Fig. 3. Potential C mineralization in experimental plantations at La Selva Biological Station, Costa Rica, determined as CO2–C released during laboratory incubations of soil from 15-yr-old plantations and abandoned pasture and mature forest reference sites. Data are for the 0–15 cm depth. Hyal = Hyeronima alchorneoides; Pema = Pentaclethra macroloba; Pipa = Pinus patula ssp. tecunumanii; Viko = Virola koschnyi; Vofe = Vochysia ferruginea; and Vogu = Vochysia guatemalensis. Reference sites were not included in the ANOVA. Error bars are standard errors.
