Converting excess woody biomass to a valuable soil amendment

Saturday, June 30, 2018 | San Juan Island

Biochar, a soil amendment made from woody biomass like branches and small-diameter trees, presents an opportunity for landowners to convert forest thinnings to a high-value product. Removing excess biomass from dense, crowded San Juan forests is an important way to increase fire resilience and improve ecological health. This workshop will cover all the tips and tricks San Juan County landowners have discovered to successfully and safely manufacture optimal biochar.

This workshop is the third in a three-part series on woody biomass in the San Juans. All forest owners are encouraged to attend!
