Windrow

A windrow is a row of cut (mown) hay or small grain crop. It is allowed to dry before being baled, combined, or rolled. For hay, the windrow is often formed by a hay rake, which rakes hay that has been cut by a mowing machine or by scythe into a row, or it may naturally form as the hay is mown. For small grain crops which are to be harvested, the windrow is formed by a swather which both cuts the crop and forms the windrow.

Windrows of straw, along with stubble.

By analogy, the term may also be applied to a row of any other material such as snow, earth or materials for collection.[1]

• Snow windrows are created by snow plows when clearing roads of snow; where this blocks driveways the windrow may require removal. Snow windrowed to the centre of the street can be removed by a snow blower and truck. In preparing a pond or lake for ice cutting, the snow on top of the ice, which slows freezing, may be scraped off and windrowed.[2]
  
• Earth windrows may be formed by graders when grading earthworks or dirt roads
  
• Leaf windrows may be required for municipal collection.
  
• Fossil windrows are a grouping of fossils that have been deposited together as a result of turbulence or wave action in a marine or freshwater environment. Fossils of similar shape and size are commonly found grouped or sorted together as a result of separation based on weight and shape.
  
• Seaweed windrows form on sea or lake surfaces because of cylindrical Langmuir circulation just under the surface caused by wind action.

Windrow composting is a large scale vermicomposting system where garden and other biodegradable waste is shredded, mixed and windrowed for composting.
