Corn School: How much corn residue should you remove?

Do your corn fields yield less than 170 bu/ac? If so, you have to be careful when removing corn residue from those fields because you could be depleting the field’s soil organic matter. That was the message USDA research agronomist Shannon Osbourne shared with those attending the recent Southwest Agricultural Conference at the University of… Read more »

PowerRich: Micros key to yield and profit

In 1840, J. Von Liebig, a German chemist described as the father of the fertilizer industry, stated that “the rate of growth of a plant, the size to which it grows, and its overall health depend on the amount of the scarcest of the essential nutrients that are available to it.” Since its inception in… Read more »

Corn School: Understanding 30 years of rising yields

Ontario will set a new corn yield record in 2017 with the crop expected to hit an average of 180 bu/ac or better. Where is all that yield coming from? Corn physiologist Dr. Thijs Tollenaar has poured over the data and identified three key factors driving corn yield improvement. A long-time University of Guelph professor… Read more »

Corn School: How long does it take to add 1 percent soil organic matter?

You’ve just finished combining a corn field and you want to know how much organic matter all that corn residue will contribute to your soil. RealAgriculture’s agronomist Peter Johnson tackles that question on our latest Corn School episode. Unfortunately, as Johnson explains, all those stalks and cobs won’t have much of an impact. When it… Read more »

Corn School: ‘Wins’ of spring 2017

2017 may well be remembered for the spring that just kept on giving. From flooding to hail, Mother Nature threw just about every challenge imaginable at Ontario farmers during the early portion of the growing season. But despite difficult conditions that wreaked havoc on spring tillage, planting, weed control and nutrient application, farmers have persevered…. Read more »

Corn School: Does wet soil need more nitrogen?

The rain keeps falling in Ontario and all the water-logged soils make it tough to get a good read on how much nitrogen is available to the province’s corn crop. In this edition of RealAgriculture Corn School, agronomist Peter Johnson discusses whether corn acres need supplemental nitrogen and how much they might need. It depends on… Read more »

Corn School: Cool weather calls for more sidedress nitrogen

Ontario’s cool, wet spring not only delayed planting, but also put the brakes on nitrogen mineralization, limiting the nutrient’s availability to the growing corn crop. According to OMAFRA pre-sidedress nitrate testing (PSNT) survey results released this week, corn growers are looking at the lowest rates of available nitrogen since the survey began in 2013. In… Read more »

Corn School: Time to start talking NPK and S

The N-P-K conversation – nitrogen, phosphorous, potassium – is the focus of most corn nutrient management discussions. But is it time for the letter S (sulphur) to be a routine part of that conversation? In this edition of RealAgriculture Corn School, AGRIS Co-operative agronomist Dale Cowan is joined by crop sales specialist Mike Veenema to… Read more »

Corn School: Cold and wet means less available nitrogen

What a difference a year makes. In 2016, Ontario’s cold and dry spring conditions produced plenty of available nitrogen for the emerging corn crop. But when you fast-forward to 2017, those cold soils are now waterlogged and the wet conditions mean there’s very little nitrogen available to the crop. The wet soil conditions have a… Read more »

Corn School: Knowing vs Hoping — Randy Dowdy’s Principles for Growing Record Yields

There are many aspects of farming that are beyond a farmer’s control (weather, markets…), but there are also variables that can be managed better than they have been in the past, according to the Georgia farmer who has set world corn and soybean yield records. “We make big yields and we blame the weather. We make… Read more »

Ontario CCAs Taking Lead on 4R Nutrient Management

Almost half of North American Certified Crop Advisors (CCAs) holding a new 4R Nutrient Management designation reside in Ontario. That puts Ontario’s crop advisors at the forefront of efforts to help farmers and agriculture improve water quality, environmental stewardship and sustainability, says Ontario Certified Crop Advisor Association executive director Susan Fitzgerald. Earlier this week, the… Read more »

Corn School: Turning Agronomic Insight Into Yield Results

With corn planting just around the corner, it’s time to take stock of agronomic advice we learned this winter and take it to the field. In this episode of Real Agriculture Corn School, Bernard Tobin and Pride Seeds market agronomist Aaron Stevanus review research findings and agronomic management insights that emerged during the winter meeting… Read more »

Seven Corn Management Ideas for 2017

Put two great corn minds together and you come up with seven corn management concepts to help you boost yields in 2017. University of Guelph professor Dr. David Hooker and Maizex agronomist Greg Stewart shared the results of their brainstorm with growers attending the recent Southwest Agricultural Conference, held at the University of Guelph’s Ridgetown… Read more »

A Smooth Ride For Fertilizer Spreaders

It all comes down to more acres per day for John Deere’s new F4365 high capacity nutrient applicator. At the recent Farm Progress Show in Boone, Iowa, John Deere product manager Jason Beuligmann showcased the new, 330-cubic-feet dry spinner spreader. He explained that the company’s engineers had two goals in mind for the design – operator comfort,… Read more »

Corn School: Testing Nitrogen With ‘Tailgate Technology’

Fine-tuning nitrogen rates promises to get easier with the arrival of ‘tailgate technology’ that allows growers to test for nitrates on the tailgate of their truck. That means no more couriering soil samples to the lab, or waiting for up to three days for results in the busy season. In this episode of the Corn School,… Read more »
