fields - choose a jigsaw puzzle to solve

In agriculture , a field is an area of land , enclosed or otherwise, used for agricultural purposes such as cultivating crops or as a paddock or other enclosure for livestock . A field may also be an area left to lie fallow or as arable land . Many farms have a field border , usually composed of a strip of shrubs and vegetation , used to provide food and cover necessary for the survival of wildlife . It has been found that these borders may lead to an increased variety of animals and plants in the area , but also in some cases a decreased yield of crops.
