Trees and grass contribution to soil organic carbon in agroforestry systems. 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... ... Repository: BDPA Publication year: 2015
Impact of organic fertilization on establishing an agroforestry system in a semi-arid Brazilian region. Author(s): POMPEU, R. C. F. F.; TONUCCI, R. G.; BUENO, L. G.; CRUZ, G. dos S. da; MARANGUAPE, J. S.; ANDRADE, H. A. F. de; SOUZA, H. A. de Abstract: Improving soil fertility with organic sources is crucial, particularly in degraded regions. Organic fertilizers, when integrated into systems, provide cost-effective solutions. This study ai... ... Repository: BDPA Publication year: 2023
