Corn growers often turn to tissue testing to diagnose a problem. When plants in a field are yellowing or pale, grabbing a sample and sending it to the lab can seem an obvious way to confirm a nutrient deficiency. But there’s more to the tissue testing story than simply identifying a problem and finding a… Read More
In Ontario, corn growers are approximately six weeks into the growing season and now is a great time to do a couple tests to reassess the nitrate levels and decide on what the best plan is to sidedress nitrogen, on a field by field basis. Deb Campbell, agronomist with Agronomy Advantage, joins us for this… Read More
We’re back with another episode of The Agronomists, and as always, we’re excited to be here. Today’s show — hosted by Lyndsey Smith — features Greg Stewart of Maizex Seeds and Elizabeth Karpinchick of Tone Ag. The trio discusses in-crop N applications in the corn crop (and more). The Agronomists is brought to you by… Read More
The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) will not be performing soil nitrate tests for public extension this growing season. Which begs the question: will it pay for farmers and agronomists to draw tests in corn fields anyway? The answer — if the field saw any manure or red clover the in… Read More
The race is on for many corn growers as they hustle to apply post-emergent herbicides to control yield-robbing weeds. The duration of the post-emergence application window depends on the herbicide. A product like glyphosate can be applied all the way up to the 8-leaf stage. But other herbicides have tighter timing and need to be… Read More
When it comes to corn, even emergence and uniform plant growth is a well-known recipe for a high-yielding crop. New research also shows that even emergence is a significant contributor in the fight against gibberella ear rot and deoxynivalenol (DON) accumulation and other mycotoxins associated with the disease. On this episode of RealAgriculture’s Corn School, University… Read More
Whether the corn crop is just being planted or is emerging in the field, it’s time to do some digging around. If the crop hasn’t emerged yet, you can still do some diagnostics to evaluate how everything is going and get a better understanding of the corn root, and how the corn plant is growing…. Read More
It’s the last Wheat Pete’s Word of May! Very quickly are the growing months going to fly by… On this episode of Wheat Pete’s Word, host Peter Johnson discusses wild weather, why talking to the public matters, the importance of not beating yourself up, and so much more. Have a question you’d like Johnson to… Read More
Much of Ontario’s corn crop has shot out of the ground and is carrying tremendous yield potenial as June draws near. But while many growers are reporting corn emerging as quickly as five days after planting, RealAgriculture agronomist Peter Johnson has noticed a significant number of corn kernels that are corkscrewing underground, with plants struggling… Read More
The Ontario Ministry of Agriculture, Food and Rural affairs has tapped Colin Elgie as the province’s new soil fertility specialist. Elgie fills a gap created in the OMAFRA soil management team in 2019 with the retirement of long-time OMAFRA soil management specialist Adam Hayes. Jake Munroe, who formerly handled the soil fertility duties, moved into… Read More
Not all glufosinate ammonium herbicide formulations are the same. This is especially important to note in areas that grow both glufosinate-tolerant (aka LibertyLink) corn and canola. A corn grower in Ontario, or in the Midwest U.S., who orders Liberty or glufosinate from a retailer would likely receive a formulation containing 200g of active ingredient per… Read More
Waterhemp, the invading resistant weed, often misidentified as redroot, green, or smooth pigweed, continues to build resistance against herbicide control in Ontario. University of Guelph weed scientist Dr. Peter Sikkema and his research team have now confirmed waterhemp resistance to Group 27 herbicides in the province. He shared the news earlier this week during a Ridgetown/Simcoe… Read More
When it comes to determining the right rate of nitrogen for your farm there’s nothing better than on-farm data. After a winter of talking with growers about escalating nutrient prices and the most economic rate of nitrogen (MERN), Ben Rosser, corn lead with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) is encouraging… Read More
A cool, wet spring has slowed fieldwork and dreams of early planting appear to be disappearing as the calendar turns to May. But the backward conditions have not stalled weed growth in fields across Ontario. That means growers will need to keep a close eye on winter annuals and mounting weed pressure in soybean and corn… Read More
As warmer weather arrives and fields start to dry up, many growers are tempted to begin field work in preparation for planting. Working soil that’s not fit, however, can prove problematic later in the spring and throughout the growing season. On this episode of RealAgriculture’s Corn School, we catch up with PRIDE Seeds agronomist Matt… Read More
