“…Organic coffee polyculture showed similar carbon stocks to low tropical forests in Guatemala (Schmitt-Harsh et al, 2012), medium semi-humid forest in Mexico (Orihuela-Belmonte et al, 2013), and other high covered agroforestry systems in Mexico, such as improved fallows, Taungya, and silvopastoral systems (Soto-Pinto et al, 2010;Soto-Pinto & Armijo-Florentino, 2014). Thus, the organic management could be much more important to increase not only the carbon in shade vegetation, but significantly, in the soil; litter deposition, humus content in the first soil layer, and the role of shade vegetation to preserve soil and carbon content are of paramount importance at landscape and global scales (Soto-Pinto et al, 2010;Häger, 2012;Palm et al, 2014).…”
