But whether the specified operations will be done on the farm, as part of the farm work or away from it, and in either small neighborhood establishments or in larger industrial plants, will depend upon a variety of factors as great as that which comprehends the whole vast process of starting the nation’s crops, over 300,7 on their respective marketing courses. The initial steps in marketing such widely different products as cotton and apples; tobacco and milk; potatoes and citrus fruits; legume crops, wheat, corn and other grains, on the one hand, and tomatoes, strawberries, truck garden products, etc., on the other, are within the delegation.
The mere enumeration of these instances indicates some of the variables involved. Others add to the difficulty. Highly perishable crops, as fruits and vegetables, require immediate action in these stages of handling. Cotton, grains, root crops, etc., less perishable, may wait longer on the farm, some for months, before these processes become necessary. Some crops are highly concentrated for production in a few regions, such as citrus fruits in Florida, Southern Texas, and Southern California, but are marketed on a nation-wide scale. Others have regional areas of production, like cotton in the South, celery in Michigan, tobacco in the border states and a few northern regions, yet depend on the national market. Still others have regions of greater or less concentration, but are grown all over the nation, like wheat and other grains, apples, potatoes, etc.
Obviously, “area of production,” in the sense of where the commodity is produced for purposes of commercial marketing, will vary from the whole nation, in the case of the more common grains, fruit crops and root crops, down to a few highly concentrated regions or areas in
