Abstract: An automated soil sampler is removably mounted on an agricultural tractor and collects soil samples in a farm field while the tractor is driven through the field. At a periodic interval, the soil sampler momentarily lowers a soil collection knife into the soil to collect a soil sample, raises the collection knife out of the soil, and transfers the collected soil sample into a bar-coded storage container. The GPS location of the soil sample is associated with the storage container's bar-code in a data file. The interval between successive periodic soil samples corresponds to a determined forward displacement of the tractor. Storage containers that have received soil samples are moved to a storage area until all of the soil samples for a given field have been collected.
