Abstract: -The aim of the present study was to evaluate the effects of cover crops on the soil's chemical fertility, in particular its carbon and nitrogen content, in a Typic Acrustox under conventional and no-tillage corn systems. We hypothesized that the no-tillage system associates with cover crops maintains or increases soil carbon and nitrogen stocks and enhance soil fertility. The no-tillage system did not present higher carbon and nitrogen stocks than conventional tillage, but resulted in higher concentrations of… Show more

“…Significant differences in soil C and N stocks were found between different cover crops grown in succession to corn in the same experimental plots evaluated in the present study (Carvalho et al, 2014b). The use of M. pruriens under no-tillage may enhance soil organic matter and, therefore, increase soil C and N stocks (Carvalho et al, 2014b). Moreover, the increase of the soil C/N ratio at 0-0.05-m depth, in the dry season, in plots with the addition of M. pruriens residues (C/N = 18), when compared to those with natural fallow (C/N = 9.4), may be another indicator of the increase in soil C, which is possibly attributed to the high concentration of aromatic compounds in the species (Carvalho et al, 2009;Talbot et al, 2012;Carvalho et al, 2014a).…”

“…The increase in C stocks in the soil depends on C and N inputs, residue decomposition, microbial biomass growth and activity, management practices, and soil and climatic factors (Cruvinel et al, 2011); soil organic matter is higher in the surface layer due to the accumulation of plant residues there (Carvalho et al, 2014b;Boddey et al, 2010). Significant differences in soil C and N stocks were found between different cover crops grown in succession to corn in the same experimental plots evaluated in the present study (Carvalho et al, 2014b). The use of M. pruriens under no-tillage may enhance soil organic matter and, therefore, increase soil C and N stocks (Carvalho et al, 2014b).…”

“…No bioma Cerrado os solos dominantes são Latossolos (Latossolos), sendo os SPD introduzidas em meados dos anos 80. Esses são bons fornecedores de matéria orgânica para o solo, a qual está presente em níveis médios entre (2 e 3 dag kg-1 ), sendo um componente fundamental para regular a fertilidade do solo e responsável por reservas de nutrientes (CARVALHO et al, 2014).…”

“…Appropriate land use and management help to mitigate greenhouse gases and global warming (Lal, 2004) as well as influence of soil organic C (SOC) dynamics and, obviously, the sustainability of agricultural lands (Devine et al, 2014). In Brazil, weathered soils are characterized by a natural low fertility, and most nutrient reservoirs and CEC mainly rely on organic matter stored in the soils (Carvalho et al, 2014). Losses of soil organic matter (SOM) with cultivation are directly linked to the rapid degradation of soil biological, chemical, and physical properties (Madari et al, 2005).…”
