PROBLEM TO BE SOLVED: To enable correct determination as to which field of plural fields the farm work information of a farm work performed in the plural fields corresponds to.SOLUTION: A management device includes: an information storage part 30 for storing farm work information of a farm work performed by an agricultural machine 2 in plural fields, the information correlated with a work position of the agricultural machine 2 detected by a GPS system; a map data storage part 31 for storing map data of each field; and an information sorting part 32 for sorting out, for each field, the farm work information stored in the information storage part 30 by using the work position and the map data. Further, the information sorting part 32 includes: a shift amount calculation part 40 for calculating a shift amount between the work position detected by the GPS system and a position determined for a field; and an information correlation determination part 32 for determining which field indicated by the map data the farm work information stored in the information storage part 30 corresponds to, on the basis of the shift amount calculated by the shift amount calculation part 40. |
