Excerpt:

The Biomass Production Laboratory at McGill University, with support from Urban Barns, is paving the way for research in urban agriculture. Recent innovations with Light Emitting Diodes (LED) as a plant energy source, has brought about this new area of research. LED lighting systems have the capability to control wavelengths emitted. This allows for research on the impact of different spectral wavelength combinations on plant growth and development. Compared to conventional lighting techniques when growing tomatoes, an arrangement of red and blue lights has proven to increase growth, improve morphology, and suppress plant pathogens.

“We’re here in an urban environment on smaller scale so we need to maximize our space and extend the growing season to have some income coming in the door year round,” said Tyler Brown, farm manager at Real Food Farm.

Excerpt:

VANCOUVER — New Vancouver Park Board guidelines will require that edible plants grown in community gardens and agricultural projects be planted in soil free of urban contaminants.

New soil and barriers must be used where the quality of the existing soil is not known, and the Park Board will ensure that affordable soil testing will be available to growers, according to a draft of the new Urban Agriculture Policy expected to be approved later this month.
