As part of a study in sustainable greenhouse waste management, a growing medium component made from composted greenhouse waste was investigated and compared with the conventional sawdust growing medium used in most vegetable greenhouses in British Columbia, Canada. The compost provided higher moisture retention and density, and lower porosity; for optimal growing conditions, irrigation should be adjusted to take this into account. In a commercial tomato greenhouse trial setting, a mixture of 2:1 sawdust to compost by volume was found to be suitable as a growing medium, providing similar yield, crop health and fruit quality, and additional pH buffering compared with the conventional system. Since the waste processing is carried out on site, quality and consistency of the compost can be ensured. Successful application of compost in the growing medium can help provide a more sustainable waste management strategy through on-site recycling and conservation of organic resources, and may offer the grower disease suppression benefits.
