The soil temperature sensor should be buried in the soil. How deep it should be buried depends on the
goal you want to achieve with the sensor. To have an impression of root growth and nitrogen
mineralization in vines or apples in early spring it is best to bury it between 10 to 20 cm. If you want to
assess the emergence possibilities of seeds it depends on the seeding depth of the seed. Using it in corn
(maize) would mean to bury it at 5 cm and using it for sugar beets would mean to bury it at 2 or 3 cm only.
