13. Avaliação de uma sonda TDR helicoidal para a estimativa do teor de umidade de solos em campo e laboratório / Evaluation of a helicoidal TDR probe to estimate the soil water content in laboratory and in situ
In this work is presented the evaluation of a recently developed helicoidal probe used for estimating the soil water content through the time domain technology (TDR). This probe has been calibrated in laboratory for different types of soils. The calibration process consisted in assessing the values of the apparent dielectric constant (Ka) and the bulk electr
