摘要：
A system 100 and a method 300 for processing soil. The system comprises a soil processing device 110, arranged to be moved on a soil surface； and a driving device 60, e.g. a vehicle, arranged to move the soil processing device 110 on a portion of the soil surface 170. The soil processing device 110 includes a frame 112, arranged to slide or roll on the portion of the soil surface 170 during operation of the system 0； and at least one substantially horizontal pipe 114, attached to the frame 112, extending along an underside of the frame 112, at a predetermined depth. The pipe 14 has a plurality of apertures 116 along its length, and is connectable to a vacuum generating device that provides an underpressure in the pipe. The system further comprises a protective cover 150 attached to an upper side of the frame 112, the portion of the soil surface 170 and the cover 120 defining a compartment. A conduit for a heated gaseous medium is connectable to a device 162 which provides a heated gaseous medium to an inside of the compartment. The system further comprises a first temperature sensor 220 arranged to measure a first temperature in 1 soil below the soil processing device 110, and a control device 210, configured to adjust a speed of the vehicle 160 in dependency of a signal provided by the first temperature sensor.
