Soil Compaction Curve of an Oxisol Under Sugarcane Planted After In-row Deep Tillage

Abstract

Soil tillage that maintains the productivity of sugarcane plantations, providing an area for the root development and without traffic on crop rows, has given rise to new technologies in rural areas. the purpose of this study was to evaluate the soil physical properties in two sugarcane plantations, one of which was prepared with deep tilling and the other with conventional tillage. the experiment was conducted in lençóis paulista, São paulo State. Soil penetration resistance and relative density were analyzed. the cone index was lower in deep-tilled soil without traffic in all layers, than in deep-tilled soil with traffic and in conventional tillage. In both tillage treatments, the relative density values were acceptable in the 0.00-0.15 m soil layer, but considered detrimental for sugarcane development in the 0.15-0.30 and 0.30-0.45 m layers.

Root growth and crop performance of soybean under chemical, physical, and biological changes after subsoiling

“…In no‐tillage, there is absence of soil tillage and heavy machine traffic over time, favoring the natural reconsolidation of soil particles (Reichert, Suzuki, Reinert, Horn, & Hakansson, 2009). Thus, subsoiling could be required to decrease soil density (Marasca, Lemos, Silva, Guerra, & Lanças, 2015; Souza, Souza, Cooper, & Tormena, 2015). In Red Latosol, with clayey texture the subsoiling positively affected rice yield (Pinheiro, Stone, & Barrigossi, 2016), in red‐yellow latosol with sandy texture, there was a decrease in PR values caused by the subsoiling equipment's rod action (Gonçalves, Lopes, Cavalieri‐Polizeli, Fiedler, & Stahl, 2019).…”

Biogeographical patterns in fungal communities from soils cultivated with sugarcane

“…Research regarding sugarcane production is extensive, and includes studies of sugarcane production under no-tillage management (Marasca et al, 2015), the use of organic residuals as fertilizers (Pina et al, 2015), and possible plant rotation with legume (Park et al, 2010). There are a few studies regarding the interactions between sugarcane and microbial communities, but these have primarily focused on specific microbial groups such as endophytes (Mendes et al, 2007;Magnani et al, 2010;Stuart et al, 2010), and bacterial communities in the rhizosphere (Luvizotto et al, 2010).…”

Avaliação do sistema radicular da cana-de-açúcar (<i>Saccharum spp</i>.) sob diferentes quantidades de palha mantidas na superfície do solo

“…O intenso tráfego de máquinas pode aumentar a densidade e reduzir a porosidade do solo, além de aumentar a resistência à penetração (Otto et al 2011;Souza et al 2012;Marasca et al 2015), provocar redução da aeração do solo (Camargo e Alleoni, 2006) e diminuição no tamanho e continuidade dos poros (Souza et al, 2015;Głab, 2014;Kuncoro et al, 2014;Cherubin et al, 2016), além de alterar a estrutura anatômica de raízes de cana-de-açúcar (Souza et al, 2013).…”

“…Esse uso intensivo da mecanização pode prejudicar os atributos físicos do solo, aumentando a densidade e reduzindo a porosidade do solo, além de aumentar a resistência à penetração (Otto et al, 2011;Couto et al, 2012;Marasca et al, 2015), provocando limitação do crescimento radicular.…”
