BACKYARD COMPOST FORMULA

 
 

COMPOSTABLE WASTE

  • Waste material can be either yard waste and/or certain household waste.
  • An ideal size for the pile is 3' x 3' x 3'.
  • Large pieces of waste material should be broken up by hand or shredded.
  • Check COMPOST INGREDIENTS list before adding waste materials.
 
 

 

OXYGEN

  • Turning the pile (moving the materials from the sides into the middle and from the bottom to the top) will allow oxygen to reach the organisms which break down the material.
 
 

 

MOISTURE

  • The pile should be moist, like a wrung-out sponge. Dry or wet piles will slow down the decomposition process.
  • Check compost moisture by squeezing a handful. A few drops should come out.
  • Adjust moisture by adding water to a dry pile or adding dry material to a wet pile.
 
 

 

TEMPERATURE

  • For optimum composting, the compost temperature should be 90° to 140°.
  • Consider checking the center of the pile periodically using a thermometer with a probe.
 
 

 

C:N RATIO

  • The pile needs a good balance of carbon and nitrogen materials to decompose properly.
  • The ideal C:N (carbon to nitrogen) ratio is 30:1 (30 parts carbon to 1 part nitrogen) or 30 parts leaves to 1 part grass clippings.
