Reading Time: 5 minutes It’s been more than a few years since drones made their debut in agriculture, but questions about whether they’re worth producers’ time aren’t going away. Most agricultural drones are set up to measure canopy reflectance using the normalized difference vegetation index (NDVI), a graphical indicator that assesses crop health by measuring canopy reflectance. Drones carrying […] Read more
A drone spots a problem in your field. Now what?
Drone-mounted cameras measuring NDVI reflectance can identify crop problems, but not necessarily the cause. Researchers are looking for other tools that might
Farm like Scrooge
A long-term study suggests that penny-pinching can actually help the bottom line
Reading Time: 4 minutes Agriculture and Agri-Food Canada research scientist Bruce Gossen says the 18-year study was boring, but its results weren’t. Gossen and his colleagues took a long-term look at the effects of cropping diversity and inputs at Scott, Sask., from 1996 to 2013, but they didn’t just evaluate yields. They also looked at disease, insect and weed […] Read more
The U.S. ‘No. 1 weed problem’ heads north
Other weeds are higher priority for now, but be on the lookout for Palmer amaranth
Reading Time: 4 minutes It can grow two to three inches per day and reach eight feet tall. Each plant can produce more than a million seeds that can emerge right through the growing season. It has reduced yield up to 91 per cent in corn and 79 per cent in soybeans. It’s resistant to glyphosate and multiple other […] Read more
PHOTOS: How to identify Palmer amaranth
Reading Time: < 1 minute The amaranth species look fairly similar as seedlings. Nobody wants to wait until they’re in seed to figure that out. When in doubt, ask an agronomist.” — Tammy Jones, Manitoba Agriculture. For the latest information, visit the North Dakota State University website.
Avoiding another year of ‘snirt’
North Dakota farmers and researchers are finding success in controlling soybean field erosion by planting cover crops
Reading Time: 5 minutes “Snirt” became a buzzword in Prairie agricultural journalism in 2017 and 2018, and for good reason: the dirty snow lining ditches along highways was a telling indicator that there had been a soybean field there last season. It’s a problem across the Red River Valley region in particular, where soybean producers are used to tilling […] Read more
Nutrient balance key to avoiding sulphur deficient soils
Production of more high-sulphur demand crops such as pulses and canola is creating a shortage in some fields
Reading Time: 4 minutes In order for any crop to use fertilizer efficiently, it needs to have all of its nutrient deficiencies met, says Miles Dyck, an associate professor of soil science in the department of renewable resources at the University of Alberta. The most common nutrient deficiencies in Western Canada are nitrogen and phosphorus, but because of the […] Read more
Tillage erosion costing farmers billions
The pressure to get an early start on newer crops such as corn and soybeans encourages tillage practices which may not be sustainable
Reading Time: 5 minutes This past spring was one of the worst on record for so-called “snirt,” or dirty snow, in ditches across the Prairies — a sign that wind is moving loose topsoil to the margins of fields. While snirt is an indication that fields are susceptible to wind erosion, however, University of Manitoba soil science professor David […] Read more
Another item to put in rotation
A new tool can determine which blackleg genes are in a field, allowing growers to choose a variety that will prolong the life of their resistance genetics
Reading Time: 3 minutes A new tool will help western Canadian producers implement “educated rotations” to prolong the utility of blackleg resistance genes in canola, says Dilantha Fernando, a plant science professor at the University of Manitoba. Blackleg is on the upswing in Canada. According to canola researchers, blackleg resistance is starting to break down due to a combination […] Read more
Protect your midge-tolerant wheat
The midge-tolerance gene was found in the majority of SWS wheats in 2017. Refuge seed is required to keep this trait in play
Reading Time: 3 minutes Producers should add refuge seed to most Canada Western Red Spring (CWRS) and Soft White Spring (SWS) wheat varieties in 2018 to prolong the longevity of the midge-tolerance Sm1 gene, says Todd Hyra, western business manager for seed marketing agency SeCan. Last spring, Canadian researchers discovered Sm1 in most SWS varieties, including AAC Indus, AC […] Read more
Growing potatoes without chemicals
Organic potato production on a commercial scale is a challenge, but one Ontario grower is meeting it
Reading Time: 4 minutes Isaiah Swidersky offers a careful answer when asked if organic potato production is a risk worth taking. “To some degree it is, but there’s a reason I haven’t expanded it to 200 or 300 acres,” Swidersky says. “It’s a challenge to grow organic potatoes. But I’m optimistic. It’s a good challenge.” Swidersky’s operation, Rose Mountain […] Read more
