It is commonly believed that Time Domain Reflectometry (TDR) measures bulk soil electrical conductivity (EC) and volumetric water content within the same, well-defined sample volume. However, recent studies have shown that the sample volume is a func

Time Domain Reflectometry (TDR) is a recognized and widely used technique for measuring electrical conductivity (EC) and volumetric water content (θ) in porous media. The ability of TDR to measure both EC and θ is especially appealing in solute tra

Predictive models for the solute diffusion coefficient, D S , dependency on volumetric soil-water content, 0, are often applied in simulations of solute transport and fate in natural, undisturbed soils. However, all available D S (θ) models have bee

Time Domain Reflectometry Coil Probe Measurements of Water Content during Fingered Flow

Autor: Henrik H. Nissen, Ole H. Jacobsen, L. W. de Jonge, Per Moldrup

Publikováno v: Soil Science Society of America Journal. 63:493-500

The study of fingered flow and other unstable flow phenomena in soil requires a nondestructive technique for measuring changes in volumetric water content (θ) with high temporal and spatial resolution. In this study, a small-scale time domain reflec

The distribution of moisture, degradable C, and N after direct injection of slurry can affect the turnover and plant availability of slurry N. This study examined effects of injection method, soil conditions, and slurry properties on the infiltration
