Abstract: The present invention aims to provide a system that automatically shows multiple fertilization design patterns suitable for the soil and crop, in linkage with map data and in accordance with fertilization design conditions each including a different fertilizer pattern and priority condition so as to allow the user to compare the multiple fertilization patterns on the same screen. The system includes units configured to receive designation of an agricultural field on the map, then to receive a fertilization design condition including a fertilizer pattern and a priority condition, to design fertilization patterns for the agricultural field, and to display the designed fertilization patterns on the same screen.

Abstract: A device is provided that predicts in advance a farm that will be liquidated due to farm retirement or finds a renter of the farm. CPU 50 acquires determination timing. This determination timing may be acquired from one stored in advance or may be acquired externally. CPU 50 calculates age of each farmer at the acquired determination timing based on age information that is included in basic information. CPU 50 determines whether or not the age of the each farmer at the determination timing is a specified age or higher. CPU 50 predicts whether or not the each block will be a liquidated farm based on a determination result of the age determination means, information on presence or absence of a successor, and information on presence or absence of intention to expand about the farmer of the each block. CPU 50 outputs the block that is predicted as the liquidated farm and the block that is not predicted as the liquidated farm by the liquidated farm prediction in a distinguishable manner from each other.

Abstract: A crop traceability system includes: a terminal which moves together with a machine to harvest or transport a crop; and a server which receives an information from the terminal. The terminal includes: a location information acquisition unit which acquires a location information of the terminal; and a transmitter which transmits the location information and a machine ID of the machine to the server. The server includes: a storage unit which stores a location information of a planimetric feature; a receiver which receives the location information and the machine ID which are transmitted by the terminal; and an ID information processor which links the machine ID with a planimetric feature ID of the planimetric feature when a location information of the planimetric feature stored in the storage unit coincides with the location information transmitted by the terminal.

Abstract: Positional information transmitted from a mobile unit mounted on an agricultural work vehicle is displayed overlapping with map data obtained from a map database. Display of the field data on the display screen is color-coded based on a result of comparison of a date of the positional information transmitted from the mobile unit with the field data obtained from the map database and a scheduled date for work stored in the field data. Thereby, an operational management system of an agricultural work vehicle capable of promptly and spatially confirming an operational situation of the agricultural work vehicle is provided.
