Editing Seasonal human migration (section)

==Seasonal agricultural migration==
While the culture of many crops (especially "dry" crops) has become entirely mechanized, others, such as fruits and vegetables, still require [[manual labour|manual labor]], at least for harvest, and some, such as tobacco, still need manual labor for its culture. Much of the work was once provided by family members or boarding students, but they are less available now, and farms are larger. Now, [[migrant worker]]s provide much of the hand labor required in agriculture in the US and other countries. Labor contractors arrange with [[farmer]]s to provide the necessary help at the seasonal time, often with foreign nationals whose employment opportunities are more limited in their home areas.

A number of migratory [[contract]]ors, known as "[[custom harvester]]s", move with their [[combine harvester|combine]]s to follow the [[wheat]] harvest in the [[United States]] and [[Canada]]. as the season moves north. Some [[crop duster]]s are also migratory, following seasonal patterns of need. In the large citrus districts of [[Florida]] and [[California]] seasonal pickers arrive for collection periods and often move with the changing harvest.

Most commercial [[beekeeper]]s in the US are migratory, spending [[winter]] in warm climates and moving with the spring to follow the bloom, or [[pollination]] [[contract]]s for [[almond]]s, [[apple]]s, [[blueberry|blueberries]] and other fruits and vegetables that require [[bee]]s. Migratory beekeeping also is practiced, especially in [[France]], [[Australia]], [[South Africa]] and [[Argentina]].
