Precision Farming addresses the small-scale variability of soil fertility parameters in the field and consequently transforms them into variable fertilizer applications. Geocoded information about spatially variable soil characteristics is required in a close enough distance of 30 to 50 meters to meet the spatial correlation which is a prerequisite for the interpolation of data in order to obtain Digital Agro Resource Maps (DARMs). The self surveying approach efficiently provides geocoded information of time constant soil parameters, such as geomorphology, and organic matter and clay contents in optional density. It combines Gobal Positioning System (GPS) navigation and positioning with human sensory capabilities.
