Where should growers place fertilizer in strip-till strips to best protect the seed from injury while optimizing nutrient uptake? Ontario Ministry of Agriculture, Food and Rural Affairs corn lead Ben Rosser says Ontario does have “safe rate” recommendations for in-furrow and 2″x 2″ planter banding but no guidelines are currently available for strip-till fertilizer placement….

The Christmas holidays are here! What better way to spend the time than catching some of the 30 Corn School episodes RealAgriculture published in 2022? We kicked off the season in January with Purdue University agronomy professor Dr. Tony Vyn who tackled the question: where does yield come from? Vyn notes that hybrid research over… 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

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 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

2021 was a big year for corn yield in Ontario. Although not official, the average yield is expected to check in at just over 200 bu/ac — a new record. On this episode of RealAgriculture’s Corn School, we take a closer look at where this yield is coming from with Purdue University agronomy professor Dr…. Read More

With high fertilizer prices heading into 2022, corn growers can’t afford to over-apply nutrients. But they also can’t risk losing money by shorting the crop of its fertility needs. On the season-ending episode of RealAgriculture’s Corn School for 2021, University of Guelph associate professor Dr. David Hooker returns to comment on this conundrum and share… Read More

A lack of late-season nitrogen and denitrification has been a concern this year, which is causing less than optimal growth in corn crops in parts of Ontario. Matt Chapple, market agronomist at PRIDE Seeds, has been getting plenty of calls this growing season about the issue, and in this Corn School episode, Bernard Tobin joins… Read More
