| Summary: | <p>Boreal ecosystems comprise one-tenth of the world's land surface and contain
over 20 % of the global soil carbon (C) stocks. Boreal soil is unique
in that its mineral soil is covered by what can be quite thick layers of
organic soil. These organic soil layers, or horizons, can differ in their
state of decomposition, source vegetation, and disturbance history. These
differences result in varying soil properties (bulk density, C
concentration, and nitrogen concentration) among soil horizons. Here we
summarize these soil properties, as represented by over 3000 samples from
Interior Alaska, and examine how soil drainage and stand age affect these
attributes. The summary values presented here can be used to gap-fill large
datasets when important soil properties were not measured, provide data to
initialize process-based models, and validate model results. These data are
available at <a href="https://doi.org/10.5066/P960N1F9">https://doi.org/10.5066/P960N1F9</a> (Manies, 2019).</p> |
