Soil acidity is an issue that’s gaining attention in the Northern Plains, especially in areas where no-till practices have been paired with high surface-applied nitrogen rates. “They’re seeing this advancing a lot faster in parts of North Dakota and Montana, under traditional zero till conditions where they broadcast urea fertilizer. They find they’re acidifying the… Read More

Tar spot has been spreading across North American corn growing regions ever since the leaf disease was first detected in 2015. Characterized by tar-like speckling on the upper surface of corn leaves, the fungal pathogen can deliver yield hits ranging from 20 to 60 bushels per acre (in highly infected fields). On this episode of… Read More

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

Fungicides are a key tool in the tar spot management toolbox. But what’s the best time for growers to apply a fungicide to get optimal control of the disease and the best return on their crop protection investment? On this episode of the RealAgriculture Corn School we catch up with Ontario Ministry of Agriculture, Food… 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

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

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
