How does strip tillage impact a corn plant’s ability to access and take up nutrients? On this episode of RealAgriculture’s Corn School, Ben Rosser, corn lead at Ontario Ministry of Agriculture, Food and Rural Affairs, looks at fertility research plots that compare how corn performs in both conventional tillage and spring strip tillage systems. In… Read More
A lack of late-season nitrogen and denitrification has been a concern this year, which is causing less than optimal growth in corn crops in parts of Ontario. Matt Chapple, market agronomist at PRIDE Seeds, has been getting plenty of calls this growing season about the issue, and in this Corn School episode, Bernard Tobin joins… Read More
When it comes to strip tilling, is it better to plant corn into fall strips or spring strips? Ben Rosser, corn lead with the Ontario Ministry of Agriculture, Food and Rural Affairs, has been working on this question for a while now, and in this Corn School episode, Bernard Tobin catches up with him in… Read More
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
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
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
