Soil temperatures are used to determine when conditions will be right for germination and growth of planted seeds, weed seeds, or insect growth. The measurement depth of these sites is 4 inches below the ground surface on a sod covered site. In spring and autumn the soil temperature can vary several degrees during the day, and the 24 hour summary data is the average for the day so the hourly data should be checked to evaluate the variation throughout the day. Four of the sites have measurements at 2,4,8,20,40, and 72 inches that are recorded at 0800 LST which provide further information on the condition of the soil profile at that site.

The source of the temperature data is South Dakota Automatic Weather Data Network (SD-AWDN) operated by:

South Dakota Agricultural Experiment Station
College of Agriculture and Biological Sciences
South Dakota State University

The SD-AWDN stations are interrogated daily by the Office of Climate and Weather Information, Ag & Biosystems Engineering Department
