Author(s): SAGRILO, E.; JEFFERY, S.; HOFFLAND, E.; KUYPER, T. W. Soil amendment with pyrogenic organic matter (PyOM), also named biochar, is claimed to sequester carbon (C). However, possible interactions between PyOM and native soil organic carbon (SOC) may accele... ... |
Author(s): TONUCCI, R. G.; GARCIA, R.; NAIR, V. Agroforestry systems have the potential to enhance carbon (C) sequestration in soil compared with treeless (agricultural) systems (Montagnini & Nair, 2004). When one type of vegetation is replaced wit... ... |
