Resumo: | The Pantanal comprehends a set of heterogeneous and biodiverse landscapes of esteemed environmental, economic and social value. The study of soils is effective to stratify and to understanding the operation of these environments. The purpose of this study was to characterize and compare soils of lake landscapes of the Pantanal: baías (freshwater lakes), salinas (alkaline lakes) and their respective levees (sandy ridges originally with forest vegetation). For this purpose, we carried out field work with sampling, in triplicate, of superficial soil layers in 12 representative areas of low and high Nhecolândia; analytical determinations of 26 soil attributes were performed, totaling 936 response variables and statistical analyses were performed in order to synthesize the data and present the results. In both landscapes, the fine sand fraction predominates in the soil granulometry. The textural class of the soils varied from very sandy, medium sandy and medium sandy for the baías; very sandy for the levees, with particle density related to the presence of quartz; and very sandy, medium sandy, medium clayey and clayey for the salinas. In the chemical attributes and organic matter, the baías stand out for higher potential acidity (H+Al), slightly high organic matter contents and availability of metal ions, especially Fe; in the levees, higher average remaining phosphorus (Prem) are more evident; while the saline lake soils are related to more alkaline pH values, high base saturation and high Sodium Saturation Indices (ISNa). Salinas landscapes presented the highest data variability and have soil attributes that refer to the action of different environmental processes. |

O estudo dos solos é efetivo para estratificar e compreender o funcionamento desses ambientes. Objetivou-se caracterizar e comparar solos de paisagens lacustres do Pantanal Sul-Mato-Grossense: baías (lagos de água doce), salinas (lagos alcalinos) e suas respectivas cordilheiras (cordões arenosos originalmente com vegetação florestal). Para tanto, realizou-se trabalho de campo com amostragens, em triplicata, de camadas superficiais do solo em 12 áreas representativas da baixa e alta Nhecolândia; procedeu-se determinações analíticas de 26 atributos do solo, totalizando 936 variáveis resposta e; análises estatísticas foram realizadas visando a síntese dos dados e apresentação dos resultados. Em ambas as paisagens predomina a fração areia fina na granulometria do solo. A classe textural dos solos variou de muito arenosa, arenosa média e média arenosa para as baías; muito arenosa para as cordilheiras, com Dp relacionada a presença do quartzo; e muito arenosa, arenosa média, média argilosa e argilosa para as salinas. Com relação aos atributos químicos e matéria orgânica, as baías se destacam pela maior acidez potencial (H+Al), teores de MO ligeiramente elevados e disponibilidade de íons metálicos, sobretudo Fe; nas cordilheiras, maiores médias de P-rem são mais evidentes; já os solos de salinas se relacionam a valores de pH mais alcalinos, elevada saturação por bases e altos índices de saturação por Sódio (ISNa). Paisagens de salinas apresentaram a maior variabilidade de dados e possuem atributos do solo que remetem a ação de diferentes processos ambientais.Universidade Federal de Uberlândia2023-03-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/6756010.14393/SN-v35-2023-67560Sociedade & Natureza; Vol. 35 No. 1 (2023): Sociedade & Natureza; v. 35 n. 1 (2023): 1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/67560/35690https://seer.ufu.br/index.php/sociedadenatureza/article/view/67560/35691Copyright (c) 2022 Diogo Costa Nascimento, Guilherme Resende Corrêa, Frederico Santos Gradella, Prímula Viana Campos, Viviane Arantes Koch, Bruno Nery Fernandes Vasconceloshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta Nascimento, Diogo Corrêa, Guilherme ResendeGradella, Frederico SantosCampos, Prímula VianaKoch, Viviane ArantesVasconcelos, Bruno Nery Fernandes2023-08-25T14:35:59Zoai:ojs.www.seer.ufu.br:article/67560Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2023-08-25T14:35:59Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
