Data from: Effects of tree functional traits on soil respiration in tropical forest plantations

The study covers four plantations stands of Acacia auriculiformis (A), Eucalyptus urophylla (E), Hopea odorata (H), and X. xylocarpa (X) through a sample plot (50 m x 50 m) in each stand from July 2015 until June 2016. Physical and chemical soil properties were collected at two depths (0-15 cm, 15-30 cm) at the beginning of the study (soil_properties_initial.csv). Additional samplings of topsoil pH, bulk density (BD, g cm-3), organic matter (OM, %), total carbon (TC, %), and nitrogen (TN, %) were conducted monthly (mo_yr) at five random locations (soil_properties_month.csv). Soil respiration (SR) was measured at the beginning of each month (mo_yr) at 12 locations (Point) within each species sample plot (Species) for ten hours (h_time) simultaneously with soil temperature (ST, C), air temperature (AT, C), relative humidity (RH), and soil moisture (SM, %) (soil_respiration.csv). The location of each soil respiration measurement point within the sample plots is provided as well (soil_respiration_location.csv). All trees within each sample plot were mapped (X, Y) and their stem basal area (BA_cm2) and height (H) were measured (stand_inventories.csv).
