- 5. ACCORDING TO USEPA: • Yard waste accounts for 18% of refuse dumped into landfills • Food SCRAPS are another 19%* • This rises as high as 50% during growing season • 25% tree leaves and limbs • 75% grass clippings • 1/3 of all municipal landfills expected to reach capacity soon; new sites are difficult and EXPENSIVE to establish * Wikipedia - http://en.wikipedia.org/wiki/Food_waste#Landfills_and_greenhouse_gases

MOnEy • HanoverCounty MGs started a county-wide composting program that extended the life of their land fill by 10+ years and kept waste management taxes down • Healthier plants from veggies to ornamentals. $ • One of The USA’s biggest exports is soil, and we’re Maybe Not getting the best return for it. • A yard of Halifax Topsoil = $35. ~70yards in an Acre = $2450. Can you make a compost tea to spray over an acre for less than $2450? (Yes!) • Composting is not just top down—It helps feed soil life and those organisms do the heavy lifting of making good soils. They can even do it from down below, converting subsoil to top soil. • Save by using what you’ve already got on hand. Compost is the best way I know of to make the right food available in the right form in the right place at the right time. Forget adding lime and sulphur and focus on feeding your soil life.
- 8. FAmIly • It’sYOU friendly—if you’re concerned about putting toxic chemicals in your yard or food garden, having compost on hand is AWESOME! • you can make compost tea to improve the health of your plants. • It’s cheap and natural and helps get the biology right in your soil. • If your focus or even a part of your yard and garden is about food for you or your loved ones, there is no fresher food nor potentially more nutritious than what you pick outside your door. No loss or damage during transportation, you know the chemicals used on it (hopefully none), Where the water comes from, and the labor.
- 9. ENvIrOnMeNt • Keeporganic matter out of the landfill; wastes tucked into a plastic bag are taken out of the carbon cycle essentially forever. • It takes 100s of years to make inches of topsoil. Composting makes soil. • The amazing alluvial soils built up over millennia are not the result of chemical dumps of lime, calcium, or phosphorous from an agrochemical company. They’re the result of the natural breakdown of plant and animal bodies and things get sorted out just perfectly. • It is not rocket science. Stuff WANTS to break down for gosh sake. Entropy is the order of the universe.

- 12. WHaT Is COmPoStIng • “Composting is pretty simple. It’s taking any kind of organic matter and stacking it up so that nature will take its course and between bacteria and fungi and insects it will break down.” • It’s an AEROBIC process (with oxygen) ~Jack Spirko • Air flow is important: without it, things break down anaerobically causing stink, rot, and taking a long time to break down
- 13. There’s only twothings you’ve got to know about –Felder Rushing composting: 1) Stop throwing that stuff away, 2) and Pile it up over here.

- 19. A FEw POiNtErs • More diverse is better • make sure there’s no herbicides, pesticides, fungicides, or other-cides in your materials, including alLelopathogens. • Do NOT use Dog or Cat Manure (if the compost is for food crops) • Do NOT waste time, money, or other resources on exotic ingredients like cocoa hulls or lama droppings or something trendy. Work with what you’ve got.
- 20. COmPoStInG BLaCk WAlNut? “The presence of juglone is highly concentrated immediately under the leaf canopy of black walnuts, both from the tree roots and the accumulation of dead and dying debris. Decaying roots from a dead black walnut tree can still contain juglone for many years. The leaves containing juglone may be composted where the juglone will break down in several weeks from the presence of bacteria, air and water. If you want to test the toxicity of composted walnut leaves, plant tomato seedlings in it. Tomatoes are highly sensitive to juglone and will quickly die in its presence.” Read more: http://davesgarden.com/guides/articles/view/1186/#ixzz3IX51y6pI”

- 25. COmPoStInG STePs 1.Pile up a mixture of yard wastes by alternating layers of mostly carbon materials (browns) with layers of mostly nitrogen materials (greens). Do this until you are out of materials. When it stops looking like the stuff you put in the pile and more like crumbly soil, it’s done. 2. End of steps.
- 26. COmPoStInG tIpS -LEvEl 1 1. keep the pile moist — rain, garden hose, rain barrel. But not sopping wet. 2. turn it every few days. Especially if smelly. 3. It goes faster with smaller pieces. Chip, chop, or shred.
- 27. COmPoStInG tIpS -LEvEl 2 1. Cover the pile with a tarp to keep moisture in AND out. 2. turn the pile to keep things aerobic and fluffy. you don’t want compaction or anaerobic conditions. 3. If you smell Ammonia, Vinegar, Sour Milk, Vomit— anything unpleasant your compost is going anaerobic too quickly and losing nutrients. And possibly being a nuisance. Turn the pile. 4. You may want to inoculate a new pile with good soil.
- 28. COmPoStInG tIpS -LEvEl 3 Annuals prefer bacteria-dominated soils Perennials prefer fungal-dominated soils 1. More acidic conditions for annuals = bacteria. feed their compost with molasses or Kelp. 2. Less acidic conditions for perennials = fungi. feed their compost with woody materials. You may Lean slightly one way or the other. know that 1. There will always be exceptions, But 2. Healthy soil sorts all that pH stuff out.

- 30. CArBoN To NItRoGeNRAtIos • Wide C:N ratio, 100 parts Carbon to 1 part Nitrogen - dried grass trimmings, leaves, straw—those are foods for growing fungi more than other things • Narrower C:N ratio, 30 parts C to 1 part N - food scraps, green grass—food mostly for bacteria • Very narrow C:N ratio, 10 parts C to 1 part N - fresh manure, legumes, meat—“party foods” for microbes to grow really fast and generate high temperatures ~Dr. Elaine Ingham, SoilFoodWeb

COmPoStInG WoRmS (REdWRiGgLeRs—EIsEnIa FOeTiDa) • Poop factories • Perfect for kitchen scraps—coffee, greens, veggies, fruits • avoid meats and oils • Citrus and onions tough to break down (purée!) • 90 Days to good castings • Be sure to add some grit • Earthworms don’t do well in containers— solitary creatures
- 43. EArThWoRms • Ifyou're concerned about toxins from previous pesticide and herbicide use, grow earthworms. In their digestive systems are the beneficial protozoa that will break down pesticide material. Psuedomonas—pesticide decomposers in earth worm guts. Bacillus species. Protozoa species. Earthworm castings (earthworm manure) is good stuff. Human pathogens at the front end of the earthworm are broken down after going through the earthworm. They do not survive passage through the earthworm digestive system. • Earthworms are predators, not decomposers.

Adults have no functioning mouths, extremely docile, don’t fly around much to land on your food. Actually prevent houseflies and blowflies from placing their eggs in the same space. • Voracious eaters, Breaking down high-nutrient waste well, whereas earthworms better at breaking down high-cellulose materials. • Excellent fodder for poultry, fish, pigs, turtles, even dogs. Nutri-packets! 40-30-30. • They will self-harvest! • NOT a worm competitor, though things can get wet. If so, Add dry bedding. http://forums.gardenweb.com/forums/load/verm/msg0401113220154.html

- 53. BEnEfItS AnD SUch • It’s pretty much just buried wood. • Grow a typical garden with less irrigation and/or NO fertilization. • Use up rotting wood, twigs, branches and even whole trees that would otherwise go to the dump or be burned. • Fill with dirt, kitchen scraps, manure, leaf litter, et al. Water well. • Can be flush with the ground, although raised garden beds are more typical. • Can start small, and be added to later; can always be small - although bigger is better. • The wood doesn't have to be old to be used. Fresh is fine. • No chipper/shredder and no tilling. • Get’s easier every year, and does benefit from “curing” before planting. • NOT for trees (That’s swales) because settling will occur.
