Abstract
Abstract The present invention is drawn to a system of treating a field of interest. A plurality of soil samples are taken from different geographic locations in the field of interest. Geographic identifiers are determined for each of the plurality of samples wherein the identifiers identify the geographic location from which the sample was taken. The samples are analyzed to determine a plurality of soil characteristics indicative of soil condition. A plurality of data bases are accessed to obtain field characteristics corresponding to the field of interest, the field characteristics being indicative of current and historical information corresponding to the field of interest. A program for applying material to the field of interest is determined based on the soil characteristics, the geographic identifiers, and the field characteristics. The program is loaded into a controller operably coupled to an applicator. The applicator is controlled according to the program to apply material to the field of interest.
