Resumo: | Pig slurry is a fertilizer but its improper use can contaminate water and soil. The objectives of this study were to determine soil chemical attributes affected by liquid swine manure applied on native pasture and to evaluate the agronomic and environmental impacts of its use. An experiment with liquid swine manure application on native pasture was carried out from November 1995 to November 1999, in an area nearby a swine production place in Paraíso do Sul county, State of Rio Grande do Sul, Brazil, to evaluate the soil chemical attributes. The liquid swine manure application rates were: 0, 20 and 40 m3 ha-1, applied every 45 to 60 days. Right before each manure application, the forage was mowed and taken out. The liquid manure application on natural grass field every 45 to 60 days cause a high addition of soil chemical elements, specially P, Ca and Mg. The reduction of Al saturation may improve soil environment to plant growth, however, the K content should be monitored, because under grazing the latter could decrease. The system should have high N leaching in nitrate form, because, despite heavy N application through manure, the soil N content remains almost the same. This, in turn, could become an environmental problem, as long as one consider a high P content at surface also as potential water pollutant. |

O objetivo deste trabalho foi avaliar alterações em algumas características químicas de um solo sob pastagem natural com o uso de esterco líquido de suínos e suas implicações agronômicas e ambientais. O experimento foi conduzido de novembro de 1995 a novembro de 1999 em Paraíso do Sul, RS, em condomínio de suinocultores. Os tratamentos constituíram-se de 0, 20 e 40 m3 ha-1 de esterco líquido de suínos, aplicado em intervalos de 45 a 60 dias. Em cada época de aplicação de esterco, a pastagem natural era roçada, a forragem retirada e o esterco reaplicado. Os resultados mostraram que o uso sistemático de esterco líquido de suínos representa a adição de grandes quantidades de nutrientes ao solo, elevando principalmente os teores de P, Ca e Mg em áreas sob pastagem natural. O ambiente para o crescimento das plantas também pode ser melhorado com o uso de esterco líquido de suínos pela diminuição na saturação de Al, mas deve-se monitorar o teor de K no solo, porque, sob pastoreio, os teores podem decrescer. O fato de adicionar altas quantidades de N por meio do esterco líquido de suínos sem alterar seus teores no solo evidencia que ocorrem grandes perdas de N, principalmente na forma de nitrato. Além disso, a elevada concentração de P na camada mais superficial do solo mostra que estes elementos podem comprometer a qualidade do ambiente, especialmente como contaminantes da água.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCeretta, Carlos AlbertoDurigon, RegesBasso, Claudir JoséBarcellos, Luiz Antônio RochaVieira, Frederico Costa Beber2003-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6630Pesquisa Agropecuaria Brasileira; v.38, n.6, jun. 2003; 729-735Pesquisa Agropecuária Brasileira; v.38, n.6, jun. 2003; 729-7351678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6630/3687info:eu-repo/semantics/openAccess2010-08-18T18:13:16Zoai:ojs.seer.sct.embrapa.br:article/6630Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-18T18:13:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
