Abstract
An automatic soil sampler (10) removes soil samples (65) at known locations and transfers the samples to a packaging station (23) where the samples are packaged and identified. The packages (87) are left in a strip and moved to an analysis workstation (219) for analysis of soil. The results of analysis of each soil sample (65) is used for determining applications of a materials such as fertilizer in that same local region as the region where the soil sample was taken with an applicator (11B) moving over the same field.
