With increasing cases of herbicide resistance, machines designed to destroy weed seeds at harvest could be a valuable tool. But like any technology that is not yet widely adopted, there are also some lessons to be learned and challenges to overcome, as researchers with Agriculture and Agri-Food Canada confirmed last year. 2017 marked the first… 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 »
Use active math when evaluating nitrogen stabilizers
When growing corn, many farmers utilize nitrogen stabilizers to protect their fertilizer investment. Agrotain has become a popular stabilizer choice for its ability to inhibit nitrification and protect nitrogen from ammonia volatilization. There are also products that protect against losses from denitrification and nitrate leaching. AGRIS Co-operative agronomist Dale Cowan says farmers can see a yield… Read more »
Canola School: Research looking at liming to suppress clubroot
Although it’s been proven that high pH soil will not stop the spread of clubroot disease, liming has been used as a tool to curb the disease in other parts of the world. Early results from a research project underway in Alberta show raising the pH of acidic fields with lime could potentially aid in… Read more »
Wheat School: Solve your tiller problem with N, not seeding rate
Wheat tillers are nothing but a well-camouflaged weed, right? Not exactly. While excessive tillering can cause grief for fungicide timing and harvest management, one tiller can actually pull its own weight and contribute to yield. How do you best manage for one or two tillers? Say it with us now: nitrogen! If you wanted to… Read more »
Canola School: The mysterious canola flower (not swede) midge
Seven years after swede midge was identified in Ontario, three adult midge were found in Saskatchewan, in 2007. It was then believed the insects were the same species (Contarinia nasturtii), but researchers have since discovered differences between the two. “We have now behavioural evidence — we know that what we thought was swede midge in… Read more »
Soybean School: Mind your fencerows to reduce weed resistance
Are we doing enough to reduce the herbicide-resistance weed seedbank on Ontario farms? That’s a question AGRIS Co-operative agronomist Dale Cowan wants farmers in the province to consider when they’re planning their weed control programs for this year. Cowan recently attended the Commodity Classic in Anaheim, California, where he talked with farmers from Mississippi who… Read more »
Wheat School: When does your crop need spring nitrogen?
It’s late March and it’s cool in Ontario. Are you thinking about applying nitrogen to your winter wheat crop? If so, don’t mention it to RealAgriculture resident agronomist Peter Johnson – he may have a conniption. After he stops shaking, WheatPete will tell you that there is no benefit to putting nitrogen on wheat until… Read more »
Corn School: Six questions to ask before upgrading your planter
Planting season is just around the corner, but many farmers are still contemplating their planter needs for 2018. Kearney Planters service manager Shaun Dilliott says he gets consistent calls from corn growers who are making planter upgrade decisions or contemplating buying new or used planters. “One of the things we get a lot of is… 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 »
Pulse School: Root rot resistance, biofortification, and the pulse crop breeding pipeline
While yield and lodging attributes will always be critical, pulse crop breeders have placed a high priority on root rot resistance in recent years, and are increasingly focused on the nutritional profile of new pea, lentil and chickpea varieties. Tom Warkentin, pulse breeder at the Crop Development Centre at Saskatoon, joins us for this Pulse… Read more »
Canola School: New test unlocks ability to match variety resistance with blackleg type
Researchers with Agriculture and Agri-Food Canada at Saskatoon have developed a lab test for identifying blackleg disease races in canola that complements the new blackleg resistance-gene labels on canola seed. Knowing both factors — the blackleg races present in a field and the disease packages available in seed — will allow farmers to select varieties with resistance… Read more »
Soybean School: New coalition tackles growing nematode resistance
Soybean cyst nematode (SCN) is the crop’s number one yield-robbing pest, and the problem is only going to get worse as the pest continues to breakdown the defence provided by SCN-resistant soybean varieties. It really is a case of the pest becoming “resistant to the resistance,” says Iowa State nematologist Greg Tylka. About 95 percent… Read more »
Neighbourhood nutrient plans share the load to better manage manure
Your farm has a nutrient management plan, but does it include your neighbours? A larger-scale plan is a great idea for intense livestock neighbourhoods that struggle to use manure efficiently. It also ensures nutrients stay in the field and out of tiles and waterways, says Ontario Ministry of Agriculture, Food and Rural Affairs field crop sustainability… Read more »
Soybean School: Cutting back harvest losses at the header
Even for seasoned soybean growers, harvest losses happen, and it’s estimated 80 percent of harvest losses occur at the header with soybeans. At $11/bushel, getting a few extra bushels off each acre adds up quickly. Just how losses are affected by combine header design and harvest speed was the subject of a two-year study by… Read more »
