SOIL SURVEY DEVICE AND SYSTEM FOR PRECISION AGRICULTURE

摘要

An optical soil survey device (40) to survey the optical characteristics of a given underground soil, a soil survey device to survey the soil, a soil survey system and a mobile soil survey vehicle to survey the soil are disclosed. The disclosed devices and systems may be used to survey the characteristics of a given soil for agricultural purposes. This survey can be carried out without experiencing significant resistance from the soil. A plow-shaped optical soil survey device (40) may be provided with a plow-shaped main unit, whose forward extremity turns up soil; a frame (42), which supports the sensor and connects a tractor and a main unit; a spectrometer (43), which is mounted on the frame (42); a wheel, which surveys the depth of the furrow and is connected to the main unit (41) via an arm; and a survey control unit, which is mounted on the tractor.
