The effects of dense plant roots on the time-domain reflectometry (TDR)-measured composite dielectric constant, epsilon(c), and soil-water content, theta(TDR), were investigated by laboratory experiments with root-mixed sand and loam soil. TDR ove...

Time Domain Reflectometry (TDR) measurements revealed the abrupt change in the slope of the relationships between dielectric constant (DC) and water content (theta) for soils and sand-kaolin mixtures of heavy texture. The calibration curve DC(thet...

Recently, it is noticed that the measurement method of soil water content from the dielectric constant of soil, and TDR (time domain reflectometry) method and FDR (frequency domain reflectometry) method are frequently utilized. However, these meth...

Kellner Erik; Lundin Lars Christer, 2001: Calibration of time domain reflectometry for water content in peat soil. Since peat soil differs from mineral soil in several respects, mineral-soil calibration functions for time domain reflectometry (TDR) are not necessarily applicable. This paper evaluates a number of calibration functions, both empirical polynomial...

The amount of liquid water (theta-L) present in soils at sub-freezing temperatures affects soil infiltrability, soil solution migration, and soil-atmosphere energy exchange. For these reasons, a number of frozen soil simulation models calculate th...
