Finding the right light to grow better plants – on Earth and in space

By Lilian Schaer

Guelph – It’s an unremarkable building from the outside, tucked away on a side street on the University of Guelph campus. What’s inside, though, is most remarkable – and may well be lighting the way for future human life in space, as well as better life here on earth.

Not only are researchers in the Controlled Environment Systems Research Facility working on how to best grow food away from Earth, they’re also experimenting with using light to improve the production of medical marijuana and cancer-fighting tobacco plants, helping nurseries reduce water and fertilizer use on their trees and shrubs, and finding low cost solutions to growing more compact bedding plants.

PhD candidate Dave Hawley is using basil and strawberry plants in experiments designed to find the best LED light combination for use in small, low atmosphere growth chambers that will not only simulate but actually improve upon real sunlight – and resulting in better flavour and ultimately helping feed people on long space journeys.

Navigating Northern Ontario’s climate shortcomings

Weather Station 2 - webBy Lisa McLean for AgInnovation Ontario

North Bay – Farmers in Northern Ontario have a short growing season. There’s little room for error, and every bit of data helps.

That’s why for the past seven years, a research team has built a tool that gives both real-time and historic information that helps growers make more informed crop management decisions.

The project, called GeoVisage, is the brainchild of three Nipissing University researchers – geographers Dan Walters and John Kovacs, and computer scientist Mark Wachowiak.

The team says the project was born from a request from area farmers to collect data that could be shared with farmers in a timely way on their own farms.

“Initially the idea was to collect quality information that could be shared among Northern Ontario farmers without requiring them to meet in person all the time,” says Kovacs. “Our area saw a shift from cattle to cash crops about ten years ago, and farmers needed enough data to decide what different types of cash crops made sense to grow.” Continue reading

Sunny days: New tool helps greenhouses make light of winter

Per Aage Lysaa - webBy Lisa McLean for AgInnovation Ontario

Guelph – Each year, Canadian greenhouse growers face a challenge nearly as old as the sun itself: During the darker days of a Canadian winter, nothing grows.

Greenhouse production enters a mandatory hiatus, because there is not enough sunlight to sustain plant growth. Facilities are cleaned out. Plants are replanted.

And when the first harvest of the new season finally arrives, Canadian growers must battle for space on supermarket shelves, where produce from warmer climates has enjoyed its day in the sun.

Now, a systems integration company with facilities in Norway, China and Canada is offering a solution to Canadian greenhouse growers: LED lighting systems that can augment the sun’s rays, even when sunshine is scarce. Continue reading

Identifying healthier trees for greener Ontario highways

Test trees web By Lilian Schaer for AgInnovation Ontario

Niagara Region – Trees and shrubs growing next to busy roads and highways need a special kind of resilience to thrive.

In addition to handling Canada’s cold winter and hot summer climate, they have to be able to survive without after-planting care or irrigation, which means landscapers have to select species very carefully.

To better understand how to create urban plantings that mimic natural systems when it comes to retaining moisture, root shading, and protection from environmental stresses, nursery and landscape experts at Vineland Research and Innovation Centre have designed two experimental test planting sites.

Automated weather alert system helps tender fruit farmers mitigate winter damage

A new website is helping tender fruit growers monitor the cold hardiness of their buds over the winter months and manage possible winter injury.

Growers can register on www.tenderfruitalert.ca to receive free email alerts about potential low temperature situations that can help them make decisions about when they should use tools like frost fans and wind machines to protect against the weather.

The online, automated weather alert system was launched by Ontario Tender Fruit as part of a project funded through Growing Forward 2 so growers can better mitigate climate-induced damage to their orchards and crops. Ontario’s tender fruit crops include peaches, nectarines, cherries, apricots, and plums. Continue reading
