摘要
To provide a soil characteristics survey device capable of efficiently acquiring high precision data information about the distribution of soil characteristics in an agricultural field, and managing the data information collectively.;The soil characteristics survey device is composed of a pedestal connected to the rear of the tractor, a control unit (a computer) mounted on the pedestal, and a soil excavating unit attached below the rear end of the pedestal. While being towed by a vehicle 2 such as a tractor, the device surveys in real time the distribution of soil characteristics in a given agricultural field. At the top of the control unit is attached a GPS antenna. The soil excavating unit 50 is composed of a shank 51 connected to the bottom of the pedestal and a sensing unit which is fixed so the bottom of the shank 51 and advance in the soil approximately parallel to the ground at a predetermined depth. The control unit 30 generates data information groups corresponding to the same soil samples, concerning soil characteristics to be detected or the detection signals of differently arranged sensors 57, 53, 61, 62, 63, 64, and the like.
