It pays to manage corn stalks. That message was heard loud and clear when agronomists Pat Lynch and Jonathan Zettler asked farmers why they till soil following a corn crop. The pair publish The Cropwalker — a weekly agronomy newsletter, and heard from 372 respondents in a Twitter poll. The top reason for tillage, cited… Read More
Information, knowledge, and data can be paramount when maximizing yield potential, and when talking about utilizing fertilizer to its highest potential, accurately measuring nitrogen loss can translate to net dollars at the end of the year. On this Corn School episode, we talk about how measuring nitrogen volatilization is the first step in determining how… Read More
Why are corn hybrids that typically reach eight and nine feet tall coming up as much as two feet short? It’s a question many Ontario growers are asking this year as the crop pushes through grain fill. On this episode of the RealAgriculture Corn School, PRIDE Seeds agronomist Matt Chapple digs into the “short corn”… Read More
How much fertilizer do farmers lose when they apply nitrogen in season? Is volatilization a significant problem? Could 4R nutrient management and urease inhibitors help? On this episode of the RealAgriculture Corn School, University of Guelph researcher Josh Nasielski shares what he and his collaborators are learning about the best way to minimize in-season losses using… Read More
When it comes to planting and establishing corn in a cereal rye cover crop, the growing corn can be adversely impacted by rye’s allelopathic effects, the release of chemicals that inhibit the plant’s growth. But rye can also limit the amount of light, and quality of light, available to corn when it’s growing in the… Read More
Biostimulants designed to enhance performance and yield are nothing new in the corn management world. But growers can expect to see more and more of these products as manufacturers look to bring to market management solutions that alleviate the abiotic stresses plants experience when growing conditions are either too hot, cold, wet or dry. On… Read More
Protecting yield potential from northern corn leaf blight (NCLB) and a newer pest, tar spot, requires being well-armed and ready to apply the right fungicides at the right time. That’s because these diseases are not only big yield robbers, but the window to provide adequate control is quite narrow, and gets narrower with certain weather… Read More
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
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
Crop insurance deadlines may be looming, but the rush to get corn seed in the ground when it’s late in the planting window and soil conditions are wet can also cause problems, such as poor root development, later in the growing season. Sidewall compaction in the furrow is a common consequence of planting into wet… 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
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
