The South Saskatchewan River Watershed Stewards are excited to be building a biobed with the Meewasin Valley Authority. With the support of an environmental grant through the city of Saskatoon, a biobed will be built for use by the Meewasin Valley Authority and city staff.
What is a biobed? It is a mixture of soil, compost, and straw that absorbs pesticide rinsate and then microbes living in this mixture degrade the rinsate. This reduces the environmental impact of cleaning locations. They can be as elaborate or as simple as you like, with a variety of options depending on your budget and construction preferences. Currently biobeds as being used by Environment Canada, Agriculture and Agri-Food Canada, Rural Municipalities and chemical companies.
Research conducted by Agriculture and Agri-Food Canada (AAFC) demonstrates a biobed system has the potential to provide effective management of sprayer rinsate. AAFC data from pilot sites show the biobeds are operating well and are removing more than 95% of the pesticides from the rinsate. If the rinsate is run through a series of two beds, up to 100% of the pesticide is removed. An operation/maintenance manual will be available soon.
If you are interested in building your own biobed, call the SSRWSI for more information!
