Fluorescence Characteristics of Dissolved Organic Matter (DOM) in Percolation Water and Lateral Seepage Affected by Soil Solution (S-S) in a Lysimeter Test. [PDF]

open access: yesSensors (Basel), 2019
The composition and structure of dissolved organic matter (DOM) are sensitive indicators that guide the water infiltration process in soil. The DOM chemical composition in seepage affects river water quality and changes soil organic matter (SOM). In this

Soil Solution Analysis With Untargeted GC–MS—A Case Study With Different Lysimeter Types

open access: yesFrontiers in Earth Science, 2021
Surface-sourced organic compounds in infiltrating waters and percolates are transformed during their belowground passage. Biotic and abiotic processes thereby lead to continuously changing chemical environments in subsurface compartments.

Measuring very negative water potentials with polymer tensiometers: principles, performance and applications [PDF]

open access: yes, 2009
In recent years, a polymer tensiometer (POT) was developed and tested to directly measure matric potentials in dry soils. By extending the measurement range to wilting point (a 20-fold increase compared to conventional, water-filled tensiometers), a ...
