“…In Santa Catarina State, the conventional tillage system (CTS) is the dominant system used to grow onion (MENEZES JÚNIOR et al, 2014). Therefore, soils under this management are intensively degraded by the use of chisel and rotary tiller (EPAGRI, 2013;LOSS et al, 2015) Brazilian Journal of Agriculture v. 96, n.3, p. 496 -509, 2021 DOI: 10.37856/bja.v96i3.4285 498 which causes water, nutrients and soil losses by erosion (PANACHUKI et al, 2011) and can negatively affect soil physical properties (ARCOVERDE et al, 2019).…”

The objective of this study was to evaluate soil physical properties under different cropping systems for onion. The study was conducted on an Inceptisol in Ituporanga, Santa Catarina state, Brazil. We evaluated eight cropping systems for onion: T1: maize-onion succession; T2: common vetch-maize/rye+fodder radish-onion-maize/rye+fodder radish-common bean; T3: rye-onionmaize/black oat-maize; T4: onion-velvet bean succession; T5: rye-onion-millet/black oat-onionmillet; T6: rye-onion-velvet bean succession; T7: onion-velvet bean+millet+sunflower succession.Treatments from T1 to T7 were conducted under no-tillage system (NTS) and T8: maize-onion succession under a conventional tillage system. We used the randomized complete block design, with five replications. Undisturbed soil samples were collected at the 0-5, 5-10 and 10-15 cm soil layers and we evaluated the following soil physical properties: geometric mean diameter of aggregates, total porosity, macroporosity, microporosity, bulk density and the ratio macroporosity/ total porosity. The data analysis was performed using univariate statistics, principal components analysis (PCA) and cluster analysis (CA). Based on the cropping systems characteristics, the CA divided them into three groups: group 1: T7; group 2: T1, T2, T3, T4, T5, T6; and group 3: T8. T8 showed evidence of soil physical quality deterioration at the soil surface, T7 presented the best soil physical properties.

“…Despite this, sugarcane is a species that seems to be more tolerant to soil compaction than other crops (SÁ et al, 2016) and, according to Arcoverde et al (2019d), even if cultivation in soil with some restriction or physical impediment, such effects are mitigated when it is subjected to no-tillage, instead of reduced tillage, since the improvement of its physical quality and preservation of soil moisture is reflected in the productivity of cultivars, in sugarcane plant (ARCOVERDE et al, 2019a;ARCOVERDE et al, 2019d).…”

“…The use and the soil management to implement farm systems can negatively impact them due to adopting an agricultural model that does not prioritize natural resources' rational use (ARCOVERDE et al, 2019a). These impact changes in properties and physical processes in chemical and biological order (ARCOVERDE et al, 2015).…”

Conservation systems for soil management are increasing for sugarcane cultivation. However, there is still little information about the effects of this management on soil physical quality at different scales, fundamental to agricultural activity sustainability. The objective was to evaluate the variability and spatial dependence of Oxisol physical attributes under no-tillage and reduced-tillage in sugarcane cultivation. Undeformed soil samples were collected 45 days after sugarcane planting, using a regular mesh with intervals of 7.5 m, totaling 32 points in each tillage system. Soil density, resistance to penetration, total porosity, macroporosity, and microporosity were determined in two depths (0-0.10 and 0.10-0.20 m). Using geostatistical methods was verified in both tillage systems that spatial dependence in the two depths, prevailing in the layer 0.00-0.10 m, in no-tillage, strong dependence with the adjusted spherical model reduced preparation, moderate dependence, with exponential adjustment. In the 0.10-0.20 m layer, spatial dependence was an inversion and adjusted model, i.e., in no-tillage, there was moderate dependence, exponential adjustment, reduced preparation, strong dependence, and spherical adjustment. Linear correlations demonstrate how much soil physical attributes are related to management conditions and present behaviors like isoline cartogram.

Lithic soils in the semi-arid region of Brazil: edaphic characterization and susceptibility to erosion

et al. 2022

Soils (Leptosols or Epileptic Regosols) with lithic contact at a depth of 50 cm occupy almost 20% of the Brazilian semi-arid region. These lithic soils are susceptible to erosion due to faster saturation of water-holding capacity during rainfall, which accelerates the beginning of runoff. However, erosion traits of lithic soils in the semi-arid region of Brazil are less studied. The aim of this study was to characterize the soil and landscape attributes in areas with Neossolos Litólicos (Entisols) in the Caatinga biome to identify region of high susceptibility to erosion. Results showed that the soils were characterized by a sandy texture, soil structure with poor development and low content of organic carbon. These attributes increase susceptibility to erosion and reduce water storage capacity, especially in the states of Ceará and Sergipe. In these states, the content of rock fragments in the soil reaches 790 g/kg. High contents of silt and fine sand, high silt/clay ratio, predominance of Leptosols and strong rainfall erosivity were observed in Piauí and northwestern Ceará. A very high degree of water erosion was observed in the states of Pernambuco and Paraíba. Despite the low degree of erosion observed in the state of Bahia, it is highly susceptible to erosion due to the predominance of very shallow soils, rugged relief and high values of rainfall erosivity. Lower vulnerability was observed in the state of Alagoas because of its more smoothed relief, greater effective soil depth, thicker A horizon of soil and lower rainfall erosivity. In general, the characteristics that intensify the susceptibility to erosion in the Caatinga biome are those soil structures with poor development or without aggregation, low contents of organic carbon, high contents of silt and fine sand, high values of silt/clay ratio and rugged relief in some regions. This study collected information contributing to a better characterization of soils with lithic contact in the semi-arid region of Brazil. In addition, regions with a higher susceptibility to erosion were identified, revealing insights that could help develop strategies for environmental risk mitigation.
