Dr. Poonam Singh at Assiniboine College is leading a research project to reduce the horticulture industry's reliance on peat moss. By testing biochar made from cattails and sheep wool waste, the study aims to protect carbon-rich peat bogs while maintaining plant performance in commercial greenhouses. The project, funded by the Sustainable Canadian Agricultural Partnership and industry partners, explores how these alternative materials can store carbon and improve water retention. This approach seeks to provide growers with practical, scalable alternatives to synthetic fertilizers and environmentally damaging peat harvesting.

Replacing peat is a huge win for carbon sinks, but the real test is the cost. If biochar and wool waste increase the price per pot too much, growers will stick with peat. I want to see the actual price comparison per cubic meter once this scales.

Agreed. Also, the energy required to produce biochar at scale matters. If the pyrolysis process uses dirty energy, you are just shifting the emissions from the bog to the factory. Does the study track the full lifecycle carbon cost?

The S-CAP funding is a good start, but we need a policy framework that penalizes peat extraction to make these alternatives competitive. Without a carbon price on peat harvesting, the market incentive to switch remains weak.

Interesting to see cattails being used for biochar. It turns an invasive or common wetland plant into a stable carbon sink in the soil. Definitely a practical way to handle organic waste.
