摘要：Soil thermal property data, especially as a function of water content, are currently not readily available.Demand for these data is, however, on the increase because of improvements in wider applications of soil heat andwater transport models, as well as, of the vegetal growth studies. Most of these investigations were focused in sandysoils, clayed soils or peat horticultural substrates, due to the different properties and applications of each ones.Otherwise, in order to partly fill the thermal soil properties studies into other types of soils, we focused this work in therelation between thermal and hydraulic soil properties of a silty soil under laboratory conditions. Samples wereobtained from Can Solé Road located in the Llobregat delta plain (NE of Spain), where frequently Cynara scolymus iscultivated. Small dual-needle sensors, employing the heat pulse methodology were used to measure the soil thermaldiffusivity, specific heat capacity and thermal conductivity. One soil column with a specific design was used. Thecolumn was monitorized to determine the volumetric water content and matric potential, as well as, the thermalproperties. To obtain these kinds of data a frequency domain probe and micro-tensiometer were used. Preliminarresults obtained up to now allow a rather complete understanding of the relation between thermal and hydraulicproperties at laboratory scale of the silty soils. Preliminary distributed water content and thermal data allowedinvestigating the variability of these properties and its relations between them for this type of soils.
