Technical Abstract: Soil heat flux is an important component in studies of the soil thermal regime and the energy balance at the land surface. A number of methods for measuring soil heat flux have been proposed and utilized, but relatively few direct comparisons of the methods have been conducted under field conditions. As a result, the errors associated with soil heat flux measurements under field conditions are not clearly defined. Additionally, recent developments in heat pulse sensors have given rise to new possibilities for improving soil heat flux measurements. Measurements of soil heat flux were conducted under a bare soil surface, a soybean [Glycine max (L.) Merr.] canopy, and a corn (Zea mays L.) canopy. This poster will compare several traditional methods for determining soil heat flux as well as new methods utilizing heat pulse sensors.
