“…This may be due to the period of time (one year) between tillage and soil sampling. Short-term effects of tillage are consistently reported in the literature (Reichert et al, 2009;Moraes et al, 2016).…”

“…However, used a medium texture soil in their experiment (a clay content between 15 and 35%). These differences with regard to the content of clay have a strong influence on the hydraulic conductivity of the soil, which may influence the absorption of water and consequently its development (Moraes et al, 2016;Nadei-Boldaji & Keller, 2016).…”

“…This system consists of stirring up the soil only in the sowing furrow (Palma et al, 2010;Botta, Tolon-Becerra, LastraBravo, & Tourn, 2010). It is also marked by the intense traffic of machines and equipments, which results in serious problems with soil compacting that may cause a loss in production (Moraes et al, 2016;Naderi-Boldaji & Keller, 2016;Botta et al, 2016).…”

“…Several studies have examined the effects of soil compaction in the development of plants in several types of soil, but they are not conclusive with regard to the values of soil density and resistance to penetration that are considered limiting factors since good moisture conditions may supplement the lower volume of soil used by the roots to supply the plant with water and nutrients (Oliveira et al, 2012;Gao, Whalley, Tian, Liu, & Ren, 2016;Moraes et al, 2016).…”

<b>Soybean productivity in Rhodic Hapludox compacted by the action of furrow openers

et al. 2018

ABSTRACT. The heavy traffic of machines in no-tillage systems causes problems as soil compaction and loss of crops productivity. The objective of this paper is to evaluate the productivity of soybeans in reference to furrow openers and the levels of soil compaction in two crops. The experiment was conducted on Rhodic Hapludox by tracing random blocks with subdivided parcels. The soil bulk density levels were laid out in the parcels (1.16, 1.20, 1.22, and 1.26 Mg m -3) and the furrowers in the sub-parcels (double disc and shanks). The resistance to penetration, depth of the furrow, mobilized soil area, final plant stands, height of plants, mean number of beans by pod, 1,000 bean mass, number of pods per plant and productivity of the culture were evaluated. The resistance to penetration increased with the levels of soil compaction regardless of the farming year and up to a depth of 0.20 m. In the first crop, higher productivity with the use of the shank was observed. In the second crop, the use of the shank resulted in an increase in depth of the furrow, mobilized soil, height of the plants and final stand of the plants, but this did not indicate an increase in productivity.

“…The adoption of a no-till or minimum tillage system, associated with crop rotation in the area under corn/beans is suggested as a strategy for improving the physical quality of the soil (Guedes Filho et al, 2013;Moraes et al, 2016). A sustainable alternative for the permanent pasture area is an integrated crop-livestock system with rotation of annual crops; however, it is essential to manage grazing height (Petean et al, 2010;Moreira et al, 2014).…”

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.
