Late Application of Nitrogen

Late season nitrogen application

Corn N ChartLate season nitrogen application has been a hot topic amongst farmers and uptake in this practice has increased in recent years. The expense and environmental impact has made growers think differently about nitrogen application.

Weather extremes has also caused growers to change the way they apply nitrogen to mitigate loses from excessive rainfall when applying all their nitrogen ahead of planting. Read more

Is it your intention to apply nitrogen in-crop to your corn?

Your farm has several options to consider utilizing this year:

  • Traditional sidedress 28%, perhaps at knee high corn
  • High clearance 28% application at V6 to V8 leaf stage with your own self-propelled applicator using drag hoses, Y-drops or streamer nozzles, or…

Introducing Thompsons NEW high-clearance RoGator for urea application!

Apply in-crop urea at V6 to V8 leaf stage with a self-propelled custom applicator airflow RoGator, owned and operated by Thompsons Limited.

If you consider the following chart, showing the uptake of nitrogen throughout the corn growing season, a significant portion of the nitrogen requirement occurs from tasseling to physiological maturity (black layer).

An in-season, planned, application of nitrogen allows you to more precisely meet the nitrogen requirements of your corn crop. In addition, we now have the ability to test for soil nitrogen, in field!

New for 2016

We now have the ability to test for soil nitrogen, right in the field!

Using Thompsons N-Gauge, our 360 SoilScan unit, we will have nitrate results in minutes.

To make the most out of an in-crop application of 28% or urea, it is strongly recommended that the nitrogen be treated with an inhibitor (Agrotain) that protects the nitrogen from ammonia volatilization, denitrification and nitrate leaching.

Automatic Soil Sampling

To sample, or not to sample (soil). Who’s right?

Some of your neighbours have stopped soil sampling. Others are sampling more than ever.


In any year, at most 10 per cent of the fields are soil sampled,” says Tom Jensen, a director in the North American program of the International Plant Nutrition Institute. “Some people say 20 per cent of farmers do some soil testing, but they may only do it every couple to three years.”

Farm consolidation is one factor that’s leading to the decline. Soil sampling can be a prohibitively time-consuming procedure for 10,000-acre farms, and these operators may opt instead for a standard fertilizer recommendation for each crop type, rather than each field. Nutrient rates are also adjusted based on target yields and what each crop is expected to remove. Read more

Course to certify Ontario producers for class 12 pesticides

By Owen Roberts, 

A free half-day course is being offered to help Ontario farmers become certified for buying and using grain corn and soybean seed treated with Class 12 pesticides (imidacloprid, clothianidin or thiamethoxam), popularly called neonicotinoids.

The course, called the Integrated Pest Management (IPM) Course for Corn and Soybeans, is being made available through the University of Guelph’s Ridgetown campus and sponsored by the province.

As of next Aug. 31, buying and using neonicotinoid-treated corn or soybean seed will only be possible with training and certification. Certification is valid for five years. Up to seven people can be supervised to plant under this certification.

Participants will learn IPM principles (including corn and soybean pest identification), planting best management practices, the new regulatory requirements regarding Class 12 pesticides and pollinator protection from neonicotinoid exposure.

“The aim of this course is for farmers to further understand how to apply [integrated pest management] concepts to their own corn and soybean fields, specifically for the early season pests,” says Wentworth County farmer and Ontario Federation of Agriculture director Drew Spoelstra. “They’ll learn how to look for these pests on their farms and consider all the options for managing them.”

The in-class course starts Nov. 3 in Ridgetown. It will be followed by sessions in Woodstock, Verner, Simcoe, Elora, Wyoming, Winchester, Harrow, Clinton, Lindsay and Vineland Station. Participants can sign up for these and other courses at or by calling 1-866-225-9020.

The online course also starts Nov. 3. It requires four hours of commitment over two days. High-speed internet and computer competency are required.

There are no requirements for using non-treated seed or fungicide-only treated seed. Class 12 pesticides do not include seed for popping corn, sweet corn, or corn used for the production for seed (seed corn) or soybean seed grown for certified status in accordance with a seed production contract (seed soybeans).

Farming for profitability

Precision ag systems can take your ability to analyze profits way past yesterday’s cost-revenue calculations

By Ralph Pearce, Country Guide Production Editor

It’s been the mantra of agricultural economists, bankers and even agronomists for the past 20 years. “Know your cost of production.” At every podium at every conference, you can almost guarantee the question is going to get asked. How can a farmer farm successfully without knowing their cost of production?

We’re always told every successful corporate executive outside of agriculture knows the cost of their widgets or grommets, usually down to the last fraction of a penny.

Then the question comes again: Can agriculture afford to be different?

But agriculture HAS changed, especially in the past 10 to 15 years, maybe not because the idea of farming for profitability is so new (it isn’t) but because farmers now have the ability to measure specific properties on the farm, from fertility levels to soil organic matter percentages to cation exchange capacity.

Of course, farming has also changed because the numbers are getting so much more volatile, which puts additional pressure on farm decision-making, not just from year to year but sometimes from one week to the next.

“It’s not precision ag anymore, it’s agronomy.” — Mike Wilson, Advanced Agronomy Solutions Manager, Thompsons Limited

The equipment and systems used to support these decisions are far more complex than they were even five years ago, just as the complexity of our seed technologies has leapt ahead, with double- and triple-stacked traits as well as drought tolerance and above- and below-ground pest protection. It’s a new universe compared to when Bt genetics first hit the market in the early 1990s. Read more

Reduce production costs without sacrificing yield

Falling commodity prices mean growers are concerned with their profit per acre. Input costs have remained high and have not adjusted to where farmers believe they should be. Until prices change, strategic adjustments will have to be made to stay profitable during lower commodity pricing years. Thompsons has identified 5 ways to help you reduce production costs without sacrificing yield.
