SOLUTION: A precise agricultural method is, for example, performed by controlling the amount of fertilizer application, etc., by soil analysis through the use of a sample tray 1 in which a large number of sampling pots 2 are vertically and transversely formed. The sampling location of soil to each pot 2 of the tray 1 is detected, for example, by the GPS and is stored in a magnetic disk 14, etc. The tray 1 containing samples inside is supplied, for example, for a soil analyzer 9 and is moved from a supplying table 10 to a discharging table 11, and a soil sample in a predetermined pot 2 recognized by a sampling pot reading device 12 is automatically analyzed by a soil analysis controller 13. From the analysis data corresponding to each pot 2 and the sampling location data of the disk 14, a soil map indicating the soil analysis data and corresponding to the shape of a field is created.COPYRIGHT: (C)1999,JPO
