Too wet isn’t good, but neither is too dry for growers looking to get the most value for soybeans. According to researchers at North Dakota State University, on a 40 bushel-per-acre crop, harvesting soybeans at 9 percent moisture rather than 13 percent will cost the farmer around 1.8 bushels per acre. At $10 per bushel, that’s… Read More
John Deere’s new ExactEmerge retrofit kit will allow farmers who own the company’s late-model planters to step up their speed and accuracy. John Deere launched its ExactEmerge seed delivery system in 2014, promising farmers precise seed placement and spacing while boasting the ability to travel at much faster planting speeds, up to 10 mph. The… Read More
Pride Seeds’ Dan Foster explains how to estimate soybean yield in this video, shot at Canada’s Outdoor Farm Show. Estimating yields may be more challenging than some of our other annual crops, but it all boils down to a total number of (viable) seeds in a given area. For soybeans, estimating yield without counting every seed over an… 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
The 2015 soybean crop has had its share of issues. From a late May frost that had many farmers replanting, to wet conditions that prevented replanting or late planting, and some zero-till beans that really struggled to get through heavy residue, it’s no wonder this crop is variable at best. While the window for most… Read More
Heterodera glycines or soybean cyst nematode (SCN) was first identified in Ontario in 1987, after over 30 years in North America. It’s original introduction is believed to have occured in the late 1800s, when settlers brought soil from Asia to supply the proper bacteria for soybean root nodulation. “Of the ten major diseases of soybeans… 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
Ask three farmers what the best row spacing is for soybeans and you might get three different answers, but in most soybean growing areas there’s been a trend back toward wider rows. As part of this Soybean School episode, Horst Bohner, soybean specialist with Ontario’s Ministry of Agriculture and RealAg’s Bernard Tobin discuss the driving factors in why… Read More
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 University of Manitoba, is in his second year of comparing how soybeans respond when planted into different… Read More
If you’ve noticed more than a few fleabane “escapes” in recent years, you’re not alone. Glyphosate resistant Canada fleabane has spread across more than 700 kilometers of Ontario crop land in just five years. Despite its incredible distribution, Canada fleabane wasn’t the first glyphosate resistant weed found in Ontario, says Dr. Peter Sikkema, field crop… Read More
White mould is a fungus caused by Sclerotinia sclerotiorum, and tends to cause a bleached area of the stem, with black oblong sclerotia developing in the centre of the affected area, and inside the stem. But, we don’t want it to get that far. Enter fungicides. “The number one problem that growers have in timing fungicides is… Read More
Soybean growers could soon have access to a new tool for weed control as plans are in place to introduce varieties that are tolerant to both dicamba and glyphosate to North America in the next year or two. Dicamba tolerance will be valuable in giving farmers the ability to use multiple modes of action for weed control, particularly in… Read More
If you haven’t already applied a fungicide to your soybean acres, it may be time to consider it, as white mould and septoria are already surfacing in fields across the country. And proper timing is essential. “What we’ve seen for the most economical yield response is at that R2.5 stage, or at that early pin bean… Read More
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. As Holly Derksen, plant pathologist with Manitoba Agriculture, explains in this Soybean School West episode, there are… Read More
There are few Ontario farmers not grappling with the fallout of the May 23rd frost — corn and soybeans both have started to grow through the damage, though persistent dry conditions up until the last few days had stopped some re-growth short. Farmers also likely saw the coming weed spectrum while out scouting frost damage… Read More
