  1. DECOMPOSITION and Aerobic Thermal Composting By: Molly Haviland for Living Soil MUM 2013 Tuesday, April 2, 2013

  2. A BALANCED SYSTEM SUPPORTS 1. Soil Stabilization 2. Soil Aeration 3. Nutrient Retention 4. Nutrient Cycling 5. Water Retention 6. Plant Fertility 7. Carbon Sequestration Tuesday, April 2, 2013

  3. WHAT IS COMPOSTING? Tuesday, April 2, 2013

  4. WHAT IS COMPOSTING? “Composting is oxidative decomposition of a mix of different kinds of organic matter.” - Dr. Ingham Tuesday, April 2, 2013

  5. OXIDATIVE Tuesday, April 2, 2013

  6. OXIDATIVE “taking place in the presence of oxygen” AEROBIC “living with air” Anaerobic “living without air” Tuesday, April 2, 2013

  7. TOXINS RELEASED Under Anaerobic Conditions • Hydrogen Sulfide: H2S • Ammonia: NH3 • Phosphine: PH3 • Alcohol • Phenols Tuesday, April 2, 2013

  8. MONITORING O2 LEVELS • O2 Sensor • What Do You Smell? • Vinegar = Acetic Acid • Sour Milk = Butyric Acid • Vomit = Valeric Acid • Decaying Flesh = Putrescine Tuesday, April 2, 2013

  14. WHAT IS ORGANIC MATTER? • Anything that was once living Tuesday, April 2, 2013

  15. WHAT IS ORGANIC MATTER? • Anything that was once living • C-C linkages Tuesday, April 2, 2013

  16. AEROBIC THERMAL COMPOSTING • Kills Pathogens and weed seeds • Finished in 2-4 Months • Stable Inoculum • Labor Intensive Tuesday, April 2, 2013

  17. POINTS TO CONSIDER • Location • Size • Temperature • Moisture • Ingredient Ratios Tuesday, April 2, 2013

  18. TEMPERATURE Organic Standards Require • At or above 131 F for 10-15 days • Turned 5 times within those days Tuesday, April 2, 2013

  19. MOISTURE • Soil Moisture Meters • Hand Squeeze Method • Water Quality Tuesday, April 2, 2013
