Virtual Seminar: Soil Water Drainage Measurement and Soil Water Sampling
Accurate quantification of solute (e.g. nutrient, pesticide, pathogen) fluxes through the soil has traditionally been difficult, requiring the accurate measurement of both the soil water flux (drainage) and the concentration of the solute in the soil water. This virtual seminar will discuss several techniques for measuring soil water drainage including water balance residual, zero tension pan lysimeters, static tension wick lysimeters, small scale controlled tension lysimeters, and large scale lysimetry. We will focus on the merits, drawbacks, and relative cost of each drainage measurement technique. The presentation will also cover methods of collecting soil water for solute concentration analysis including porous suction cups and plates. Consideration will be given to the sorption effects due to the chemical composition of the porous cup/plate, and limitations in effective sampling range due to the air entry potential of the porous material.
