TRANSCRIPT

  • Worm Composting

  • VermicompostingWHAT Process of using worms to recycle organic material and food scraps into worm compost, or vermicompost (vermiculture)

  • VermicompostingWHY Advantages Easy to do year-round SEVEN times richer in nutrients than regular compost No turning, no odor, & little watering worms do the work Benefits Environmental Economic Soil health Plant growth and vigor Fun and educational

  • VermicompostingWHERE Almost anywhere Indoors, Outdoors Dark, Warm, Moist, Ventilated

  • VermicompostingHOW Aerated container Bedding such asshredded newspaper Moisture and propertemperature Small amount of soil Redworms & food waste

  • Vermicomposting in ActionAerated Container Worm Bin

  • Vermicomposting in ActionBedding

  • Vermicomposting in ActionMoisture & Temperature

  • Vermicomposting in ActionStarter Soil & Redworms

  • Vermicomposting in ActionRedworms (Eisenia foetidaie & Lumbricus rubellus) Live in the top 12 inches of soil Feed on organic decaying matter Can eat their body weight in food every day Generate 75% of body weight in worm poop (castings) each day Lay one cocoon every week or so Each cocoon produces 3 to 4 baby worms Begin breeding at 4 to 6 weeks of age Worms can double population every 90 days Live up to 2 years

  • Vermicomposting in ActionFood WasteYES Most fruits and veggies Coffee grounds and filters Tea leaves and bags Egg shells Most cereals and grains (oatmeal, pasta, rice, cornmeal, pancakes, breads)MAYBE Onions Garlic Ginger

  • Vermicomposting in ActionFood WasteNO Meat, fish, dairy, oil, or bones Potato chips, candy, oils CitrusNO-NO's Plastic Rubber bands Sponges Aluminum foil Glass

  • Vermicomposting in ActionHarvesting Vermicompost

  • Vermicomposting in ActionHow to Use Vermicompost Excellent fertilizer; will not burn plants Use as mulch or soil conditioner in homegarden Use in potting soil mixes for houseplants Use as top dressing for lawns Combine with potting soil mixes and useas medium for starting young seedlings

  • Vermicomposting in ActionCompost Tea Liquid produced from vermicomposting Protects plants from disease Improves nutrient retention Decomposes harmful chemicals Transforms compacted soil into healthy soil Reduces water usage Decreases run-off and leaching

  • Composting vs. LandfillingSome Numbers to Consider Food and yard waste account for at least 25% of landfill materials AA dining halls generate 700 pounds food waste each week 12% of total greenhouse gas emissions generated from growing, preparing, and shipping food Eating 1 pound of food daily generates 1.5 tons of carbon dioxide (CO2) annually CO2 impact from edible food waste per person equates to taking 1 to 4 cars off the road CO2, methane(CH4), and nitrous oxide (N2O) generated as organic waste decays in landfills CH421 times worse and N2O 300 times worse than CO2 Proper composting minimizes greenhouse gas emissions and extends life of landfills by saving space

  • Q & A Prize PatrolTRUE or FALSE Redworms consume almost all types of waste, including bones, glass, and plastic

  • Q & A Prize PatrolTRUE or FALSE If you cant find redworms, use earthworms in your worm bin

  • Q & A Prize PatrolTRUE or FALSE Besides being beneficial to plants and the soil, compost tea can be applied to the scalp to reverse male pattern baldness

  • Q & A Prize PatrolTRUE or FALSE On average, weekly food waste from the AA dining halls exceeds 350 pounds

  • Q & A Prize PatrolWorm bins should be constructed so that the sides of the container are: Less than 3 inches high Exactly 5 inches high Between 8 and 12 inches high More than 12 inches high

  • Q & A Prize PatrolYou need about ?? square feet of floor space in your bin for every 1 pound of food waste 6 Square Feet Exactly 1.562 Square Feet 1 Square Foot Since when are square?
