Abstract
A soil sampling implement and method have a sampler assembly supported from an implement frame for movement across a field. The sampler assembly includes a tapered cylindrical cutting shoe and a soil collection trough. The cutting shoe has a leading cutting edge arranged for movement through soil in a horizontal direction to cut a cylindrical core sample. A sensing device is provided for measuring at least one soil property. The sampler assembly is moved between a lowered position in which the cutting shoe is positioned at a selected sampling depth, and a raised position in which the cutting shoe is positioned above the soil surface and a soil sample contained in the soil collection trough is brought into contact with the sensing device. A cutting shoe scraper engages and cleans the leading cutting edge of the cutting shoe when the sampler assembly is moved between the lowered and raised positions.
