| 摘要 | An auger useable for creating an opening in the ground for a soil sensor housing wherein the sensor housing has a predetermined volume and a tapered outer surface, includes an auger made in accordance with the methods described and defined in this specification. The auger having a shaft having an outer surface of circular cross-section having an larger outer diameter at one end than the other end and a strip material having a helical shape with an inner wall having a larger inner diameter at one end than the other end of the helical shape wherein the helically shaped material is fixed over the outer diameter of the shaft to form a tapered auger with helical flighting. The volume of the opening created by an auger in the ground will provide a matching volume for a sensor housing of a predetermined volume such that substantially the full length of the tapered outer surface of the sensor is adjacent the ground along the full length/depth of the created opening. | ||||||
