Description:Excerpt from An Evaluation of Dial Thermometers for Measuring Soil Temperature The dial type thermometers were installed by forcing the stem into the ground to the desired depth. Soil temperatures were read directly in degrees Fahrenheit from the dial scale without disturb ing the thermometers. A point 1 inch from the bottom of the stem was taken as the reference for depth. The 8 inch thermometer was therefore sunken into the surface by'l inch. The thermistors were installed by removing a small core of soil to the desired depth and placing the thermistor pellet, with the lead wires attached, on the bottom of the hole. The soil was replaced and firmed around the pellets and lead wires. The lead wires were brought out and fastened to a platform on top of a post 3 feet tall to facilitate reading the ohmmeter used to measure the resistance of the thermistor. Soil temperatures were determined from a calibration curve previously' About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
