“…Essa pobreza da serapilheira de eucalipto tem sido atribuída à sua eficiente ciclagem bioquímica (Gama-Rodrigues & Barros, 2002). Baixos teores de nutrientes no material vegetal, geralmente, correlacionam-se com baixas taxas de decomposição (Cobo et al, 2002). Também, os materiais com elevada relação C/N (> 25) e altos teores de lignina e polifenóis sofrem decomposição mais lenta (Myers et al, 1994).…”

“…Although broccoli cultivation sequentially to cowpea resulted in seedling mortality and low yield (Schroeder et al, 1998), adjusting the management of the leguminous biomass may reduce the need for compost on organic agriculture. However, N supply to crops by means of N mineralization on green manure residue must be synchronized with crop N demand (Thönnissen et al, 2000a(Thönnissen et al, , 2000bCobo et al, 2002b;Murphy et al, 2004), and it is necessary that biomass addition time and crop growth rate match (Lahti & Kuikman, 2003).…”

“…Rotation with leguminous green manure can result in significant inputs of nitrogen into the soil-plant system and subsequent crops (Boddey et al, 1997;Fillery, 2001;Ramos et al, 2001;Cobo et al, 2002b). N mineralization rate from leguminous residues can be very high under tropical conditions (Tian et al, 1992;Cobo et al, 2002a).…”

“…N mineralization rate from leguminous residues can be very high under tropical conditions (Tian et al, 1992;Cobo et al, 2002a). High N immobilization or losses through leaching (Fillery, 2001) and or volatilization (Janzen & McGinn, 1991) can occur if N is released when crop N demand is smaller than the N supply (Cobo et al, 2002b;Lahti & Kuikman, 2003). This release is affected by weather conditions, soil management, crop management practices (Fillery, 2001;Palm et al, 2001;Thompson & Fillery, 2002) and residue properties.…”
