9. The work map provision server according to claim 1 , wherein the second processor-executable code causes the work vehicle to apply a first target amount of fertilizer to a first area of the farm field and a second target amount of fertilizer, that is different than the first target amount, to a second area of the farm field.
10. A work map provision server comprising:
a memory configured to store first processor-executable code, a plurality of fertilizer application maps, and respective attribute information for each fertilizer application map of the plurality of fertilizer application maps, wherein:
the respective attribute information for each of the fertilizer application maps includes scheduled work period information indicating a period of time during which a corresponding fertilizer application map is to be used and work identification information indicating work for which the corresponding fertilizer application map is to be used, and
each fertilizer application map of the plurality of fertilizer maps is composed of second processor-executable code that, when executed by a processor of a work vehicle, controls the work vehicle to apply a target amount of fertilizer to each respective area of a plurality of areas in a farm field; and
a processor in communication with the memory, the processor configured to execute the first processor-executable code to:
receive a map acquisition request at a receiving time and date, the map acquisition request including map narrowing-down information that includes information specifying work to be performed,
select, from among the plurality of fertilizer application maps, a fertilizer application map based on scheduled work period information of the fertilizer application map indicating a period of time that includes the receiving time and date of the map acquisition request, and on the work identification information of the fertilizer application map indicating work that includes the work to be performed of the map acquisition request, and
transmit the fertilizer application map for use by the work vehicle.
11. The work map provision server according to claim 10 , wherein the second processor-executable code causes the work vehicle to apply a first target amount of fertilizer to a first area of the farm field and a second target amount of fertilizer, that is different than the first target amount, to a second area of the farm field.
12. A work map provision server comprising:
a memory configured to store first processor-executable code, a plurality of fertilizer application maps, and respective attribute information for each fertilizer application map of the plurality of fertilizer application maps, wherein:
the respective attribute information for each of the fertilizer application maps includes farm field location information indicating a location of the farm field for which a corresponding fertilizer application map is to be used, work identification information indicating work for which the corresponding fertilizer application map is to be used, and scheduled work period information indicating a period of time during which the corresponding fertilizer application map is to be used, and
