“…A dessecação aos 15 DAS+RF resultou num menor valor de N na planta de arroz no estádio fenológico V 3 , para o ano agrícola de 2010/11, evidenciando uma redução de 11% em relação ao tratamento pousio. Esse comportamento pode ser atribuído à maior relação C/N nos resíduos vegetais do azevém em função da maior proporção de colmos nos estádios fenológicos mais adiantados (TEIXEIRA et al, 2011), diminuindo, assim, a velocidade de decomposição dos resíduos vegetais aos 15 DAS+RF, quando comparado aos demais tratamentos.…”

“…In addition, the increase in air temperature, and consequently in soil temperature, as well as rainfall, that occurred during the experiment may have contributed to increase breakdown of residues by microorganisms (Figures 1a and 1b) (Teixeira et al, 2011(Teixeira et al, , 2012 (-kt) ) to the values of remaining dry matter (DM), total organic carbon (TOC), lignin (Lig), cellulose (Cel), non-structural biomass (Bio), nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg); decomposition constant (k); and half-life (t ½ ) of each compartment and R 2 values for the residues of weeds (WD), black oat (BO), rye (RY), oilseed radish (RD), oilseed radish + black oat (RD + BO), and oilseed radish + rye (RD + RY) deposited on the onion row Rev Bras Cienc Solo 2016;40:e0150099 ) and C/N ratio value (22), and its low Cel/Lig ratios (3) ( Table 1). Residues with high levels of lignin, and consequently higher Lig/N ratio values and lower Cel/Lig values, have slower decomposition, since lignin protects cell wall cellulose from microbial degradation (Berg and McClaugherty, 2008).…”

“…This occurred because Ca is part of the structural composition of the cell, acts as a cofactor in enzymes involved in ATP and phospholipid hydrolysis, and is a second messenger in metabolic regulation (Taiz and Zeiger, 2013). That results in an additional difficulty to its release from decomposing residues into the soil (Teixeira et al, 2011). The smallest remaining Ca content in the WD residue is due in part to a lower t ½ (34 days) in non-structural biomass (Table 2) and the low remaining C/N ratio (Table 3), which increased decomposition and thus intensified Ca release.…”

“…In Brazilian semi-arid region, there are reports of green manures phytomass additions ranging from 1.7 to 11 Mg.ha -1 (Massad et al, 2013), related to the species, soil fertility, climatic conditions, C/N and lignin/total N, among others (Pariz et al, 2011;Teixeira et al, 2011). However, the minimum quantities of biomass were not defined for the positive balance of addition and accumulation dry matter, carbon and nitrogen in the soil, to increase the soil or agroecosystems quality.…”
