A windrow is a continuous row of plant (or mineral) residue spread out over a plot of land.
This term is most often used to designate rows of fodder, straw, crushed plants or cut branches formed during the use or maintenance of a plot of land.
Sometimes the term windrow also applies to continuous deposits of snow left by snowploughs.
Windrows may be temporary, before being collected, or left to stay in place until they naturally disappear.
