Study #279: Characterizing Solute Movement in Coarse-textured, Leaching-vulnerable Soils with Zero-tension Column Lysimeters

A Physically Derived Water Content/Permittivity Calibration Model for Coarse-Textured, Layered Soils

to try and ascertain the relative importance of different soil properties for calibration. This approach has good Many empirical formulas relating TDR-measured permittivity (Ka) utility for finding simple and practical equations that can to volumetric water content ( ) have been presented owing to the lack of a robust and accurate physically derived model describing this be used to estimate . H...

Compaction of Coarse-Textured Soils: Balance Models across Mineral and Organic Compositions

Soil bulk density (BD), degree of compactness (DC), maximum bulk density (MBD), and critical water content (CWC) at which MBD is reached are commonly used to characterize soil compaction, and can be predicted from soil texture and organic matter content, omitting other components such as sand sub-classes and soil cementing agents and potential biases such as data redundancy and sub-compositiona...

Applicability of rare earth element oxides as a sediment tracer for coarse-textured soils

A leaching experiment using a mixture of five REE oxides and gravelly, sandy loam soils was conducted to examine the applicability of the REE oxides as a sediment tracer for coarse-textured soils. The experiment showed little leaching of the oxides and an enrichment of various size classes of soil particles with the oxides, which reflected the strong binding capability of the REE oxides with th...

Comparison of Experimentally and Theoretically Determined Infiltration in Coarse Textured Soil

Though it is vital to estimate infiltration as one of the key factors in effective management of water resources, only few studies have been carried out either to determine the infiltration or to compare the performance of infiltration models for coarse textured soils. Thus, the present study was conducted to accomplish two objectives. First to estimate the Horton’s infiltration model parameter...
