Checking on the Compost

When we checked the composters, we found a number of worms in the biochar composter were congregated around its rim and lid, while the ones in the other composter had not. We speculated that the worms were attempting to escape contact, at least temporarily, with the biochar. Perhaps the biochar created an unfriendly environment for them. We decided to leave them alone and see what happened. Within a month, they had apparently returned to the composting materials and we noticed no more unusual worm behavior. We turned the compost in the containers one time during the next four months.

Making the Compost

The Compost Team filled two Earth Machine composters (also known as “Darth Vader” composters) with composting materials. Some 100-200 earthworms were also added to each composter. Five gallons of biochar was mixed into one of the composters.

Approving the Budget

The Douglas County Master Gardeners’ Executive Board Committee approved the Biochar Demonstration Project materials budget.

Obtaining the Biochar

A five-gallon bucket of biochar (approximately .67 cu. ft.) with a known chemical profile was obtained from a local source.
