Resumo: This work was carried out on degraded area by oil shale mining, to evaluate the effect of different fertilizations and revegetations with forage species on the total dry production and the macronutrients concentration and extraction by plants. The experiment was conducted for 12 months at São Mateus do Sul, Paraná State, Brazil, in a randomized block with split plots design, being three plots related to fertilization and three subplots related to forage species. The fertilizations used were: I - mineral fertilizer with aerial part left over; II - mineral and organic fertilizer with aerial part removed; III - mineral fertilizer with aerial part removed. Forage composed the following systems: Systems I and II - perennial grasses and legumes species of summer and winter; System III - annual grasses and legumes species of summer and winter. The evaluations were related to dry matter and concentration and extraction by plant of P, K, Ca, Mg, C and N. It was observed greatest dry matter production in the treatment with organic fertilization and with annual forages, and that the extraction of nutrients by plants was, in general, superior in treatments with high dry matter production.

O experimento foi conduzido durante 12 meses, no município de São Mateus do Sul, PR, e o delineamento foi de blocos ao acaso, com parcelas subdivididas, envolvendo três parcelas referentes às adubações, e três subparcelas com as forrageiras, totalizando 36 unidades experimentais. As adubações utilizadas foram: I - adubação mineral com permanência da parte aérea; II - adubação mineral e orgânica com exportação da parte aérea; III - adubação mineral com exportação da parte aérea. As forrageiras constituíram diferentes sistemas, da seguinte forma: Sistemas I e II - gramíneas e leguminosas perenes de inverno e verão; Sistema III - gramíneas e leguminosas anuais de inverno e verão. As avaliações realizadas foram quanto ao peso de matéria seca e à concentração e extração pela planta de P, K, Ca, Mg, C e N. Conclui-se, no que se refere ao período de estudo, que as maiores produções de matéria seca ocorreram na adubação orgânica e nas forrageiras anuais, e que a extração dos nutrientes pela planta, de maneira geral, foi superior nos tratamentos com maior produção de matéria seca.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFavaretto, NerildeMoraes, Aníbal deMotta, Antônio Carlos VargaPrevedello, Beatriz Monte Serrat2000-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5756Pesquisa Agropecuaria Brasileira; v.35, n.2, fev. 2000; 299-306Pesquisa Agropecuária Brasileira; v.35, n.2, fev. 2000; 299-3061678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5756/2860info:eu-repo/semantics/openAccess2010-07-30T18:14:16Zoai:ojs.seer.sct.embrapa.br:article/5756Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-30T18:14:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
