Soil Physical Laboratory Methods – Procedures used at the Soil Physics Laboratory 2000-2020

This report presents the protocols and methods used 2000-2020 in the Soil Physics Laboratory at the Department of Soil and Environment, Swedish University of Agricultural Sciences, Uppsala, Sweden. The aim is to provide a transparent description of procedures used and to provide links and references to quality assurance and standards. Brief theoretical background and concepts are included for the different methods and procedures. New analytical techniques, such as integral suspension pressure (Pario) and laser diffraction (Horiba) methods for particle size distribution and pF laboratory station (Ecotech) for water retention properties, have been tested since 2020, but are not included in this report. For these, see technical manuals and scientific reporting.
