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.

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


The Gutiérrez-Hubbell House Workshop Series Has Resumed

After missing a year due to Covid restrictions, we are now able to resume offering the quarterly composting workshop series at the beautiful and historic Gutiérrez-Hubbell House. For details and registration, please see GutiĆ©rrez-Hubbell House Backyard Composting Series.


Some Live Classes Have Resumed

Due to coronavirus restrictions we had to cancel many many classes over the past year and a half. We have gotten the go-ahead to start in-person classes again and some are now being offered. Please see the schedule and keep checking for new offerings. And, as always, 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.


You Can View Some of Our Classes Online

We have online presentations for three of our popular classes: Home Composting Basics, Composting with Worms, and Amending Desert Garden Soil. Classes are presented by BCE Master Composters. Please see our Class Schedule Page for a link and details.


Would you like to host an on-line composting presentation for your organization?

At your request, master composters will schedule and then teach on-line presentations for your group via Zoom or your preferred platform. Presentations will be from one to one and a half hours in length and will include group participation. Class topics and descriptions are at the bottom of our Classes and Activities for the Public page. In some instances, we may be able to tailor the presentation for your organization. Requests for a specific topic, along with date and time, may be sent to webmaster@nmcomposters.org. Please send your request at least 30 days prior to the proposed date. We will be in touch with you to satisfy your request and answer your questions.

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.
