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 crops have experienced widespread hail damage in recent weeks and many growers are asking how they can minimize the yield impact. In this episode of RealAgriculture Corn School, agronomist Peter Johnson takes us to a field of eight-leaf corn that has been shredded by a recent hailstorm. He says at this stage, yield loss… Read More
Have you ever spotted an area of vigourous plants in your cornfield and wondered why they’re a growth stage or two ahead of neighbouring plants? There are plenty of agronomic insights we can glean from our fields to improve farm management and yield, says AGRIS Co-operative agronomist Dale Cowan. Quite often the opportunity is right… Read More
Dan Foster has seen a lot of agronomic head scratchers in his career, but he witnessed a first in a cornfield near Sarnia, Ontario this spring. On this episode of Real Agriculture Corn School, Foster, Pride Seeds market development agronomist based at Chatham, takes you to a field with rootless corn syndrome. Foster describes how… 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
What a difference a year makes. In 2016, Ontario’s cold and dry spring conditions produced plenty of available nitrogen for the emerging corn crop. But when you fast-forward to 2017, those cold soils are now waterlogged and the wet conditions mean there’s very little nitrogen available to the crop. The wet soil conditions have a… Read More
Planting season can be a busy, chaotic time, but not paying attention to details, such as variation in seed size, can be costly and impact yield potential for the rest of the growing season. “There are no second chances as it relates to population. What you put in the ground now is what will make your… Read More
How much corn yield potential are you losing as the rain continues to fall across Ontario? As of May 5, you haven’t lost anything yet, but yield potential does start to diminish around May 10, says Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) corn specialist Ben Rosser. In this episode of RealAgriculture Corn… Read More
