“…Another important number of the analyzed publications includes less disturbed soils located inside the cities, especially in parks and agricultural zones (e.g., Aniceto and Horbe, 2012;Putrino, 2017) or in peri-urban areas with low density of occupation (e.g., Santos Júnior et al, 2012;Mysczak, 2013;Costa et al, 2019). This approach corroborates with the definitions of Hollis (1991), Lehman and Stahr (2007), Rossiter (2007) and Hazelton and Murphy (2011) (Table 1), which comprise more altered as well as more preserved soils located within urban and suburban areas.…”

“…Three methodological propositions, available in Portuguese in four publications (Curcio et al, 2004;Pedron, 2005;Pedron et al, 2006;Costa, 2018), and in English in one publication (Costa et al, 2019), deserve a highlight because they bring significant Rev Bras Cienc Solo 2022;46:e0210124 contributions for the study of Anthropogenic soils worldwide, especially regarding their mapping and classification. Pedron (2005) and Pedron et al (2006) proposed an Urban Land Use Potential System, inspired in technical systems applied in rural areas, in order to employ the maximum potential of urban soils for human activities and avoid land degradation.…”

“…Costa (2018) and Costa et al (2019) proposed a protocol for urban soils description and the incorporation of qualifiers to describe a Technosol (IUSS Working Group WRB, 2015), based on the study of soils of a medium-sized city (Santa Maria -RS). The protocol for field description incorporates morphological variables that highlight the heterogeneity and the influence of anthropic interventions in urban soils.…”

“…They introduce general concepts without focusing on the Brazilian production or in the specific properties or functioning of Brazilian and/or tropical urban soils (Pedron and Dalmolin, 2002;Pedron et al, 2004;Pedron et al, 2007;Ladeira, 2012a,b;Pedron et al, 2019). Regarding the methodological proposals, the more significant publications include a classification system of Anthroposols (including urban soils) by Curcio et al (2004), a land use potential system for urban soils by Pedron (2005) and Pedron et al (2006), and a protocol of qualifiers' description of urban soils by Costa (2018) and Costa et al (2019), the latter being the only one in English.…”

“…However, physical and/or chemical analyses are commonly performed only in the topsoil (0.05, 0.10, 0.20 or 0.30 first meters), which are, in general, arbitrarily pre-defined depths. Laboratory analyses are more common in publications centered on contamination (e.g., Moura et al, 2006;Gonçalves, 2011;Aniceto and Horbe, 2012;Cervi et al, 2014;Barbosa and Correa, 2015;Dias, 2017;França et al, 2017;Dala-Paula et al, 2018;Milhome et al;2018;Putrino and Ladeira, 2019), but they are also available in studies focused on genesis and characterization (Santos Junior and Lima, 2012;Teixeira et al, 2019), classification (Costa et al, 2019) and fauna and flora (Patucci et al, 2017;Vale et al, 2017;Lima et al, 2018). The pH, soil organic carbon (SOC), exchangeable cations, CEC and particle size are the most frequent analyses presented in the results.…”

This study analyzes the scientific production about soils within cities in Brazil, the most populous country of Latin America, to highlight significant patterns and contributions and point out gaps and future challenges. A more robust literature about urban soils in Brazil started in the 90´s decade and has intensified since 2015. Papers are mostly published in Portuguese, majority performed in cities with more than 500,000 inhabitants, many of them located in the Southern and Southeastern regions, and mainly focused on soil characterization, classification, mapping and/or contamination. Important methodological propositions (related to classification and land potential) and morphological, physical and chemical results are published. Urban soils formed from landfills are the most common, but soils developed from irregular zones of waste disposals are also frequent, showing the deficiency of proper waste management in developing countries. Properties such as pH, base saturation, soil organic matter and P amounts tend to be higher in soils marked by the addition of earthy materials and solid waste than in soils developed from the process of cutting, which commonly exposes the acid and deep saprolite of the tropical and subtropical zones. Although the attention on the Brazilian urban soils has grown in the last years, more studies, with a higher variety of morphological and analytical data, still have to be performed to obtain more representative results. Systematization of concepts, terminologies, and methodologies is also necessary, allowing a more complete understanding of the soils. In addition, the incorporation of a classification key of Anthropogenic soils, including urban soils, in the Brazilian official classification system seems urgent. Finally, it is relevant to foment international publications about the Brazilian urban soils, allowing a wider comparison between the produced data and the results obtained worldwide.
