Field evaluation of passive capillary samplers in monitoring the leaching of agrochemicals

Creator:

Brandi-Dohrn, Florian M.

Abstract:

Soil solution samplers have certain inadequacies that limit their range of possible applications. Passive Capillary Samplers (PCAPS), which apply suction to the soil pore-water via a fiber glass wick, have shown promising results in preliminary experiments in regard to collection efficiency of water and of bromide tracers. The objectives of...

A predictive model for time domain reflectometry soil water content and salinity measurements

Creator:

Flugstad, Benjamin A.

Abstract:

Soil water content and water potential are two important parameters in determining the status of water in the soil. Improvement in the ability to measure these parameters by way of increased speed, accuracy, resolution, imaging volume, ease of automation, as well as reduced calibration requirements and reduced soil disturbance would...
