Retention and hydrolysable fraction of atmospherically deposited nitrogen in two contrasting forest soils in Switzerland

Claire Guenat, Isabelle Morier Jaquet

Nitrogen (N) from atmospheric deposition has been shown to be mainly retained in the organic soil layers of temperate forest ecosystems, but the mechanisms and the physico-chemical fractions involved are still poorly defined. We performed a hot-acid hydrol ...
