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

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

2017 may well be remembered for the spring that just kept on giving. From flooding to hail, Mother Nature threw just about every challenge imaginable at Ontario farmers during the early portion of the growing season. But despite difficult conditions that wreaked havoc on spring tillage, planting, weed control and nutrient application, farmers have persevered…. Read More

The rain keeps falling in Ontario and all the water-logged soils make it tough to get a good read on how much nitrogen is available to the province’s corn crop. In this edition of RealAgriculture Corn School, agronomist Peter Johnson discusses whether corn acres need supplemental nitrogen and how much they might need. It depends on… Read More

Ontario’s cool, wet spring not only delayed planting, but also put the brakes on nitrogen mineralization, limiting the nutrient’s availability to the growing corn crop. According to OMAFRA pre-sidedress nitrate testing (PSNT) survey results released this week, corn growers are looking at the lowest rates of available nitrogen since the survey began in 2013. In… Read More

The N-P-K conversation – nitrogen, phosphorous, potassium – is the focus of most corn nutrient management discussions. But is it time for the letter S (sulphur) to be a routine part of that conversation? In this edition of RealAgriculture Corn School, AGRIS Co-operative agronomist Dale Cowan is joined by crop sales specialist Mike Veenema to… Read More
