Alterações físicas e químicas de um Argissolo amarelo sob diferentes sistemas de uso e manejo

Abstract: As alterações nas condições químicas do solo em virtude de diferentes sistemas de manejo com cana-de-açúcar podem causar modificações na dispersão de argila e no estado de agregação do solo. Estudaram-se os efeitos de diferentes sistemas de manejo com cana-de-açúcar nas propriedades físicas e químicas de um Argissolo Amarelo Coeso, selecionando-se quatro sistemas de uso e manejo, constituídos de uma área não irrigada, uma área irrigada, uma com aplicação de vinhaça e uma sob floresta nativa como condição origi… Show more

“…according to camilotti et al (2005), the pressure of the heavy tractor and harvester traffic, as well as of agricultural implements in the crop inter-rows causes compaction and affects soil structure and root growth, reducing yields and the lifetime of the crop to a greater or lesser extent, according to the conditions. the intensity at which soil physical properties under sugarcane are degraded varies widely and depends on the natural soil characteristics (dominy et al, 2002;Silva et al, 2005;centurion et al, 2007;luca et al, 2008), the soil tillage system (camilotti et al, 2005), cropping system (Maia & ribeiro, 2004b), harvesting processes (Souza et al, 2005;luca et al, 2008), soil conditions when farming operations are carried out (ralisch et al, 1994), and the type of fertilization (Maia & ribeiro, 2004b;Silva et al, 2006a). the main changes observed in the soil consisted of a drop in organic matter content (oM) (centurion et al, 2007; luca et al, 2008), structural degradation evidenced by an increase in soil bulk density (Souza et al, 2005;camilotti et al, 2005;centurion et al, 2007), a decrease in macroporosity (Silva et al, 2005;centurion et al, 2007), as well as increased soil penetration resistance (Souza et al, 2005;Brito et al, 2006;iaia et al, 2006;Souza et al, 2006) & gardner, 1963;Beutler & centurion, 2004a,b;Beutler et al, 2006) and macroporosity lower than 0.10 m 3 m -3 (centurion et al, 2007), are restrictive and can impede root growth and development.…”

“…Os maiores valores da razão argila fina/argila total na camada de 0,4-0,8 m em todos os solos estudados foram atribuídos à presença expressiva de cerosidade nas unidades estruturais desta camada, verificada na descrição do perfil do solo em campo (Silva, 2003).…”

“…A camada de 0,2-0,4 m dos solos cultivados apresentou estrutura em blocos angulares e subangulares, enquanto o solo da mata apresentou estrutura predominantemente granular, com os agregados mais arredondados (Silva, 2003). Rocha et al (2002), trabalhando com várias classes de solos, verificaram que solos com estrutura em blocos apresentaram maior ângulo de atrito interno e maiores valores de resistência do solo ao cisalhamento direto.…”

“…The decrease of the coastal tableland soil quality after the substitution of the forest by agricultural use, considering quantifications of its superficial and subsuperficial horizons, has been reported in specific studies, with obvious effects on the organic matter pools and associated variables (cation exchange capacity, water stable aggregates and average aggregate diameter) (SILVA et al, 2006a;SILVA et al, 2006b;COSTA et al, 2009;SANT'ANNA et al, 2009;FERNANDES et al, 2011;PACHECO;CANTALICE, 2011), however there is a lack of studies including a wider geographical sampling.…”
