Abstract: Surface roughness of the soil is formed by mechanical tillage and is also influenced by the kind and amount of plant residue, among other factors. Its persistence over time mainly depends on the fundamental characteristics of rain and soil type. However, few studies have been developed to evaluate these factors in Latossolos (Oxisols). In this study, we evaluated the effect of soil tillage and of amounts of plant residue on surface roughness of an Oxisol under simulated rain. Treatments consisted of the combin… Show more

“…Overall to 30 cm depth, soil moisture contents under NT treatments were significantly different than those under CT (Figure 3). In general, soils under NT store more water in the surface layer (Panachuki et al, 2015). The higher water retention in NT is attributed to the maintenance of cover crop on soil surface, which acts as a barrier, reducing water loss by evaporation (Ward et al, 2013).…”

“…Additionally, the long cycle and harvest of cotton during the dry months do not favor establishment of cover crops during the off season, which also reduces soil cover effectiveness for the following cropping season. Soil compaction is another challenge under NT systems, due to some heavy vehicular traffic under wet soil conditions (Freddi, Centurion, Beutler, Aratani, & Leonel, 2007;Panachuki, Bertol, Alves Sobrinho, Oliveira, & Rodrigues, 2015) leading to reorientation of particles and densification of soil (Taboada, Micucci, Cosentino, & Lavado, 1998).…”

“…The knowledge of micro relief or soil surface roughness can generate important information for interpretation of the effects caused by both human activities in function of the management adopted in the area (Panachuki et al, 2011;Panachuki et al, 2015), as by natural inclement weather as the climate, highlighting the need of studies to determine this parameter (Dalla Rosa et al, 2012;Tuo et al, 2016).…”
