Bernalillo County Extension Master Composter Program
Welcome to the website of Bernalillo County Extension Master Composters. BCEMC operates in the high desert of central New Mexico, USA. This includes Albuquerque, Rio Rancho, nearby counties, communities, and Native American pueblos. Our climate and weather significantly impact our composting practice. Our elevation is about 5000 feet above sea level. We have four distinct seasons. In the summer, we have frequent drying winds and intense ultraviolet radiation. We receive about 9 inches of precipitation annually. An important objective in any home composting setup in our area is to manage moisture.
The Master Composter organization provides basic composting classes for the general public and trains volunteers to teach these classes.
- If you would like to attend a free composting class, please see Classes and Other Activities for the Public.
- If you would like to schedule a composting class for your organization, see Contact Information.
- If you would like to become a master composter, see Master Composter Volunteer Training.
- If you have a composting question, please see Ask a Master.
- If you would like to know more about us or find composting resources, see additional links in the left sidebar.
And remember...when in drought, spread the compost out!
If a Class You'd Like to Take is Canceled ...
Due to coronavirus restrictions we have had to cancel many classes. We will work to reschedule them whenever we are able. In the meantime, please feel free to email us your questions and learn more about composting using the links to resources in the left-hand column of this page. Now is a good time to start a compost pile in your backyard or a bokashi bucket in your kitchen.
It Is Safe to Compost During the Covid-19 Pandemic
Some have asked:
- Can I continue to compost at home during the pandemic? (Yes!)
- What about the leftover food that might have been coughed or sneezed on?
- Can I continue to put my used tissues in my compost?
- Are there extra precautions I should take?
For answers to these questions, please see Frequently Asked Questions about Residential Composting during the Covid-19 Pandemic from the US Composting Council.
It's Our 10th Anniversary Year!
The Master Composter program began in 2010 as a program of the Bernalillo County Cooperative Extension Service. The first Master Composter Volunteer Training commenced on April 24, 2010. We formed the BCEMC Association on October 20, 2010. During these ten years, Master Composter volunteers have shared high desert home composting information with the public through free classes and information tables and workshops and a question and answer email hotline and brochures and demonstration sites and these web pages. We continue to hear from more and more people who are interested in learning about the various methods for composting at home and hope to continue this service for many years to come.
Backyard Composting Series Posponed at Gutiérrez-Hubbell House
Our workshops at the Gutiérrez-Hubbell House has been postponed until further notice. We hope to start them again as soon as we no longer need to be isolated. Check Gutiérrez-Hubbell House Backyard Composting Series for updates.

What Causes Compost Fires and How Can We Prevent Them?
In the summer of 2018, Albuquerque experienced a large fire in a commercial composting facility caused by spontaneous combustion of the compost. Spontaneous combustion in home compost piles is rare. However, the dramatic fire in Albuquerque inspired us to provide some information about the conditions that might lead to such a fire and how to prevent one. See Spontaneous Combustion in Compost.
See Our Presentations on Homemade Compost Bins
Please check out our presentations for four types of compost bins you can make at home that are especially suited for our desert climate.
