Excessive water on crops can happen several different times in the year. Mother Nature has the final say on when too-wet soil conditions occur, but good soil structure and avoiding compaction can minimize the length of time roots stay submerged. When looking at the concept of water-logging — when your plants have too much water… Read More

It’s time for Day 3 of Ontario Diagnostic Days! The annual Ontario crop diagnostic days were back in the field on July 20 and 21, 2022, but only at Ridgetown campus University of Guelph. Not everyone could attend these two field days, so the organizing committees of these highly successful in-field education and learning events are… Read More
A word that continues to surface when carbon offsets come up is permanence. The idea that longevity in the practices implemented in order to generate or claim carbon offsets needs to be defined. Dr. Mario Tenuta, professor of applied soil ecology in the department of soil science at University of Manitoba, says that it’s a… Read More
Thanks for tuning into this Tuesday edition of RealAg Radio. Today’s show is a virtual on-location brought to you by Syngenta Canada and Saltro! On today’s show you’ll hear: Dr. Mario Tenuta of the University of Manitoba, who’ll talk about how permanence will apply to carbon sequestration; Abhi Deora of Syngenta joins us for a… Read More
It’s an Agronomic Monday edition of RealAg Radio. On today’s show you’ll hear from: Tom Wolf of Sprayers 101, with key tips for winterizing the sprayer; Ken Schaus of Ont., on some interesting soil-related practices happening on his farm; Dr. Mario Tenuta, University of Manitoba professor, on soil carbon and carbon sequestration; and Steve Denys… Read More
Soil management, soil structure, and soil health have all become incredibly important topics in all crop and pasture planning conversations. Many of those conversations centre on one particularly complicated topic: carbon. What is it? How do we add it to soil? How do we keep it there? If there’s one person who can at least… Read More
There’s a new research project underway and a soil scientist from the University of Manitoba is taking the lead on the team. Dr. Mario Tenuta will be guiding a team of Canadian researchers to determine best practises on how to apply nitrogen fertilizer in corn crops in ways that not only increase yields and economic benefit… Read More
Soybean growers in Western Canada have not yet had to face a soil-borne pest that has hurt yields in other soybean growing regions, but it’s only a matter of time. Soybean cyst nematode (SCN) has steadily spread north along the Red River and has been found in soils on at least two farms near the… Read More
If farmers are going to pay a tax on carbon emissions, they should also receive credit for the carbon their farms remove from the atmosphere. Many in the farm community are trying to make that case, as the federal and provincial governments roll out pricing systems that appear to lean on the cost side of the… Read More
Mario Tenuta has been studying greenhouse gas emissions in agriculture for longer than he’s willing to admit. Never before has he seen this much interest in the topic. “We’ve always had interest in carbon sequestration and the use of nitrogen fertilizers and manures, but now where we are called to some form of action and reductions, now… Read More
If the world of soil biology had its own version of Facebook, crops like peas, lentils, corn and flax would be listed as “in a symbiotic relationship” with mycorrhizal fungi. The microscopic organisms help these crops access phosphorus in the soil. Wheat would probably be friends with mycorrhiza, as cereals see some benefit from having… Read More
There’s potential for much more composting in North American farming, say researchers at the University of Manitoba. “Turning waste into gold” was the theme for the annual field day at the U of M’s Glenlea Research Farm last week. Mario Tenuta, soil ecologist at the University of Manitoba, describes the value of farm-scale composting of manure,… Read More
Manitoba farmers whose soil test results say they have soybean cyst nematode in their soil may want to get a second opinion, says a soil ecologist from the University of Manitoba. While the number of soybean acres has exploded on the eastern side of the Prairies over the last few years, Western Canadian growers have… Read More
