Weed survival can be predicted via imagery
Researchers using imagery to predict viability of Palmer amaranth
Researchers are putting imaging technology to work to improve weed management practices. Maor Matzrafi of the department of Plant Sciences at the University of California, Davis, has been evaluating the use of hyperspectral imaging technology to assess germination and herbicide response in Palmer amaranth. Why it matters: Weed resistance to glyphosate, a broad spectrum herbicide, […] Read more
SWAC 2019 conference: The Road Ahead
What to see and look for at the 2019 Southwest Agricultural Conference
Producers attending the 2019 Southwest Agricultural Conference will have their agronomic and farm business mind stimulated. The conference, with the theme: The Road Ahead is coming to the University of Guelph’s Ridgetown Campus on Jan. 3-4. Speakers will share the latest on topics ranging from nutrient management to marketing, compaction to pest management, precision agriculture […] Read more

Can it pay to stop farming unproductive land?
Taking underperforming areas of a field out of production can support farm profitability and conservation, say researchers
Can some farmers increase their profitability by not working underperforming parts of the field? Researchers at the University of Guelph think so. According to those researchers, combining conservation with crop production on a field-by-field level can better serve both the environment and producers’ bottom lines. Why it matters: Consistently underperforming areas of a farm hurt […] Read more

Project to fund 2000 acres of cover crops
The Upper Thames River Conservation Authority (UTRCA) has announced that the Canadian Agricultural Partnership has granted $500,000 for UTRCA staff and local certified crop advisors to work closely with landowners and plant cover crops within a subwatershed of Medway Creek. The upper Medway Creek watershed will host this project over the next three years. UTRCA […] Read more

Making technology work for healthier soil
Farmers have to make decisions on which soil-health technologies they want to adopt
Building and maintaining soil health increasingly involves technology. The challenge for farmers is deciding which approach they invest in to monitor and maintain their soil health. Three different approaches using technology to solve soil health problems were presented at the Grey County’s third annual Ag 4.0.2 conference held Nov. 1, 2018 in Meaford. Why it […] Read more

Evaluating cover crops for the long term
Too early to assess corn and wheat yields, but the benefits to tomatoes already seem clear
It’s widely recognized that cover crops boost soil organic matter, but their long-term agronomic and economic benefits are less well understood. Researchers at the University of Guelph’s Ridgetown and Elora campuses have undertaken some long-term studies to identify the impacts of cover crops in some growing conditions and management styles common to southwestern Ontario. Why […] Read more

Cover crops help reverse soil organic matter loss
The benefits may not show up immediately so farmers need to be patient
In Ontario, where the loss of soil organic matter is a long-standing problem, cover crops and other cultivation strategies designed to improve soil structure are playing an increasingly important role in cropland sustainability. However, a variety of factors are limiting how quickly Ontario farmers are adopting cover crops, even as soil organic matter in the […] Read more

OMAFRA strip till demo to highlight working units
The live demonstration gives farmers a chance to see strip till machines in the field
OMAFRA is taking soil health action to the field this year at Canada’s Outdoor Farm Show (COFS). The Ontario Ministry of Agriculture, Food and Rural Affairs is hosting a live strip tillage demonstration every day at 11:15 a.m. in the Southwest Demo Field at the show. This is in addition to the regular equipment demonstrations […] Read more

Waterjet use on planters eliminates coulter-soil contact
Aquatill concept remains in testing phase, but may offer options for no-till farmers
The use of pressurized water as a cutting tool has come full circle. It was used extensively to power away earth during the 1850s California Gold Rush. Now, after being adapted and refined to carry out high-tech, precision cutting of metals and other industrial materials indoors, the technology has turned back to the ground. Why […] Read more

Mapping profit can drive precision-farming decisions
Precision farming can find the high yield and low yield, high fertility and low fertility areas of a farm, but the missing link has been how that ties to profitability. Why it matters: The capacity to apply nutrients variably across a crop field isn’t new, but it’s been difficult for farmers to see the justification of […] Read more
