A storage clamp is a compact heap, mound or pile of materials [1] used in the agricultural industry for temporary storage of root crops such as potato, turnip, rutabaga, mangelwurzel, and sugar beet.
A clamp is formed by excavating a shallow rectangular depression in a field to make a base, with the earth scraped from the field reserved to use as cover. Root crops are then stacked to a height of about 2 m (6 ft 7 in) then covered to a depth of several inches. Straw or old hay may be used to protect the upper surface from rain erosion.
A well-made clamp will keep the vegetables cool and dry for many[ vague ] months. Most clamps are relatively long and narrow, allowing the crops to be progressively removed from one end without disturbing the remaining vegetables. The use of a clamp allows a farmer to feed vegetables into market over many months.
