Resumo: Methods used to estimate the soil microbial activity are important to environmental monitoring of degraded areas. The objective of this research was to investigate the microbial activity of a semiarid soil cultivated with Atriplex nummularia Lindl. in a field receiving saline waste during one and three years, in comparison with an area without crop and irrigation. Soil cultivated during three years presented, during the dry season, values of pH, CE, and activity of FDA hydrolyses higher than those registered in other areas. However, a negative correlation between the microbial carbon and values of qCO2 was observed. The microbial biomass and the alkaline phosphates were also higher in the three years cultivated soil, in comparison with the native soil, non irrigated, confirming the role of halophytes for enhancing quality of soils under saline stress. Thus, the cultivation of A. nummularia is an alternative for using saline waste from the desalinization process.

O objetivo deste trabalho foi investigar a atividade microbiana de solo do semi-árido cultivado com Atriplex nummularia Lindl. em áreas que receberam rejeito salino durante um e três anos, em comparação com um solo nativo, sem cultivo e não irrigada. O solo cultivado por três anos e que recebeu rejeito salino apresentou, no período seco, valores de pH, CE e atividade de hidrólise do diacetato de fluoresceína (FDA) superiores aos das demais áreas. No entanto, foi observada correlação negativa entre o carbono microbiano e os valores do quociente metabólico (qCO2). A biomassa microbiana e a fosfatase alcalina também foram superiores no solo cultivado por três anos e que recebeu rejeito salino em relação ao solo nativo sem irrigação, confirmando o desempenho de plantas halófitas na melhoria da qualidade do solo sob condições de estresse salino. O cultivo de A. nummularia constitui uma das alternativas para utilização de rejeito salino proveniente da dessalinização por osmose reversa.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPereira, Sônia ValériaMartinez, Cosme RafaelPorto, Everaldo RochaOliveira, Beatriz Regina BritoMaia, Leonor Costa2004-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6835Pesquisa Agropecuaria Brasileira; v.39, n.8, ago. 2004; 757-762Pesquisa Agropecuária Brasileira; v.39, n.8, ago. 2004; 757-7621678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6835/3891info:eu-repo/semantics/openAccess2014-08-21T19:05:36Zoai:ojs.seer.sct.embrapa.br:article/6835Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-21T19:05:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
