Short summary

Determining the chemical composition of soil water can help to address questions concerning water transport and use. However, there are many observations of incompletely mixed soil water within various soil pore domains. We applied two contrasting waters to soil samples and then removed water from the soils with three sequential and increasing applied energy steps to assess soil water mixing and equilibration over time. We found it took more than 3 d for soil water to mix and equilibrate.
