Composting the University of California way

Compost  Decomposed organic matter that can be used as a soil amendment (improves                       texture and adds beneficial micro-organisms)

Mulch      wood chips, bark, straw, stones and other materials put on top of soil to                                             suppress weed growth, maintain soil moisture and keep soil cooler in summer  and                           warmer in the  winter.  Organic mulch will slowly release nutrients as it decomposes.

 

To make compost:

Need 50-50 mix of greens and browns plus oxygen and water.

  • Greens (nitrogen) – still-green leaves, horse, cow or chicken manure, fruit scraps, coffee grounds, grass clippings, tea bags

  • Browns (carbons) – dried leaves, un-coated paper, some fireplaces ashes

 

Ideal Volume  one cubic yard in three-bin system – incoming, working and finished.  “Working” bin should be on earth (not hardscape). Easy to move when turning

  tumblers, stacks, electric composters

 

No: animal waste from meat-eaters, pine needles and palm leaves (too acidic and very slow to break down), processed wood, weeds, meat, cooked foods, enzymes or other additives, glossy or colored paper, diseased plants, oil, grease or fat

 

Layer and then moisten the green-brown mixture. Interior temp should read 160 degrees within 3 days.  Then “turn” the pile; that is, remix it. Do this for up to 8 weeks.

Balanced compost pile = no smell, flies, roaches, mice, rats or other unwanted

Normal release is carbon dioxide and water vapor only.

 

Problems and Fixes:

  • Ammonia/sulfur odor means fermentation taking place – mixture is packed to densely (not getting enough oxygen).

  • Musky smell – mixture is too wet; spread out to dry

  • Low Internal Temperatures – low green content; add more greens

 

Vermicomposting (worms) – Shaded, covered location; use red wigglers, moistened newsprint and leaves
