Resumo: | This study aimed to evaluate the dynamics of the physical and chemical recovery of the substrates of waste dumps of different ages undergoing natural regeneration, in a calcary mining in Salto de Pirapora - SP, Brazil. Characterization of the vegetation, vegetation and physical and chemical cover of the substrates of the abandoned waste dumps since 1994 and 2013 and the soil of a native forest fragment adjacent to the mining was carried out. Twelve plots of 10x10m were allocated in each environment. It was verified that the soil cover rate with herbaceous, grassy, regenerating and litter of the sterile stacks are similar to the native forest fragment. The same was observed for the physical characterization of soil resistance to penetration, soil moisture content and relative light index. For the chemical characteristics, in all areas sampled there is aluminum deficiency which, consequently, presented low potential acidity and alkaline pH. The CEC of the substrates of the waste dumps presented values similar to the CEC of the native forest fragment, with abundance in some essential nutrients, indicating the possibility of vegetation development in the sterile stacks and the contribution of the natural regeneration to the substrates. Thus, the plant-soil relationship via natural regeneration in the sterile piles contributed to the improvement of the edaphic quality of the substrates over time, being a potential form of recovery in calcary mining. Thereby, the Fabaceae predominated on the waste dumps, especially Leucaena leucocephala, which, despite being an exotic species, is relevant for the current recovery stage of the substrates. |

Foram realizados a caracterização da vegetação, cobertura vegetal e a física e química dos substratos das pilhas de estéril abandonadas desde 1994 e 2013 e do solo de um fragmento florestal nativo adjacente à cava de mineração. Foram alocadas 12 parcelas de 10x10m em cada ambiente. Verificou-se que o índice de cobertura do solo com herbáceas, gramíneas, regenerantes e serapilheira das pilhas de estéril estão se assemelhando aos valores encontrados no fragmento florestal nativo. O mesmo foi observado para a caracterização física quanto à resistência mecânica a penetração do solo, teor de umidade do solo e ao índice relativo de luz. Para as características químicas do substrato, em todas as áreas amostradas há deficiência em teores alumínio que, consequentemente, apresentaram baixa acidez potencial e pH alcalino. A CEC dos substratos das pilhas de estéril apresentou valores semelhantes à CEC do fragmento florestal nativo, com abundancia em alguns nutrientes essenciais, apontando a possibilidade de desenvolvimento da vegetação nas pilhas de estéril e a contribuição da regeneração natural para os substratos. Assim, a relação planta-solo via regeneração natural nas pilhas de estéril contribuiu para a melhoria da qualidade edáfica dos substratos ao longo do tempo. A relação planta-solo via regeneração natural nas pilhas de estéril contribuiu para a melhoria da qualidade edáfica dos substratos ao longo do tempo, sendo essa uma forma potencial de recuperação em mineração de calcário. Houve o predomínio da família Fabaceae nas pilhas de estéril, com o destaque para a Leucaena leucocephala, que a pesar de ser uma espécie exótica, apresenta-se de maneira relevante para o estágio atual da recuperação dos substratos.CERNECERNE2018-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://cerne.ufla.br/site/index.php/CERNE/article/view/1780CERNE; Vol. 24 No. 1 (2018); 18-26CERNE; v. 24 n. 1 (2018); 18-262317-63420104-7760reponame:Cerne (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAenghttps://cerne.ufla.br/site/index.php/CERNE/article/view/1780/1059Copyright (c) 2018 CERNEinfo:eu-repo/semantics/openAccessLima, Marcelle TeodoroRibeiro, Admilson ÍrioDias, Herly Carlos TeixeiraRosa, Alexandra GuidelliPires, Gustavo TrevizanTonello, Kelly Cristina2018-07-24T14:22:58Zoai:cerne.ufla.br:article/1780Revistahttps://cerne.ufla.br/site/index.php/CERNEPUBhttps://cerne.ufla.br/site/index.php/CERNE/oaicerne@dcf.ufla.br||cerne@dcf.ufla.br2317-63420104-7760opendoar:2024-05-21T19:54:35.108286Cerne (Online) - Universidade Federal de Lavras (UFLA)true |
