includes the engineering properties plasticity index and liquid limit to further characterize silts and clays. There is no one-to-one correlation between the two systems. Efforts to link strength to percent sand, silt, clay, and bulk density as well as water content are mixed. Based on data from 16 locations collected by different researchers, Kumar et al. (2012) found almost no correlation between CI and the different soil properties if considered separately, but they did find fair comparison ( r 2

-band passive microwave satellite that measures brightness temperatures using an interferometric (multiangular) approach. Microwave emissions from the earth’s surface at L bands are attenuated by dielectric materials. These attenuation patterns can be used to estimate soil moisture due to the high contrast in dielectric properties between dry and wet soils. The estimation of soil moisture is complicated by other factors that impact the signal strength and attenuation, such as vegetation water content

in a central sector of the Duero basin; the climate is semiarid continental Mediterranean and the land use is predominantly agricultural with some patchy forest. This area is mainly flat, ranging from 700 to 900 m MSL. Each station was equipped with capacitance probes (HydraProbes, Stevens Water Monitoring Systems, Inc.) installed horizontally at a depth of 5 cm. Analyses of soil samples were carried out to verify the capacitances probes and to assess soil properties at each station ( Sánchez et
