Among the techniques for soil moisture evaluation, the use of Time Domain Reflectometry (TDR) stands out, which consists of an indirect, non-destructive, fast and accurate method less dependent on environmental factors. However, works carried out after its applications suggest the influence of factors related to soils structural and mineralogical characteristics, which makes necessary the site calibration for the TDR proper functioning. The aim of this work was to study the influence of bulk density (Ds) on the volumetric soil water […]

The technique of TDR (time-domain reflectometry) is an important tool for the study of soil water content. For a correct use of this technique, models that relate the volumetric water content in soil with the soil dielectric constant must be calibrated, considering the characteristics of each soil. The purpose of this study was to evaluate the influence of soil type and sampling form (disturbed and undisturbed samples) on the dielectric constant (Ka) of the soil and the performance of models […]
