There are several ways to measure the costs and benefits of crop rotations. Weed population changes, soil organic matter building or depleting, yield bumps or total energy used are all different ways of gauging the relative advantages of different rotations. Dr. Perry Miller, professor at the University of Montana, has done extensive work into crop... Read More

In part 1 of our conversation with Dr. Hugh Earl of the University of Guelph he talked about the impact water stress can have on soybean yields. That study suggested that at some point during a number of growing seasons, even if rainfall was adequate, some yield was being lost to water stress. One of... Read More
It can seem like an efficient way to solve two problems at once — add an insecticide in with the fungicide on canola and, voila, all your pest troubles go away. But not so fast. While applying an insecticide when pest insect levels are at or above threshold may be the right move, adding an... Read More
If ever we needed a new curse word, let me humbly suggest kochia. If you thought it was tough to kill before, it's quickly becoming even more difficult. As Clark Brenzil, provincial weed specialist with Saskatchewan Ministry of Agriculture, explains, not only should kochia be taken off the label of every Group 2 herbicide, it's... Read More
It sounds a little out there — plants talking to each other, warning them to arm themselves against predators and biotic stress, but it's real. The research into plant communication is actually decades old, but for some time it was largely ignored by the research community. That is, until now. Rob Saik, president of the... Read More
There's generally always enough moisture metered out through the growing season to finish the soybean crop, but soybeans can soak up a lot of water and translate that into yield if it's there. But by how much? What are we really losing to drought stress? Dr. Hugh Earl of the University of Guelph and colleagues... Read More
Ever wonder what the Canola Council of Canada does and who is involved? RealAgriculture.com caught up with Patti Miller, president of the council, to ask her those questions and many more. For example, 2012 was in some ways a fantastic year for the crop — a huge number of acres went in and planned crush... Read More
Proper tank clean-out is a key aspect of avoiding herbicide injury, but the waste water created from tank cleaning needs to be handled responsibly to avoid unwanted plant injury or water contamination. Using a biobed — essentially a clay-lined, dedicated area rich in microbes where tank water is emptied for further degradation by microbes —... Read More
Steve Laroque is starting to see some significant differences on his farm north of Drumheller, Alta., after three consecutive years of practicing controlled traffic farming. After learning some hard lessons in the first few seasons — their measurements were off when setting up a hitch for inter-row seeding — 2012 offered a glimpse at some... Read More
The 2013 wheat midge forecast map is now live on the Alberta Agriculture website, Ropin the Web. This forecast is based on 298 soil samples taken in the fall after harvest. Indications are that wheat midge will be more of a concern for 2013 than it was for 2012. Midge numbers have increased and they... Read More
