Welcome to the Bernalillo County Master Composter website. The Master Composter organization provides basic composting classes for the general public and trains volunteers to teach these classes.

And remember...when in drought, spread the compost out!

Learn About Bucket Composting

Have you heard about bucket composting with the Bokashi method? It's a method developed in Japan that is inexpensive, easy, takes up little space, has no smells, doesn't attract pests, and requires no turning. The method makes it hard to find an excuse not to compost your kitchen waste! You can compost all the kitchen scraps you normally compost as well as meat, bones, and oily things. Jill Van Nortwick recently gave a talk to BERNCO master composters about Bokashi composting. Check out these PowerPoint slides from the talk. Or, if you prefer, here is a PDF copy of the slides. The slides include a video about Bokashi composting. The video is made by a commercial company but keep in mind that you can do Bokashi composting in ordinary buckets.

If you shop at Amazon and specify Bernalillo County Extension Master Composters as your charity, a percentage of what you spend will be donated to BCEMC. It's very easy to set up.
