Resumo: The removal of native forest as well as of the surface soil horizons causes a significant decrease of microbial biomass and soil fertility. A slow and continuous recovery of the amount and of the quality of organic matter occurs in these areas, with reforestation. The objective of this work was to evaluate the fertility, organic matter and microbial biomass dynamics in areas reforested at different ages. The reforested clearings were set up in 2003, 2002, 2001, 1999 and 1993, with native regional species. The soil fertility was associated to soil organic matter content. The reforestation increased significantly the organic matter and the microbial biomass after the fourth year, and this indicates the need of an initial soil supply of carbon content, which can be provided by grasses or legumes used for forage.

Com o reflorestamento dessas áreas ocorre uma recuperação lenta e contínua da quantidade e qualidade da matéria orgânica. O objetivo deste trabalho foi avaliar a fertilidade do solo e a dinâmica da matéria orgânica e da biomassa microbiana no reflorestamento de clareiras com diferentes idades. Os reflorestamentos das clareiras foram realizados em 2003, 2002, 2001, 1999 e 1993, com espécies nativas da região. A fertilidade do solo nas condições edafoclimáticas locais está associada ao conteúdo de matéria orgânica no solo. O reflorestamento aumenta o teor de matéria orgânica e a biomassa microbiana a partir do quarto ano, indicando a necessidade de um aporte inicial do conteúdo de carbono no solo, que poderá ser suprido com a utilização de gramíneas ou leguminosas forrageiras.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMoreira, AdônisCosta, Danielle Gonçalves2004-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6869Pesquisa Agropecuaria Brasileira; v.39, n.10, out. 2004; 1013-1019Pesquisa Agropecuária Brasileira; v.39, n.10, out. 2004; 1013-10191678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6869/3925info:eu-repo/semantics/openAccess2014-08-29T17:07:46Zoai:ojs.seer.sct.embrapa.br:article/6869Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-29T17:07:46Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
