Soil tests are one tool for determining fertilizer needs of a particular field, but several other factors impact the overall productivity of any soil zone, regardless of nutrient level. Factors such as physical make up of the soil, salinity, internal drainage, field position, and organic matter levels, all play a role in determining the high-yield… Read More

Last year at the World Agri-Tech Innovation Summit, investors and inventors were all a-buzz about biologicals. This year, the spending mood at the conference was more subdued overall, with the focus shifted away from biological products and on to measuring carbon emissions. Jay Whetter, editor of Canola Digest and unofficial San Fransisco tour guide, attended… Read More
Cover crops can be a non-starter in dry areas of the Prairies — or are they? A lack of moisture is definitely a concern when working to establish cover crops; however, over the long term, farmers Derek and Tannis Axten of Axten Farms at Minton, Sask., are finding covers build soil water holding capacity. That’s… Read More
When it comes to improving fertilizer application and utilization, growers are encouraged to focus on the 4Rs — the right source, right rate, right time, and right place. Former Manitoba Ag soil fertility specialist John Heard won’t argue with that strategy but he would also like farmers to think about the ‘4Ls’ — lift-off, leftover,… Read More
For years, even decades, one crop’s boost in productivity because of following a different crop was put down as the “rotation effect.” As we begin to unravel what the rotation effect actually is, it’s clear that rooting depth and type, root exudates, and microbial population shifts all play a role in contributing to the bigger… Read More
Pop quiz: does water vapour insulate, and do cover crops cost yield? The answers: yes, and sometimes. To dive into to how cover crops might cost in yield potential but still save fuel, Peter “Wheat Pete” Johnson kicks off another episode of the Wheat Pete’s Word podcast. Also on the episode: how a milder winter… Read More
Biological products, such as inoculants for pulses and soybeans, have been around a very long time, but the ever-expanding world of biological products now means that growers have options for hundreds of products that are supposed to do everything from stimulating root growth, to helping plants recover from hail, to fixing nitrogen. To help evaluate… Read More
Biologicals hold great promise for improving crop production. From increasing root activity, soil microbes, and nutrient availability to building plant resiliency to abiotic stresses — this emerging crop input segment is bursting with product choices. But for farmers, selecting which product and application is right for their acres can be a daunting and confusing task…. Read More
Cover crops are not magic. It’s important to first understand the goal of using a cover crop and then measuring up each species and season to see if it’s a match. Farmers from east to west are using cover crops to accomplish several things: reducing erosion, cycling nutrients, fixing nitrogen, and fighting weeds, but that… Read More
Sweat the details and practice, practice, practice. It may sound like gridiron football strategy but it will also make farmers winners in the battle to improve soil health, says North Dakota-based independent agronomist and crop consultant Lee Briese. When it comes to improving soil health there are plenty of fixes — from reducing tillage to… Read More
Compared to 2014, a kilogram of beef in Canada is now produced with 15 per cent fewer greenhouse gas emissions. According to the National Beef Sustainability Assessment (NBSA) and Strategy report, the Canadian Roundtable for Sustainable Beef (CRSB) says this latest assessment reflects three years of scientific analysis to make the determination, comapring 2014 to… Read More
Diversity pays dividends in crop production but researchers, agronomists and farmers really don’t have a good grasp of how and why different crops impact each others in the rotation. University of Guelph crop researcher Dr. Dave Hooker is never shy to champion more diverse rotations. Research from long-term trials at the University of Guelph’s Ridgetown… Read More
Healthy soils can be a crops’s best friend when the weather turns extreme. If it’s too dry, a healthy soil with high water-holding capacity can capture, store, and deliver critical moisture to growing plants; if it’s too wet that same soil will play a key role in transporting excess water down through the soil profile… Read More
Precision Planting is changing the process of testing soil with a new Radical Agronomics program that relies on an automated soil analysis laboratory. Mike Easter, Precision Planting’s commercial lead for Radical Agronomics, says the program is designed to address some challenges with current laboratory systems and soil testing’s manual process. “What we’ve done is we’ve… Read More
Western Canadian soils are generally neutral to slightly basic in pH values. On average, there’s plenty of buffering capacity to the soil in the west but that doesn’t mean there aren’t pockets of acidic conditions. What’s more, research is proving out to show that long-term zero-till combined with applied fertilizers is creating an acidic area… Read More
