| | Compost windrow turner - Wikipedia, the free encyclopedia |
| | With a self-trailering option this allows the compost windrow turner to convert itself into a trailer to be pulled by a semi-truck tractor. | | | Although smaller machines exist for smaller windrows, most operations need the larger machines to be efficient. | | | These two options combined allow the compost windrow turner to be easily hauled anywhere and to turn the compost in muddy and wet locations. |

| | Regardless of the method, composting requires about a $12,600 equipment investment for using a tractor (calculated by assuming 40 percent of its use is loading and hauling) and for buying a solid manure spreader, based on a 60-cow farm. | | | Their research suggests composting can spare farmers from expensive long-term storage systems that require high structure and upkeep costs, especially if farmers are willing to share compost equipment or use existing farm machinery. | | | Composting using a turner and tractor requires another $16,600 equipment investment, for a total of $29,200. |

| | While the nutrient content of yard waste compost is too low for it to be considered a fertilizer, it is a valuable soil conditioner and organic amendment which improves the physical, chemical and biological properties of the soil. | | | Composting -- The objective of yard waste composting as a solid waste treatment process is to reduce the mass and volume of the waste materials, diverting them from landfills, while converting the yard waste into a useful finished product for horticultural or agricultural use. | | | As composting progresses, new types of microbes, insects, and earthworms, among others, migrate to the windrow and continue the decomposition process. |

| | Increasingly, composting is used as a method to produce soil conditioners and amendments for agricultural applications. | | | Windrows are periodically turned using a windrow turner whose dimensions dictate the height and width of the windrow, while compost piles are generally turned using a front-end loader. | | | Staged grass addition is used at some composting facilities to reduce the percentage of fresh grass in compost mixes in an attempt to reduce odors during composting. |

| | Composting Horse Manure in Dynamic Windrows |
| | Compost is more valuable than raw manure/bedding for land application because the process: a) creates a more stable form of nitrogen for sustained release in the soil; b) lowers the ratio of carbon to nitrogen, preventing nitrogen deficiencies in crops; and c) has the potential to kill parasites and weed seeds. | | | Windrows of compost resemble these long rows of hay but are mounds of material instead of a flat layer of hay. | | | The term windrow was originally used to describe cut hay left in long rows to dry in fields. |

| | The finished pile was essentially a sandwich of the fish-compost material between the 0.61-m composting mixture base and the 0.61-m composting mixture cap. | | | To form the windrow, fish were offloaded onto a 0.61-m bed of the composting material, and then more material was added and mixed using a rubber tire loader with a 3-cubic-yard bucket. | | | The compost site is located on the Vinemont Farm, about 2 km from the USGS Leetown Science Center; the farm property borders the east-southeast boundary of the science center property. |

| | Composting |
| | Windrow composting is an established technology for dealing with green wastes in the UK, where the material is piled in elongated rows and aerated through either turning of the windrows or through air forced through the material. | | | For composting to occur in an optimum manner, five key factors need to be controlled; temperature, moisture, oxygen, material porosity and Carbon: Nitrogen ratio. | | | Typical materials suitable for composting include, green waste and putrescible wastes with pre-sorting and screening to remove non-compostables, plus other enriched organic waste streams (sewage sludge, agricultural, food processing wastes). |

| | Aerated Windrow Composting Composting US EPA |
| | In a warm, arid climate, windrows are sometimes covered or placed under a shelter to prevent water from evaporating. | | | Organic waste is formed into rows of long piles called "windrows" and aerated by turning the pile periodically by either manual or mechanical means. | | | The ideal pile height, which is between 4 and 8 feet, allows for a pile large enough to generate sufficient heat and maintain temperatures, yet small enough to allow oxygen to flow to the windrow's core. |

| | Municipal Windrow Composting in Laem Chabang, Thailand |
| | While the biological activity in a compost pile can be maintained at moisture levels as low as 15% and as high as 80% by weight, the optimum range is between 40 and 50%. | | | In temperate region composting operations, the moisture contained in food waste acts as a considerable supplement to what is required by the composting process. | | | Subjective analysis of six-week old compost in late December 1997 showed declines in temperature to near-ambient, no evidence of ammonia odour, no evidence of insects or larvae, no obnoxious odours, and clear evidence of whitish-gray patches of actinomycetes on and within the windrow. |

| | Manures for Organic Crop Production |
| | The possibility of transmitting human diseases discourages the use of fresh manures (and even some composts) as preplant or sidedress fertilizers on vegetable crops—especially crops that are commonly eaten raw (2). | | | Whenever you import large amounts of either composted or raw manure onto the farm, it is wise to inquire about the feeding practices at the source or have the material tested. | | | When the nutrients in raw or composted manure are eroded or leached from farm fields or holding areas, they present a potential pollution problem, in addition to being a resource lost to the farmer. |

| | Proper siting of the windrow is necessary to facilitate composting and preventing nutrient runoff into surface waters. | | | If the compost fails to heat up or is malodorous, the material is probably too wet. | | | You may need to add more water to the compost at this time to maintain the 40-60 percent moisture content. |

| | Windrow composting can be used to process yard waste, food, paper, and sewage sludge. | | | The compostable materials must be screened or hand picked for non-biodegradable materials, and then chipped, ground, or shredded into uniform particles that will decompose quickly. | | | Curing compost stabilizes it to prevent odors or other nuisances from developing while the material is stored. |
