Abstract:
... Understanding the magnitude and variability of water and solute fluxes in the vadose zone is required to assess the risk of potential contamination of ground water resources. In this study, the long-term (>30 yr) movement of a Cl tracer applied to the soil surface is quantified. In 1966, granular KCl was applied to the surface of nine 6 by 90 m plots at a field site near Saskatoon, Saskatchewan. A ...
