Crucial factor for obtaining rich harvest is the quality of work on tillage. For example, compliance with the depth of sowing, as different crops, depending on biological characteristics, require different depths for seeds. Not the least role is played by the cultivation of the soil: its crumbling, loosening and partial mixing, as well as the complete destruction of weeds and leveling the surface. Spraying liquid nitrogen fertilizers is also important. According to the technology, nitrogen fertilizers should be applied to a depth of 15 to 20 cm. In case of deviation from the norm, the efficiency of tillage is lost.
That is why, for precise compliance with the standards of the work on tillage, trailing equipment is better to be equipped with a special ultrasonic proximity sensor, which will measure the distance from the platform of the sowing complex to the ground.
