Compositional changes of dissolved organic matter during high flow events in headwater catchments along a gradient of climate and land use

Comptes Rendus. Géoscience
High flow events in headwater catchments are associated with changes in the dissolved organic matter (DOM) composition. The aim of this work was to determine whether these changes are characteristic of headwater catchments and similar to what has been ...

The Influence of Different, Long-Term Fertilizations on the Chemical and Spectroscopic Properties of Soil Organic Matter

Agronomy
Currently, revealing soil management strategies that store the maximum atmospheric CO2 in the soil is a major issue. This is best explored by investigating long-term experiments, like the Skierniewice (Poland) field trial, established in 1921 on sandy ...
