  1. 1. Biogeochemistry and Peat Properties of Restored Peatlands

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Pelle Belaieff Kronborg; [2022]
    Keywords : Drainage; Bulk density; Nitrogen; Carbon; Stable isotopes;

    Abstract : Globally, peatlands comprise the most important soil organic carbon pool storing approximately one third of all terrestrial soil carbon.
