The development of GPS and GNSS has made precision farming possible. The ability of the farmer and/or researcher to pinpoint their exact location within a field enables the creation of maps of the spatial variability of as many variables as can be measured (for example, crop yield, terrain features/topography, organic matter content, moisture levels, nitrogen levels, pH, EC, Mg, K, and others).
