Abstract. There is need to understand the response of soil systems to predicted climate warming for modeling soil process response to climate warming. Current methods for soil warming include expensive and difficult to implement active and passive techniques. Here we test a simple, inexpensive in situ passive soil heating approach, based on easy to construct infrared mirrors that do not require automation or enclosures. The infrared mirrors consisted of 61 × 61 cm glass panels coated with infrared reflecting film. The mirrors as constructed are effective for soil heating in environments typified by open canopy and low canopy vegetation. Mirror tests were performed on several soils in a warm semiarid environment. Results indicated that the infrared mirrors yielded significant heating and drying of soil surface and shallow subsurface relative to un-warmed control treatments, and that warming and drying effects was soil specific with greater potential warming on soils with lower volumetric heat capacity. Atmospheric and soil moisture attenuated mirror induced soil warming. The results demonstrate proof-of-concept that the infrared mirrors may be used to passively heat the near soil surface, providing an inexpensive, low-maintenance alternative to other passive and active soil heating technologies.
