Soil chemical properties associated with PFT tree species in the Laipuna Core Plots at 600 and 1200 m asl

The dataset includes chemical properties of the mineral soil associated with the PFT trees species of the core plots of the Laipuna Natural Reserve. The samples were taken during the sampling campaign in 2023. Respresentative samples were taken from the mineral soil at five locations close to each tree from 0-10 cm mineral soil depth, bulked in the field, dried at 40 °C at the research station and transported to Germany for laboratory analyses. Total carbon, nitrogen and sulfur were measured by elemental analysis via thermal combustion in milled aliquots. Available P was measured in the < 2mm soil fraction after extraction by the Olsen method with 0.5 M NaHCO3 and measurement by continuous flow analysis.
