Water on app New app to reduce water use for Canada’s ornamental plant sector

Jared Stoochnoff

Guelph – It takes a lot of work – and a lot of water — to grow healthy trees and shrubs for Canada’s ornamental plant sector. The industry, which boasts approximately 3,500 nurseries across Canada, uses an estimated 190 million cubic metres of water every year.

But new research suggests this is two to three times more water than healthy trees need. And soon a new tool will be available to help nursery managers determine when to turn on –and turn off – the hose.

Jared Stoochnoff, a University of Guelph graduate student in the School of Environmental Sciences Controlled Environment Systems Research Facility, is pioneering a new irrigation management strategy designed to reduce water consumption and mitigate the environmental impact of ornamental nursery operations.

“Because many nursery irrigation managers lack reliable ways to quantitatively predict a plant’s actual water requirements, they tend to err on the side of caution and overwater,” Stoochnoff says. “This results in unnecessarily high water and fertilizer run-off that negatively impacts local watersheds.” Continue reading

Sky high scouting zeros in on crop stressors

Using drones, farmers can save money and increase their crop yields by mapping their fields to identify areas of stress.

By Jane Robinson

Peterborough ON – What started as a move back to the Ontario family farm for Norm Lamothe turned into a big move forward in crop scouting technology for Canadian farmers.

Lamothe left a 10-year career in the aviation industry to return to be the sixth generation on the family farm near Peterborough. At the encouragement of a neighbouring farmer, Lamothe bought his first unmanned aerial vehicle (UAV) or drone in 2015. He had a small group of area farmers already signed up to have a block of acres viewed by the new technology and help share the investment risk.

“We quickly identified the opportunity for farmers to save money and increase their crop yields by mapping their fields to identify areas of stress,” says Lamothe. Continue reading

GreenTech keeps coffee hot, but not too hot

Peterborough – When the World Health Organization (WHO) issued a warning in 2016 about the connection between drinking very hot beverages (above 65 C) and esophageal cancer, researchers at Trent University had an unlikely solution: soybeans.

Within months, they developed a travel mug that uses a unique soy-based material inside its walls to cool beverages to safe temperatures within minutes, and maintain the temperature in a perfect range for several hours.

Dr. Suresh Narine, professor in Physics, Astronomy and Chemistry who also heads up the Trent Centre for Biomaterials Research (TCBR), has been experimenting with energy storage properties in lipids. He says the research team developed the material in response to a challenge: how to use biomaterials to store energy, and control how that stored energy gets released.

“We figured out how to design materials that melts or crystallizes at specific temperatures,” says Narine. “It stores the heat when it melts, and when the material crystallizes, it gives that heat back.” Continue reading

From waste to wealth: transforming greenhouse waste into energy

Animesh Dutta

By Jane Robinson

Guelph – When Animesh Dutta ponders the problems of the world, he lands on energy security, food security and climate change. The University of Guelph researcher’s latest project holds promise for addressing all three.

As professor and director of the Bio-Renewable Innovation Lab in the School of Engineering, Dutta focuses on taking waste from farms or food processors and finding the best solution to convert it into renewable energy that will maximize the economics.

When he started working on bioenergy, Dutta saw the benefits of creating a renewable source of energy that didn’t interfere with food production.

“The economics don’t seem to be there for using feedstock for bioenergy,” he says. “You have to purchase the raw product and farmers want a price for their biomass crop that is higher than the value of the bioenergy it makes.” Continue reading

Fine wine grapes take time

Wine grape trials show promising early results

By Lisa McLean  

Vineland, Ontario – When Dr. Helen K. Fisher retired as viticulture research scientist at Vineland Research and Innovation Centre (Vineland), there were a few loose ends to tie up.

Namely, what to do with her research on advanced wine grape selections for cold climate wine growing regions.

“Breeding work for wine grapes is a very slow process,” says Fisher. “Not only are you trying to find a plant that fits a climate, but it also needs to fit into a wine profile wineries are looking for.” Continue reading
