Abstract: A fertilization map creating system includes a growth sensor, a GPS device, and a growth information accumulating part that stores data, a fertilization map being created based on growth data and position data stored in the growth information accumulating part, and the growth information accumulating part storing the position data and the growth data while a tractor drives in a field. The system further includes a growth condition calculation part that obtains a growth condition of previously set each area in the field based on the data stored in the memory; a fertilization amount calculation part that obtains an amount of fertilization of each area based on the growth condition of each area; and a map creating part that creates the fertilization map showing the amount of fertilization of each area obtained by the fertilization calculation part.
