Glyphosate resistant waterhemp has spread from Essex Country, Ontario, all the way to Leeds-Grenville County, nearly 700 kilometres away in just seven growing seasons. While the exact path of spread is not known, Dr. Peter Sikkema, weed management professor with the University of Guelph, says that introduction can be through wind dispersal, in livestock feed, or… Read More

Long-term field research, conducted by the University of Guelph, has confirmed Solvita Soil Tests as valuable testing tools for evaluating soil health. Research results show that Solvita tests enabled a high level of certainty in “useful” cropping comparisons and correlated with soil carbon levels and total soil nitrogen. Solvita tests have the ability to capture… Read More

When glyphosate-resistant waterhemp was first discovered in Lambton County in 2014, University of Guelph weed scientist Peter Sikkema never imagined the course the weed would take across Ontario, or the speed it would travel. In 2020, Sikkema and his team collected seeds in Leeds & Grenville County. “So that means glyphosate-resistant waterhemp has moved 700… Read More

Originally set to be released in early 2020, but delayed because of the COVID-19 shutdown, a joint report between University of Guelph and Dalhousie University sets a path forward for Canada’s “ailing” dairy sector. Co-authored by Sylvain Charlebois, director of the Agri-Food Analytics Lab at Dalhousie University, Jean-Luc Lemieux, and Simon Somogyi, Arrell Chair in… Read More

A team of researchers at the University of Guelph are studying why Canadian baristas sometimes have problems foaming milk for their customers’ lattes, and it starts with on-farm milk handling. Dr. David Kelton, Dairy Farmers of Ontario Dairy Cattle Health Research Chair, graduate student Hannah Woodhouse, and animal bioscience undergraduate student Mikayla Ringelberg are studying… Read More

Dairy calves experience many challenges in early life, and producers need to be diligent in the hours and days after birth to ensure calf health and reduce mortality. Overall, research shows that eight percent of calves die within 48 hours of birth — this includes those born dead or those that die within the first… Read More
