摘 要：正 Georeferenced measurements of soil strength can provide information useful for site-specific management. Because the conventional instrument for obtaining such measurements （i.e., cone penetrometer） provides only point data, we developed a horizontally operating on-the-go soil strength profile sensor （SSPS） that provides measurements at five depths up to 50 cm.
