From moisture to nutrients, plant roots play a critical role in feeding corn throughout the growing season. On this episode of the RealAgriculture Corn School, Sullivan Agro agronomist Paul Sullivan looks at some of the problems growing plants can run into as they push down into the soil looking to feed the plant, fuel cob… Read More

Soil, water and topography maps — more commonly know as SWAT Maps — are becoming a familiar management tool for corn producers. These high-resolution soil foundation maps are used to execute variable rate fertilizer, seed, soil amendment and pesticide applications. On this episode of the RealAgriculture Corn School, host Bernard Tobin catches up with Sullivan… Read More

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

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
