WebJan 3, 2024 · Hilhorst (2000) has taken advantage of the linear relationship between the soil Richards, L.A. (Ed). 1954. Diagnosis and Improvement of Saline and Improvement of … WebThese data were then used to calculate pore water EC (using the Hilhorst (2000) approach). Our results showed that controlling substrate volumetric water content is easier than controlling the EC of the pore water in the substrate. However, the results also suggested that automated control of substrate water content and pore water EC is ...

WebNov 1, 2012 · Hilhorst (2000) presented a linear model connecting soil dielectric permittivity ε and σ b in the form (3) ε = A σ b + Β where Α = ε p /σ p ≅ 80/σ p, B = ε 0, the y-intercept of the line ε = f(σ b). ε p is the dielectric permittivity of the pore water and is considered equal to that of pure water (ε p = 80.3 at 20 °C (Hilhorst ... Weba capacitance sensor, values between 1.9 and 7.6 have been reported for ε0 (Hilhorst 2000). Calibration experiment Soil samples were obtained at the surface and at a depth of 0.6 m from the experimental field. The samples were washed by three pore volumes of distilled water. They were then air-dried, passed through a 2-mm hyperopt python package
