Giant Ring of Fire Kiln Eats Smoke

We used 5 sections of sheet steel (44" x 86" with 2" flanges) bolted together to surround a large slash pile. All the combustion air comes in from the above. This counter-flow combustion pulls smoke down into the flame where it burns for clean combustion. At the end, we quench with water and make biochar

upcoming events

February 27-28: Biochar Workshop near Tualatin, OR - FREE

Learn how charred biomass (biochar) can increase soil productivity, reduce wildfire risk, and slow climate change. In a morning classroom session on Feb 27, biochar consultant Kelpie Wilson will present biochar basics and the science of biochar production. USDA ARS researchers (Kristin Trippe, Manuel Jaramillo) will present their Biochar Atlas decision support tool for biochar applications and discuss recent field trials using biochar in vineyards and other applications.  The afternoon session will take place at the David Hill Winery where Kelpie Wilson will demonstrate on-farm applications of biochar for making compost from farm waste, manure management in barns and the production of bokashi – a fermented organic fertilizer made from biochar and farm wastes. We will reconvene at David Hill Winery on Feb. 28 for a full-day demonstration of methods for producing biochar from vineyard prunings using small biochar kilns and biochar pile burning techniques. Register here to reserve your space.

February 29: Biochar Workshop in Corbett, OR - FREE

 East Multnomah Soil and Water Conservation District is sponsoring a Free Biochar Workshop with Wilson Biochar Associates on February 29th, 2020 from 9:00am - 4:00pm.

Registration required. Go to to reserve your space, or call: (503) 935-537

March 7-8: Biochar Course at Siskiyou Field Institute

During this two-day workshop you will learn how charred biomass (biochar) made from non-merchantable woody residue left from logging and pruning operations can increase soil productivity, promote beneficial soil microbes, reduce wildfire risk, decrease emissions, and slow climate change.  Mechanical engineer Kelpie Wilson and forest ecologist Ken Carloni will give an overview of the history and science of biochar production and use during classroom presentations.  In the afternoons, we’ll explore small to large-scale biochar production theory and practice.  On Day 2, we’ll apply that theory in a hands-on demonstration of loading, firing and quenching in a variety of kilns for producing biochar in the field. Siskiyou Field Institute  is located at the Deer Creek Center, 1241 Illinois River Road, Selma, OR 97535
