At United Soils, Inc. we use Agvance Mapping Software to produce maps for the customers.  Agvance is a precision software program developed by Software Solution Integrated.  This software along with our Lab software keep track of the soil samples from the time they are ordered until they are billed.  Each customer is given a 'base' map of their field showing boundary, sample points, total tillable acres, size of grid and county-twp-section coordinates. If requested by the customer, they will get colored maps, either gridded or contoured,  of the results of their testing.  Basic maps are of pH, P, K results. 

Examples of Gridded maps:
Basemap    pH map    P map   K map

Examples of Contoured maps:
