Resumo: | In Mato Grosso do Sul, Brazil, there are limestone mines formed from sedimentary rocks, which have higher initial reactivity than that of metamorphic rock limestones. At Embrapa-Centro de Pesquisa Agropecuária do Oeste (CPAO), Dourados, Mato Grosso do Sul State, Brazil, the relative efficiency of limestone granularity fractions were evaluated under greenhouse conditions, using Dark-Red Latosol and Dusky-Red Latosol soils, both Oxisols. Each soil was amended with a dosage of lime high enough to elevate the pH (CaCl2) to 6.0. The treatments, at a completely randomized experimental design, were a control (without lime) and four granularity fractions: 4.00 to 2.00 mm; 2.00 to 0.84 mm; 0.84 to 0.30 mm; and 0.30 to 0.21 mm. Three limes were tested: calcitic of sedimentary origin (CS) and calcitic (CM) and dolomitic (DM) of metamorphic origin. No differences were observed on the effectiveness of the limes of the same origin in increasing the soil pH level. The relative efficiency of the different limes was influenced by the geologic origin, the granularity, the soil type, and the incubation period. The initial CS relative efficiency was higher than the ones from metamorphic origin, and was higher or at least equal up to three months of incubation. |

Na Embrapa-Centro de Pesquisa Agropecuária do Oeste (CPAO), em Dourados, MS, avaliou-se, em casa de vegetação, a eficiência relativa de frações granulométricas de calcários, em Latossolo Vermelho-Escuro álico franco-areno-argiloso e Latossolo Roxo distrófico muito argiloso. Em cada solo, aplicou-se dose de calcário estimada para elevar o pH em CaCl2 para 6,0. Os tratamentos, dispostos em delineamento inteiramente ao acaso, consistiram de: testemunha sem calcário e a aplicação de quatro frações granulométricas (malhas de 4,00 a 2,00; 2,00 a 0,84; 0,84 a 0,30 e 0,30 a 0,21mm) de três calcários: calcítico de origem sedimentar (CS) e calcítico (CM) e dolomítico (DM) de origem metamórfica. Não se verificaram diferenças na efetividade dos calcários calcítico e dolomítico, de mesma natureza geológica, em elevar o pH do solo. A eficiência relativa dos corretivos foi influenciada pela sua natureza geológica, granulometria, tipo de solo e tempo de incubação. A eficiência relativa inicial do CS foi superior às fontes metamórficas, e se manteve igual ou superior após três meses de incubação.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraKurihara, Carlos HissaoMaeda, ShizuoHernani, Luís CarlosSilva, William Marra1999-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5358Pesquisa Agropecuaria Brasileira; v.34, n.8, ago. 1999; 1443-1449Pesquisa Agropecuária Brasileira; v.34, n.8, ago. 1999; 1443-14491678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5358/2550info:eu-repo/semantics/openAccess2010-07-14T18:22:09Zoai:ojs.seer.sct.embrapa.br:article/5358Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-14T18:22:09Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
