  • Starting Clean More Critical Than Ever

    Fifteen years ago, University of Guelph’s Dr. Clarence Swanton helped revolutionize weed control with his pioneering research on the critical weed-free period for soybeans and corn. Essentially, Swanton helped usher in the thinking that weeds that emerge with or shortly … Continue reading →

  • Soybean School West: Adding Moisture

    Researchers say “reconditioning” is one way to increase the value of your soybeans in storage if they were too dry at harvest. Continue reading →

  • Soybean School West: The Rotational Approach to P Needs in Soybeans

    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 West, that choice may … Continue reading →

  • Soybean’s Relationship Status with Phosphorus: It’s Complicated

    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 … Continue reading →

  • Soybean School West: Testing the Belief that Black Soil is Best for Planting Soybeans

    Preliminary research conducted in southern Manitoba is casting some doubt on the common belief that dark, tilled soil is best for planting soybeans in northern growing regions. Greg Bartley, a graduate student working together with Dr. Yvonne Lawley at the … Continue reading →

  • Checking for Root Rots and Seedling Diseases

    Poor emergence or damping off of young soybean plants can be a sign of a seedling disease or root rot problem, especially following cool, wet weather as experienced in much of the soybean growing part of Western Canada this spring. … Continue reading →

  • Making the After-Frost Replant Call

    Soybeans can handle slightly colder temps than corn, but their exposed growing point means that frost damage can be far deadlier and permanent. That seems to be the case across much of Ontario, as farmers head to the fields to … Continue reading →

  • Seeding rates, inoculants and seed treatments

    Soybean planting time brings with it a number of decisions — what’s the optimal seeding rate? Which inoculants should be used, and should they be doubled up? What about seed treatment? Is a seed treatment with insecticide needed? As part … Continue reading →

  • How to Pick the Best Varieties Based on Yield Potential

    You’re looking at yield data from last year trying to figure out which soybean varieties to grow in 2015 — how do you know when the yield difference between two varieties is meaningful? “That’s a question we get all the … Continue reading →

  • Is Manitoba Still Free of Soybean Cyst Nematode?

    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 … Continue reading →

  • An Inside Look at Grading Soybeans

    Want to know what buyers look for in a soybean sample? Or what you don’t want to see in your soybeans? This episode of the Soybean School West takes us to the Canadian Grain Commission grading lab in Winnipeg. Thanks … Continue reading →

  • What’s the Right Amount of Tillage for Soybean Residue?

    Can deep-tilling soybean residue be justified? A researcher from the University of Manitoba is looking at whether tillage practices need to change as farmers in Western Canada grow more soybeans. Despite leaving less plant matter behind than most crops, it’s not uncommon to … Continue reading →

  • Assessing Impact of Frost on Soybeans

    Soybean growers in Western Canada and the Northern U.S. have been up early over the last few mornings checking how low temperatures dropped overnight. The thermometer has dipped below the freezing mark in some areas, with damage to soybeans depending … Continue reading →

  • What Fall Scouting Can Teach You, Plus Row Width vs. Solid Seeding Decisions

    So you’re thinking of switching to a wider row spacing for next year’s soybeans. Have you taken your hula hoop around this year’s crop first? Though there isn’t necessarily an “ideal” row spacing suggested for western Canadian soybean growers, the … Continue reading →

  • Brown Spot, Downy Mildew & Herbicide Injury – Which is it?

    July 15th, 2014-     Soybean growers in Manitoba are — so far — rather lucky. While there are diseases in the province that infect soybeans, like downy mildew, white mold (sclerotinia) and brown spot, overall pressure is relatively low. That … Continue reading →

  • Identification and Management of Chlorosis

    Chlorosis, or yellowing of leaf tissue in plants, can be an indicator of a great number of issues from nutrient deficient soils to poor root systems or saturated soils. Manitoba farmers especially are dealing with excess moisture this year, even … Continue reading →

  • The Insect and Disease Scouting Calendar

    What’s the toughest part of trying out a new crop? Once you get the equipment set up sorted out at seeding and harvest, it’s on to crop diagnostics. Mother Nature tends to give farmers a bit of a break when … Continue reading →

  • Must Have Tools for Evaluating Stand Establishment

    How close did you get to achieving the soybean plant density you were aiming for? What’s the yield potential of the stand you have? The only way to get a bead on those answers is to get out and scout … Continue reading →
