Reference number : GC-2017-Q2-04363, amendment number : , agreement type : G, recipient legal name : Jabaji, Suha (McGill University)|Jabaji, Suha (Université McGill), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : PROBLEM: Van Luyk Greenhouses and Garden Centre, uses soilless growing media for growing and_x000D_
maintaining plants in containers. When plants are transplanted or harvested, the spent growing media are_x000D_
directed to landfills. Around 24% of the spent soilless mix which amounts to 1/4 truckload is directed to_x000D_
landfills. In the company's greenhouse plant production activity, 3.5% of the cost of materials is spent on_x000D_
purchasing soilless mix which amounts to about $ 20,000/year. As a consequence, only 75% of the soilless_x000D_
substrate is sold with container plants to customers. Thus, the Company's motivation is to prevent this waste_x000D_
and be able to recycle and reuse the spent substrate. This approach is economically sound by reducing costs of_x000D_
materials and of disposing it. Greenhouse industry in general could economically benefit by recycling spent_x000D_
soilless mix which protects our environment._x000D_
OBJECTIVE: The proposed collaboration with McGill arises from the need of the industrial partner, to test_x000D_
crop response to the cultivation in spent soilless potting substrate, and to characterize and re-optimize its_x000D_
physical and nutrient properties so the spent potting mix will perform equally well as the original virgin potting_x000D_
mix._x000D_
BENEFITS: Improvement of nutrient efficiency, physical and biological stability of spent soilless mix in_x000D_
horticulture is a research priority for sustainable production and environmental reasons. Knowledge acquired_x000D_
through this study about physical, chemical and microbial properties of the soilless mix before and after_x000D_
planting cycle will help the company make decisions and implement soilless media recycling procedures_x000D_
