In order in to keep our compost piles productive we add oxygen by turning and water by hosing it down to keep the piles as wet as a wrung-out sponge. While turning we can observe what decomposers are present: red worms, sow bugs, roly poly bugs (both are actually crustaceans) ants, centipedes, millipedes. We also look for signs of beneficial bacteria & fungus which are microscopic, but they do leave evidence of white skeletal patches. All these creatures eat or absorb the organic matter we have added to the piles (leaves, branches, garden waste) and turn it into fabulous compost. Why is compost good for the garden? We process a lot of garden waste with this system so it doesnt have to be hauled off to the landfill, compost is organic matter and holds water in the soil, and it adds humus, a kind of glue that holds soil particles together. It also adds beneficial fungus and beneficial bacteria that break down the soil releasing nutrients that are needed by plants and protect the roots of plants from non-benificials. We have sped up the video to illustrate the pattern of turning and watering the piles . The result is three piles: one we add "greens & browns" to on a daily basis, a second pile that is composting (we only need to turn and water it once in awhile) and a third pile that we are currently harvesting through a screening system.
