Soybeans are most often grown places that get abundant rain, particularly in August. This usually happens in southern Manitoba, so an unusual problem is emerging there: soybeans are drying down, but staying green. In this episode of the Soybean School, RealAgriculture’s Dale Leftwich talks to Glenda Clezy, regional grow team advisor with Federated Co-op, about soybeans… Read more »

Soybean School: No quick fix for managing protein
The introduction of protein price discounts by at least one soybean buyer in Western Canada this past winter has left soybean growers wondering what can be done to ensure Prairie soybeans are high enough in protein content. Unfortunately, there’s no quick or easy management fix, says Dennis Lange, pulse and soybean production specialist with Manitoba… Read more »
Soybean School: Understanding the total yield cost of bin-run seed
There are certainly unknowns and risks that come with planting bin-run soybean seed versus certified seed, but one significant piece of information has been confirmed by crop insurance data in Manitoba: older, off-patent varieties don’t have the same yield potential as newer varieties. As Dennis Lange, pulse specialist with Manitoba Agriculture, points out in this… Read more »
Soybean School: Understanding iron deficiency chlorosis risk heading into planting
As planting decisions are finalized, the risk of iron deficiency chlorosis (IDC) is one of the factors soybean growers in Western Canada and the Northern Plains are keeping in mind after unprecedented yellowing due to IDC in many areas last year. A wet 2016 growing season followed by a dry start to 2017, left elevated… Read more »
Soybean School: Preparing to battle SCN when (not if) it is found in Western Canada
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 »
Soybean School: How do researchers unlock higher yields?
Does throwing the kitchen sink at your soybean crop provide an economic yield response? The answer is a definitive “No” says University of Minnesota associate professor Seth Naeve. His conclusion is based on the the results of a huge three-year U.S. study that he shared with growers attending the Southwest Agricultural Conference in Ridgetown, Ont.,… Read more »
Soybean School: Preventing those yellow patches next year
Most of the yellow patches in soybean fields in Western Canada and the northern U.S. have disappeared as the plants have recovered, or turned necrotic and died, but one of the big questions heading into harvest is: what toll did widespread issues with iron deficiency chlorosis (IDC) earlier in the season take on yields? The… Read more »
Soybean School: Planting on corn rows costs money
It pays to steer clear of those corn rows when planting soybeans. In this episode of RealAgriculture Soybean School, Syngenta agronomist Eric Richter explains that planting directly on, or too close to, last year’s corn row produces seed mortality rates between 50% to 80%. He notes that it really doesn’t matter whether growers are pulling… Read more »
Soybean School: Monitor seed size variation between varieties and seed lots
The race is on in many areas — and hopefully soon will be in others — to get this year’s soybean crop in the ground. It’s critical to make some pit-stops along the way to adjust the planter or drill for optimum performance, as covered in this Soybean School episode. Seed size can vary widely,… Read more »
Soybean School: Know Your Agronomic Risk When Planting Off-Patent Soybean Seed
Not only are there legalities that need to be considered when purchasing and planting off-patent soybean seed, as we discussed in an earlier Soybean School feature, but there are also agronomic considerations. Due to the nature of the off-patent soybean seed market, assurances for the grower on maturity, germination, quality, and purity are often lacking… Read more »
Soybean School: These Aren’t Your Grandpa’s Varieties
How have soybeans changed over the past century, and what can growers learn from this evolution? Purdue University agronomy professor Shaun Casteel has some answers. Speaking at the recent Ontario Certified Crop Advisor annual conference, Casteel shared insights from his research comparing varieties from 1923 to those available in 2011. In this episode of Real… Read more »
Soybean School: Are Your Rows Too Wide?
Preliminary results from a three-year research project in North Dakota show row spacings in many soybean fields are too wide to reach their maximum yield potential. A team of agronomists and extension agents at North Dakota State University are surveying growers to generate baseline data on soybean management practices in the state. Their goal is to… Read more »
Soybean School: Breeding for 000 Maturity Ratings
The amazing rise of soybean acres across Manitoba and into Saskatchewan is possible only because of the development of early, early soybean lines. Just how early? While zeros and double zero maturity ratings are great for “short” season areas in Ontario and Quebec, it’s the triple zero lines that shine in places like Arborg, Manitoba,… Read more »
Soybean School: Counting Pods and Plants to Make a Yield Estimate
It’ll be a few weeks before we actually know how this year’s soybeans are going to yield, but we can get a pretty good idea now, especially if we’re willing to put some time into building a good sample size for making an estimate. Dieter Schwarz, the new market development manager for corn and soybeans… Read more »
Soybean School: Refining the Soybean Aphid Threshold to Factor in Friendly Bugs
When soybean aphids start multiplying in soybean fields, the decision to spray is typically triggered by the number of aphids found on each plant. The threshold for growers in Western Canada is usually reached when there are an average of 250 aphids per plant on 80 percent of the plants. The population should still be… Read more »
