Soil

Soil data have been collected by Jérémy Lischtein (pers. com.) for Paracou and Tapajos. They include:

Silt, clay, and sand fraction in percent for Paracou (Van Langenhove et al. (2021): Table 1, slope SLD soils, 0-30 cm and Gourlet-Fleury et al. (2004): Table 3, deep ferralitic soils, 0-40 cm) and Tapajos (Silver et al. (2000): Table 5, gradient position 350).
Soil Organic Carbon (SOC) in percent for Paracou (Van Langenhove et al. (2021): mean of slope SLD soil values (0-30 cm depth) in Tables 2-3, dry and wet seasons averaged) and Tapajos (Quesada et al. (2010): Table S2, 0-30 cm depth).
Dry Bulk Density (DBD) in for Paracou (Van Langenhove et al. (2021): mean over 0-30 cm depth for superficial lateral drainage (SLD) slope soils) and Tapajos (Silver et al. (2000): mean for clay soils (0-10 cm depth) from Table 1, gradient positions 350 and 400).
pH for Paracou (Van Langenhove et al. (2021): mean of slope SLD soil values 0-30 cm depth in Table 1) and Tapajos (Quesada et al. (2010): Table S2, 0-30 cm).
Cation Exchange Capcity (CEC) in miliequivalent per 100 grammes for Paracou (Sabatier et al. (1997): Table 2, SLD soils, 0-30 cm) and Tapajos (Quesada et al. (2010): Table S2, 0-30 cm depth).
Soil depth in metre based on no drainage barrier to at least 12 m depth (Nepstad et al. 2002) for Tapajos.
