Última Soil physical properties and soil organic carbon content in northeast Brazil: long-term tillage systems effects Scientia Agricola Oliveira,Fernanda Cristina Caparelli; Ferreira,Gabriel William Dias; Souza,João Lucas Santos; Vieira,Matheus Emannuel Oliveira; Pedrotti,Alceu. ABSTRACT Concerns about the negative effects of agriculture on soil physical quality and soil organic carbon (SOC) pools have spurred on the adoption of conservation tillage systems in tropical regions. This study aimed to evaluate the long-term impacts (16th year) of conventional (CT), minimum (MT) and no-tillage (NT) practices and different cover crops (sunn hemp and a bean/millet sequence) on soil physical properties and SOC content of a corn cultivated Ultisol in the northeast of Brazil. Soil bulk density (Bd), soil penetration resistance (SPR), soil aggregation, and total aggregate-associated carbon (C) (4-2 mm) were evaluated. Tillage practices exerted strong control on soil physical properties and total aggregate-C content but were influenced by...
