Hilhorst 2000

WebRecent work by Hilhorst (2000), has taken advantage of the linear relationship between the soil bulk dielectric permittivity (εb) and σp to allow accurate conversion from σb to σp if the εb is known. The 5TE measures εb and σb nearly simultaneously in the same soil volume. It is there-fore well suited to this method. Webusing the Hilhorst equation (Hilhorst 2000 ).
