There are plenty of things farmers can add to soil other than a commercial fertilizer to add carbon and feed microbes. Increasingly, there are products that promise increased nutrient availability or even nitrogen-fixation for non-legumes. Whether or not the products work as they should and determining the best situation to use them is yet to… Read More

The right source, right rate, right time, right place for nutrients adds up to more efficient use of fertilizer dollars, and keeps nutrients in the fields and out of our water and air. On this episode of The Agronomists, host Lyndsey Smith is joined by Don Flaten, recently retired professor of soil fertility at University of Manitoba,… Read More
This Monday edition of RealAg Radio features a lot of agronomic info. We appreciate you tuning in! On the show you’ll hear: Don Flaten, professor emeritus of soil science at University of Manitoba, featured in an episode of Agronomy Geeks with Lyndsey Smith; Nate Ort of the Canola Council of Canada, on how to select… Read More
With 20 years of teaching and research achieved, Don Flaten says it’s time to retire. It’s a retirement well earned, as the soil scientist with the University of Manitoba has taught over a thousand students the ins and outs of soil, its importance, and revealed to many the complexity of nutrient interactions. Flaten has also… Read More
In today’s episode of RealAg Radio, host Shaun Haney challenges us to be curious during this conference season. Also in the show, you’ll hear: Top ag news with RealAgriculture’s Jessika Guse; An acreage forecast for 2020, and does tension in the Middle East create any challenges for Canadian ag exports? Chuck Penner, LeftField Commodity Research… Read More
Not only do dry soil conditions hamper seed germination, they also raise the risk of fertilizer toxicity for seedlings after they germinate, especially in a sensitive crop like canola. That means rates of fertilizer placed at seeding last year or the year before might not be safe this year, explains Don Flaten, soil scientist at… Read More
Phosphorus is a critical nutrient in farming, but it has also received a lot of negative attention for the impact it can have on water quality. If we consider the path of a single phosphorus molecule, it probably originates in a rock formation in the U.S. or North Africa. From there it becomes fertilizer and… Read More
Wet conditions prevented normal fall fertilizer application in parts of Western Canada last fall, leaving growers looking at options for delivering nitrogen to this year’s crop. As Don Flaten, soil scientist at the University of Manitoba, explains in this episode of Canola School, there’s no one-size-fits-all approach. Growers will have to consider their limiting factors… Read More
It’s been a long time since the last public research was conducted to support nitrogen fertilizer recommendations for wheat on the eastern side of the prairies. “The last time we did publicly-funded research on wheat yields and nitrogen fertilizer recommendations was actually about 45 years ago, so we were dealing with lower yielding wheat varieties… Read More
Growers topdressing melted urea to boost wheat protein should be asking their supplier whether it contains a contaminant that’s toxic to wheat, suggests a soil scientist at the University of Manitoba. With the introduction of higher yielding wheat varieties, there’s been new interest in applying post-anthesis nitrogen to wheat to boost protein content in Western… Read More
Granular phosphorus fertilizer recovered from liquid hog manure could be a viable alternative to traditional 11-52 monoammonium phosphate (MAP) fertilizer for growing wheat and canola, according to research done at the University of Manitoba. Struvite “looks like a fantastic fertilizer,” says Don Flaten, U of M soil scientist and one of the authors of a… Read More
The number of soil tests in Manitoba with phosphorus concentrations below the critical level for crop production grew by 7 percent between 2010 and 2015, according to the new North American Soil Test Summary published by the International Plant Nutrition Institute. Alberta, Saskatchewan, Manitoba and Quebec, as well as 13 U.S. states, all saw more… Read More
Farmers are dealt a hand of cards each year. There are cards of fortune and cards of misfortune. Maybe it’s a wet spring or corn prices below $4/bu or skyrocketing fertilizer costs. Maybe you get all three in the same hand. A farmer can’t always choose what they’re dealt, but they can choose how to respond…. Read More
Knowing full-well that the crop can experience seed burn if placed too close to phosphorous (P), many soybean farmers will apply no or very low rates of phosphate with their soybeans. And, as we learned in the last Soybean School, that choice may not be hampering short term yields. But, agricultural soils are seeing losses in available P, suggesting room for… Read More
Soybeans are serious consumers of phosphorus, so it seems logical that supplying P fertilizer would be important for maximizing soybean yields, right? That’s wrong, at least in the short-term, according to research results in southern Manitoba. Researchers from the University of Manitoba and Manitoba Agriculture are comparing how soybeans respond to three rates of P2O5 fertilizer (20,… Read More
