An analysis of 27 years of herbicide evaluation trials from 1992- 2018 found that when weed control was less than 94 per cent over the entire weed community and growing season, it exacerbated the effect of heat or drought on corn yields.

Weeds may compound effects of climate change impact

Study says corn yields are expected to be reduced as weeds compete for fewer water resources in the American Midwest

Glacier FarmMedia – A U.S. study has found that weeds will likely deepen the negative impact of climate change on corn yields, says a scientist. Such results likely extend to other crops, said Marty Williams, an ecologist with the U.S. Department of Agriculture.  “I think what this tells farmers is that going forward, more than […] Read more

Activists are encouraging a new global treaty encouraging plant-based food.

International campaign calls for end to food animal use

Plant Based Treaty initiative asks national governments to transition away from food animal production

Glacier FarmMedia – Environmental and animal rights activists have launched an international campaign to halt what they see as the harmful impact of meat, dairy and egg farming on the world’s climate due to methane emissions. They urge world leaders to negotiate a proposed Plant Based Treaty to begin the transition to food systems that […] Read more


Polycropping, such as this crop of peas and oats, is seen as one of the tools Canadian producers will have to adopt as a way to turn agriculture into a net carbon sink for emissions by 2030.

Carbon sink efforts in a race against time

Industry has less than 10 years to make major technological changes as it attempts to meet emission reduction targets

Glacier FarmMedia – It’s theoretically possible to turn Canadian agriculture into a net carbon sink for emissions as early as 2030, but producers would have to quickly overcome numerous challenges, says a researcher. “We’re at the edge of a cliff,” said Joy Agnew, associate vice-president of applied research at Olds College in Alberta. “We need […] Read more

Farmers in Canada are concerned that the carbon tax will make them less competitive in the global marketplace.

Farm groups form carbon coalition

The potential of much higher carbon taxes has caused concern

Glacier FarmMedia – Proposed federal carbon tax hikes seen as a threat to farmers have prompted the formation of a national coalition to oppose the carbon plan. “I think it raised a lot of concerns for how farmers would disproportionately be impacted because of their reliance on fuel and on natural gas to feed Canada […] Read more
