Soil and vegetation temperature
The temperature of the soil and vegetation will be measured during the collection of hand-held soil moisture sensor readings. For each field, four sampling locations will be selected to measure soil temperature at two depths –5 cm and 10 cm– using a digital thermometer.
At these same sampling locations, soil and vegetation surface temperatures will be recorded using a thermal infrared thermometer for sunlit vegetation and sunlit soil, as well as for shaded vegetation and shaded soil.
|Sampling location||Depth||Instrument||Measurement technique|
|Soil temperature||4 sites:1, 8, 9, 16||5 and 10 cm||Digital pocket thermometer||Insert to 5 cm, take reading, then push to 10 cm, take reading.|
|Soil and vegetation temperature||4 sites:1, 8, 9 16||Surface||Thermal infrared thermometer||Measure sunlit and shaded soils, sunlit and shaded vegetation.|
