“…All the studied soils were eutrophic, with a clear contribution of Ca 2+ and Mg 2+ in all the profiles, corroborating the results of Corrêa et al (2003), Alves et al (2005Alves et al ( , 2007, Galindo et al (2008) and Parahyba et al (2010). Profile 1 had the lowest base saturation (V) among the studied profiles, possibly due to the high rainfall in this region.…”

ABSTRACT:The semiarid region of northeastern Brazil has a large area occupied by Planosols, where in the State of Pernambuco these soils are mainly used for livestock farming and subsistence crops. The knowledge on these soils is limited, which compromises the understanding on their behavior, potentialities and limitations.This study aimed to analyze morphological, chemical, physical and mineralogical attributes of Planosols developed under different geoenvironmental conditions. Morphological descriptions and chemical, physical and mineralogical analyses were performed in four profiles of Planosols along a rainfall gradient. An increase in rainfall allowed for an increase in the clay content in the Bt horizon and a reduction in ESP, EC, Na + , CEC, S, pH (water and KCl) and soil density. Horizons A and E were thicker in Planosols in more humid environments. The increase in ESP associated with the presence of expansive minerals (smectite and vermiculite) allowed the development of a prismatic structure in Haplic Planosols and a columnar structure in Natric Planosols. The mineralogical assembly is indicative of poorly weathered soils. The mineralogical assemblies of the silt and clay fractions were similar in the different geoenvironments, while higher contents of easily alterable minerals were observed in the composition of the sand fraction in environments with a drier climate.

“…For example: 1) the Quilombolas mentioned excessive hardness of the PLhaeu (Table 1), but they did not mention the excessive presence of Na + , a limiting factor for agriculture in this area; 2) there were no comments relating geology to soil formation, although the soil mineralogy was not focused on in the study; 3) the Quilombolas showed a three dimensional perception of the soils (Toledo and Barrera-Bassols, 2009), perceiving the soil horizons as "natives", but this issue was not explored either; 4) some people who were interviewed emphasized the main characteristics of the soils present on their lands, sharing a common knowledge with the other people when guided freely on a general perception of MGQT lands. Regarding the absence of perception regarding the Na + of the PLhaeu, Alves et al (2005), who studied ceramic artisans of the Brazilian state of Paraíba, identified that people whose practice depends on detailed perception of consistency can distinguish soil consistency based on observation of the different taste the soils have when they contain different levels of salt. Thus, the subjectivism may result from the focus of research, sampling, and the intrinsic character of the local practices of land use, as Krasilnikov and Tabor (2003) highlight.…”

Quilombolas are Afro-brazilian rural peasants who descended from escaped slaves who tried to carve out territories of autonomy (called Quilombos) by collective organization and resistance. Despite many anthropological and ethnopedological studies, little research has been carried out to identify the agricultural practices and the knowledge of people who live in the Quilombos (Quilombolas). Peasant communities who live from land resources have wide empirical knowledge related to local soils and landscapes. In this respect, ethnopedology focuses on their relationship with local practices, needs, and values. We carried out an ethnopedological evaluation of the soils, landscape and land suitability of the Malhada Grande Quilombola Territory, aiming to examine the local criteria involved in land-use decision making, and evaluate the legitimacy of local knowledge. For this purpose, participatory workshops allowed environmental stratification of the Quilombolas into landscape units, recognition of soil types, and evaluation of land-use criteria. This approach was combined with conventional soil sampling, description, and analysis. The Brazilian System of Soil Classification and its approximations to the WRB/FAO system and the SAAT land evaluation system were compared with the local classificatory systems, showing several convergences. The Quilombolas stratified the local environment into eight landscape units (based on soil, topography, and vegetation) and identified eight soil types with distinct morphological, chemical, and physical attributes. The conventional soil survey identified thirteen soil classes, in the same eight landscape units, organized as soil associations. The apparent contradictions between local knowledge and Pedology were relative since the classification systems were established based on different criteria, goals, and sampling references. Most soils are only suitable for pasture, with restricted agricultural use, due to water or oxygen deficiencies. The current land use was only inconsistent with the technical recommendations when socioecological constraints such as the semiarid climate, land availability, and economic conditions for land management led to overuse of the land. Local knowledge demonstrated its legitimacy and allowed a useful and fruitful exchange of information with the academic view of soil-landscape interplays. Although mostly unknown by the scientific community, local knowledge proved capable of achieving social welfare and food security. In addition, a participatory survey proved to be a core factor for more grounded and detailed data collection on how Quilombolas decide land use on a local scale.

“…Neste sentindo ressalta-se que os conhecimentos em etnopedologia apresentam similaridades ao cientifico principalmente aos atributos observados, classes de solos e métodos de análise a campo (ERICKSEN ;ARDÓN, 2003;ALVES et al, 2005;BENASSI et al, 2009;PALACIO;ARRIAGA, 2005;DAWOE et al, 2012;ALTIERI, 2012;CARVALHO, 2016;PORTELA et al, 2015;NETO, et al, 2019). Ainda para diversos autores a aproximação das interpretações, locais e cientificas, sobre o solo contribui para uma gestão sustentável das terras, pois tanto as análises locais como as científicas são incompletas e estas podem ser complementares (BRIGGS et al, 1998;TALAWAR;RHOADES, 1998;ERICKSEN;ARDÓN, 2003;ALIER, 2014;ALTIERI, 2012;STRACHULSKI;FLORIANI, 2014).…”

O estudo tem por objetivo aproximar o conhecimento sobre solos de agricultores e cientistas através da correspondência de classes etnopedológicas e científicas. Foram entrevistadas vinte famílias de agricultores de Antonina e Morretes (PR) através da metodologia de diagnóstico participativo. As classes de solos identificadas foram ordenadas conforme as técnicas científicas formais. Foram abertos dois perfis complementares para cada classe etnopedológica para averiguar as correspondências entre as classes de terras nos municípios pesquisados. Para a classificação cientifica utilizou-se o Sistema Brasileiro de Classificação de Solos (SiBCS). Obteve-se como resultados a classe etnopedológica “Terra de Morro” que correspondeu às classes de solos CAMBISSOLO HÚMICO Distrófico típico e ARGISSOLO VERMELHO-AMARELO Distrófico típico, a terra “Sabão de Caboclo” correspondeu a GLEISSOLO HÁPLICO Tb Distrófico típico e GLEISSOLO HÁPLICO Ta Eutrófico típico, a “Terra Argilosa” correspondeu a CAMBISSOLO HÁPLICO Tb Distrófico típico e CAMBISSOLO HÁPLICO Ta Eutrófico típico, e a “Terra de Desmonte” correspondeu a CAMBISSOLO FLÚVICO Ta Distrófico típico e NEOSSOLO FLÚVICO Ta Eutrófico típico. Os sistemas de classificação de agricultores é voltando ás necessidades produtivas agrícolas, artesanais ou para construção de moradias, já o sistema de classificação de cientistas do solo o SiBCS aplicado tem objetivo geral e empregos em diversas áreas.
