“…Fidalski et al (2015) also found no difference between treatments, because σ p was highly variable. The average values for σ p for P were 7 % lower than for NVP at a layer of 0.00-0.10 m, and 29 % lower at a layer of 0.20-0.30 m. The reduction in σ p seen in P is associated with the type of soil tillage at the time the crop was planted and with root activity.…”

“…In Brazil, soil compression curves have been widely used to evaluate soil response in reference to different soil properties and management practices, such as tillage systems (Silva et al, 2002a,b;Veiga et al, 2007), grazed pasture and eucalyptus forest (Suzuki et al, 2015), orange orchard (Fidalski et al, 2015), Oxisols with different textures (Severiano et al, 2011), sugar cane crop (Pacheco and Cantalice, 2011;Pereira et al, 2015), pastures (Pires et al, 2012), coffee crop (Araujo-Junior et al, 2011;Pais et al, 2013), and agroforestry systems (Watanabe et al, 2016). Other studies have focused on investigating the methods applied in determination of σ p and pedotransfer functions (Dias Junior and Pierce, 1996;Imhoff et al, 2004;Cavalieri et al, 2008;Suzuki et al, 2008;Severiano et al, 2011;Silva and Lima, 2016).…”

ABSTRACT:In irrigated soils, a continuous state of high moisture reduces resistance of the soil to applied external forces, favouring compaction. The aim of this study was to evaluate the susceptibility to compaction of developed calcareous soils in irrigated annual and perennial cropping systems of the Apodi Plateau, located in the Brazilian semi-arid region. Four areas of irrigated crops were evaluated: banana after two (B2) and 15 (B15) years cultivation, pasture (P), and a corn and beans succession (MB), as well as the reference areas for soil quality and corresponding natural vegetation (NVB2, NVB15, NVP and NVMB). Samples were collected at layers of 0.00-0.10 and 0.20-0.30 m; and for B2 and B15, samples were collected in the row and inter-row spaces. The following properties were determined: degree of compactness (DC), preconsolidation pressure (σ p ), compression index (Cc), maximum density (ρ max ), critical water content (WC crit ), total organic carbon (TOC) and carbon of light organic matter (C lom ). Mean values were compared by the t-test at 5, 10, 15 and 20 % probability. An increase was seen in DC at a layer of 0.20-0.30 m in MB (p<0.15), showing the deleterious effects of preparing the soil by ploughing and chiselling, together with the cumulative traffic of heavy machinery. The TOC had a greater influence on ρ max than the stocks of C lom . Irrigation caused a reduction in Cc, and there was no effect on σ p at field capacity. The planting rows showed different behaviour for Cc, ρ max , and WC crit, , and in general the physical properties displayed better conditions than the inter-row spaces. Values for σ p and Cc showed that agricultural soils display greater load-bearing capacity and are less susceptible to compaction in relation to soils under natural vegetation.

“…Bracchiaria), between the rows of fruit has become widespread, mainly with the aim of minimising soil loss due to erosion. In this case, the crop is periodically cut between the rows of fruit, which also results in the continuous input of residue to the soil surface (FIDALSKI et al, 2015). In addition to the input of plant residue, there is a contribution from the root system, mainly due to its intense renewal, which favours the lighter fractions of SOC (OLIVEIRA et al, 2016).…”

“…Bracchiaria), nas entrelinhas das frutíferas visando principalmente minimizar as perdas de solo por erosão. Neste caso, são realizados periodicamente o corte da cultura nas entrelinhas das fruteiras, o que também promove o aporte contínuo de resíduos sobre a superfície do solo (FIDALSKI et al, 2015). Assim, além do aporte via resíduos vegetais, também há contribuição do sistema radicular, principalmente, devido sua intensa renovação, que favorece as frações mais leves do COS (OLIVEIRA et al, 2016).…”

Usage and management alter the dynamics of soil organic carbon (SOC). The aim of this study was to compare the CO2 emissions in a Typic Humudept under different uses, and to relate the effects of CO2 emissions to the organic carbon content of the soil. Soil samples were collected from the 0-0.05, 0.05-0.10, 0.10-0.15 and 0.15-0.20 m layers under the following agricultural systems: no-tillage (NT), conventional (CT) and fruit orchard (FO). Samples were also collected from an area of native forest (NF) adopted as reference. The variables under evaluation were CO2 emissions and SOC content. Interaction between the usage or management systems and the soil layers influenced CO2 emissions in the soil. However, there was a difference in CO2 emissions between the soil layers under NF and CT only. In the 0-0.20 m layer, there was no difference in CO2 emissions under FO or CT, however these were greater than under NF or NT. In turn, the emissions under NT were lower than under NF at this layer. Furthermore, the systems with greater CO2 emissions showed less SOC. As such, in a Typic Humudept, the no-tillage management system results in reduced CO2 emissions. Greater SOC mineralisation has a direct impact on higher CO2 emissions.

“…Além de provocar o aumento da densidade do solo e da resistência mecânica à penetração, a compactação reduz a porosidade total, tamanho e conectividade dos poros(DIAS JUNIOR, 2000;KUNCORO et al, 2014;MENTGES et al, 2016;OBOUR et al, 2017). SORACCO et al(2015) observaram que estes efeitos da compactação do solo na configuração dos poros persistiram por um período de dois anos após o tráfego de máquinas.…”
