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
Ever consider applying manure on corn in-crop using drag hose application? Many growers are scared off by the idea of dragging a hose over growing corn plants, but if your timing is right you can limit population loss, reduce compaction, and increase nutrient use efficiency, yield, and profitability. That’s the message Ontario Ministry of Agriculture,… Read More
The practice of split-applying nitrogen through the growing season has been increasing throughout U.S. midwest corn states and in Eastern Canada. In Western Canada, about 20 percent of corn growers in Manitoba have adopted the in-season practice, according to newly-released results of a survey conducted by the Manitoba Corn Growers. In this episode of RealAgriculture… Read More
When growing corn, many farmers utilize nitrogen stabilizers to protect their fertilizer investment. Agrotain has become a popular stabilizer choice for its ability to inhibit nitrification and protect nitrogen from ammonia volatilization. There are also products that protect against losses from denitrification and nitrate leaching. AGRIS Co-operative agronomist Dale Cowan says farmers can see a yield… Read More
Your farm has a nutrient management plan, but does it include your neighbours? A larger-scale plan is a great idea for intense livestock neighbourhoods that struggle to use manure efficiently. It also ensures nutrients stay in the field and out of tiles and waterways, says Ontario Ministry of Agriculture, Food and Rural Affairs field crop sustainability… Read More
How important is the number of rows on a corn cob? When row numbers shrink from 20 to 18 you could be looking at a 20-bushel per acre yield loss, says Illinois-based BASF agronomist Jeremy Hogan. On this edition of RealAgriculture’s Corn School, Hogan breaks down four components of yield – protecting row numbers, maximizing ear… Read More
If you’re targeting maximum corn yield, you need to fine-tune plant nutrition for a particular two-week period of the corn growing season, says Tony Vyn, professor of agronomy at Purdue University. That’s because while we’ve been focused on more rows and kernels per row per ear, modern hybrids can pack tonnes of yield in if… Read More
Do your corn fields yield less than 170 bu/ac? If so, you have to be careful when removing corn residue from those fields because you could be depleting the field’s soil organic matter. That was the message USDA research agronomist Shannon Osbourne shared with those attending the recent Southwest Agricultural Conference at the University of… Read More
In 1840, J. Von Liebig, a German chemist described as the father of the fertilizer industry, stated that “the rate of growth of a plant, the size to which it grows, and its overall health depend on the amount of the scarcest of the essential nutrients that are available to it.” Since its inception in… Read More
Ontario will set a new corn yield record in 2017 with the crop expected to hit an average of 180 bu/ac or better. Where is all that yield coming from? Corn physiologist Dr. Thijs Tollenaar has poured over the data and identified three key factors driving corn yield improvement. A long-time University of Guelph professor… Read More
