ABSTRACT:
A ground soil moisture probe is constructed of a solid cylindrical rod with a solid soil-piercing bottom conical tip end an inverse conic section hard facing protuberance extending from above the rod tip end and fairing into the rod tip end. A tangential slot extends thereabove, forming with a flat stop of the protuberance a soil-collection and soil-holding shelf. The probe is inserted into the soil or sod being moisture tested to a predetermined depth, controlled by a depth-adjustable circular depth stop extending from the rod. The sample is obtained by a scraping action of the shelf outer edge on the sides of the hole made by insertion of the probe. A finger pinch test is described where a lop-sided sample ball of soil is pinched from the shelf and the general comparative amount of moisture in the sample determined by the feel and appearance of the soil sample to the operator.
