Become a Master Composter!

  • Minimize your carbon footprint. Keeping food and yard waste out of the landfill reduces harmful methane gas emissions.
  • Use this “waste” to create amendments for your garden. Compost use reduces the need for synthetic fertilizers and pesticides. 
  • Reduce water use and increase water retention. Compost increases your soil’s water-holding capacity and improves water retention. 

The Master Composter course provides training in the art and science of composting through lectures, demonstrations, and a field trip.

The Course Covers the Following Topics:

  • Traditional composting & vermicomposting
  • Compost bin building and troubleshooting (in teams!)
  • Microbiology of composting
