Composting, natural farming workshop

THE Guam Environmental Education Committee for Earth Day 2012 recently organized a workshop on “Natural Farming and Easy Composting” at the University of Guam Triton Farm in Chalan Estudia, Dededo.

John Lawrence, assistant director of the National Resources and Conservation Service, made an interactive presentation on the essential steps for composting by demonstrating methods that can be easily done at home.

According to Lawrence, “composting is for everyone” and it “involves separating and managing waste streams into compostable and non-compostable materials, into wet and dry stuff.”

Compostable materials include kitchen wastes, coffee grounds, egg shells, vegetable scraps, and fruit skins. Leaves, grass clippings, and shredded wood can also be used as compost.

During the presentation, Lawrence stressed that residential food waste should not be used as compost for small-scale gardens.

Lawrence demonstrated alternating layers of brown materials like dried leaves, green materials, and a nitrogen source such as poultry manure or fertilizer. An essential compost pile requires moisture, oxygen, carbon and nitrogen to properly decompose.


Lawrence said composting is very viable for a single person, for a couple, or even a large family. From composting, a household can save at least $35 a month, the same amount paid for monthly trash-hauling service.

The “Natural Farming and Easy Composting Workshop” is just one of the activities organized by the Guam Environmental Protection Agency and other members of the Environmental Education Committee for Earth Month 2012. Other activities are posted in Guam EPA’s website.
