Utility of rhizon soil moisture samplers in low conductivity soils.


The difficulty of obtaining soil water samples from glacial till became apparent when large suction lysimeters failed to collect a volume sufficient for strontium analysis. Poor sorting and unpredictable pore space patterns in glacial till made selecting a suitable installation site for the lysimeters difficult. When the samplers were able to be installed, they yielded only very small sample volumes. This study explores alternative pore water sampling methods for obtaining volumes of at least 50 ml from low conductivity soils. Smaller rhizon samplers function similarly to suction lysimeters, but the radius of influence is much smaller, therefore they collect a sample more representative of pore water at the depth the sampler is placed at. The use of smaller rhizon samplers in less conductive soils can lend additional understanding to the transport of pollutants in glacial till and other similar soils. The ability to collect accurate samples from specific soil depths can aid in the understanding of pollutant transport rates, transfer of snow chemistry to soil water and subsequently groundwater, and overall soil saturation levels.
