Resumo: | Arbuscular mycorrhizal fungi (AMF) present a great biotechnological potential, but to be successfully applied, it is necessary to know how these organisms react to agricultural practices. This research aimed to verify the effects of two management systems, conventional and organic, applied to citrus orchards and nurseries, on AMF communities, compared to soil from a native forest. A total of 36 soil samples were collected, and their chemical characteristics and AMF species occurrence were evaluated. Management systems did not change AMF communities, even with the soil chemical alterations due to organic fertilizers amendment, which increased pH, organic matter, calcium and magnesium values. However, communities were affected by the time of implementation and regions where orchards and the nurseries were located. These differences are probably due to the stability of older orchards and the evolutionary characteristics of each local. |

O objetivo deste trabalho foi avaliar o efeito de duas formas de manejo, convencional e orgânica, em pomares e viveiros de citros, nas comunidades de FMA, comparadas com solo de mata nativa. Um total de 36 amostras de solo foram coletadas, e suas características químicas e a ocorrência de espécies de FMA foram avaliadas. Os sistemas de manejo não alteraram as comunidades de FMA, apesar das modificações químicas no solo causadas pelas aplicações de fertilizantes orgânicos, que elevaram os valores de pH, matéria orgânica, Ca e magnésio. No entanto, as comunidades foram afetadas pelo tempo de implantação e pelas regiões onde se localizam os pomares e viveiros. Estas diferenças se devem provavelmente à estabilidade dos pomares mais antigos e às características evolutivas de cada local.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFocchi, Sandro SouzaDal Soglio, Fábio KesslerCarrenho, Rosilainede Souza, Paulo Vitor DutraLovato, Paulo Emílio2004-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6795Pesquisa Agropecuaria Brasileira; v.39, n.5, maio 2004; 469-476Pesquisa Agropecuária Brasileira; v.39, n.5, maio 2004; 469-4761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6795/3851info:eu-repo/semantics/openAccess2014-07-18T17:15:38Zoai:ojs.seer.sct.embrapa.br:article/6795Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-18T17:15:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
