullivan. On this episode of RealAgriculture’s Corn School, Sullivan notes that stand assessment and… Read More
Does timing matter in strip till? Will corn planted into fall-made strips out-yield spring strips? That’s just one of many questions corn growers are asking as strip tillage gains popularity as a reduced tillage option that delivers the benefits of conventional tillage, says Ben Rosser, corn lead for the Ontario Ministry of Agriculture, Food and… Read More
When it comes to corn fertility and higher yield, nitrogen is the star of the corn production show. But Carleton Place, Ont., farmer Mark Foster and agronomist Paul Sullivan feel it’s time potash received its share of the spotlight. At the SouthWest Agricultural Conference earlier this month, the pair shared how they have unleashed the… Read More
One of the big benefits of strip tilling corn is the ability to place fertilizer directly into the berm or strip for greater nutrient efficiency. But as growers rotate out of strip-tilled corn, how can they assess the overall fertility of a field where nutrient placement was concentrated in specific areas? On this edition of… Read More
Part of the attraction of strip till corn is the ability to cultivate strips in the fall and place fertilizer. It makes for less work in the spring when the field work window is compressed. Those fall strips in heavier soil also help warm the planting zone. But what about fertility — how does corn… Read More
Starter fertilizer can give a corn crop some early-season punch, but if you’re not careful with application rates those new plants could get knocked out by fertilizer burn. Banding fertilizer in a 2-by-2 band beside the seed promotes early growth and vigour but too much nutrient too close to the seed can injure roots and… Read More
Strip till corn is helping Mark Brock build a winning management system for his Staffa, Ont., farm. Brock started strip tilling back in 2015 with the objective of integrating manure from the farm’s chicken operation into a system that would help manage compaction, and further improve soil organic matter with the addition of cover crops….

Ontario’s cool spring is having a huge impact on the soil release of nitrogen. RealAgriculture agronomist Peter Johnson says he’s seen the impact on the wheat crop already, and growers will have to keep a sharp eye on nitrogen soil tests to ensure they’re meeting the needs of the growing corn crop. In this Corn… Read More
Ontario’s corn crop — such that it is — is pretty much planted, as most growers are now turning their focus to soybeans. Across the province during the past month, corn was planted into a range of wet, miserable conditions. The question now is how will the seedlings handle the tough going and what can… Read More
Breaking yield records has become routine for modern corn hybrids. Much of the credit goes to new and improved genetics, but those bin-busting yields also require more nutrients, and that demand extends well beyond N, P, and K. “As we continue to raise the yield bar we need to start looking at micronutrients with a… Read More
Imagine planting corn hybrids that could produce 40 to 80 percent of their nitrogen requirements. It’s only 10 years away, says University of Wisconsin–Madison researcher Dr. Vania Pankievicz. The breakthrough comes from a Mexican corn variety called Sierra Mixe. At the recent Innovative Farmers Association of Ontario conference in London, Ontario, Pankievicz explained that the 15-foot tall variety,… Read More
Have you ever discovered small, misshapen, poorly pollinated corn ears mixed in with a field of impressive, high-yielding cobs? PRIDE Seeds agronomist Drew Thompson received a call in August from a grower telling just this story. When Thompson visited the field he noted that no nutrient deficiencies were apparent (no firing or discolouration) so out came… Read More
Mike Dolinski has seen a lot of things over the years as an entomologist and senior Agri-Trend coach. Opinions that come and go, scientific consensus that changes, and sometimes catchphrases that catch on, even if they are misleading. At the recent Sure Growth Technologies field day near Marchwell, Sask., Dolinski drew a bead on the… Read More
