Resumo: | In laboratory, increasing volumes of stillage (equivalents to 50, 100, 150, 200 and 400 m3 /ha), with and without addition of N and P, were incubated with a Typic Paleudult soil, and the effects on exchangeable cations and other nutrients in the soil were studied. Total N and C levels were not affected. Exchangeable K, Ca and Mg levels increased with the increasing levels of stillage applied. However, in each treatment, Ca and Mg increases were higher than the amounts of these elements introduced in the soil by the dose of stillage. The levels of exchangeable Na were not affected with the increasing levels of applied stillage. The soil pH increased while the levels of exchangeable Al, available P and nitrate decreased. The point of zero charge (p.z.c.) determined for the soil treated with 400 m3/ha of stillage, with and without addition of N and P, did not differ from the value of the untreated soil. The addition of N and P to the stillage did not affect the general trends observed for the soil treated with stillage. However, the levels of ammonium, which were constant for the different treatments with stillage without N and P, tended to decrease during incubation for the treatment with stillage plus N and P. |

Os teores de N-total, C e C/N praticamente não se alteraram, em ambos os tratamentos, após a aplicação das doses de vinhaça. Um aumento nos teores de K, Ca e Mg trocáveis acompanhou, em ambos os tratamentos, os níveis crescentes de vinhaça incorporada às amostras de solo. Entretanto, os teores de Ca e Mg trocáveis, em todos os tratamentos, foram superiores aos introduzidos pelas crescentes doses de vinhaça. Por outro lado, os teores de Na trocável mantiveram-se praticamente constantes em ambos os tratamentos. Aumento moderado do pH e decréscimo nos teores de alumínio trocável, de fósforo assimilável, e de nitrato, acompanharam a aplicação de doses crescentes de vinhaça às amostras de solo, em ambos os tratamentos. Os teores de amônio, que, nos tratamentos com vinhaça, sem adição de N e P, se mantiveram constantes, tenderam a decrescer nos tratamentos que receberam N e P. em relação àqueles adicionados no início da incubação, para ambos os tratamentos. Não houve diferença entre os valores do PCZ, determinados nos tratamentos que receberam a maior dose de vinhaça (400 m 3 /ha), com e sem N e P, como também destes para o PCZ determinado no solo original.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNunes, Marcos R.Velloso, Ary Carlos X.Leal, Jair R.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16768Pesquisa Agropecuaria Brasileira; v.16, n.2, fev. 1981; 171-176Pesquisa Agropecuária Brasileira; v.16, n.2, fev. 1981; 171-1761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16768/11090info:eu-repo/semantics/openAccess2014-04-15T19:39:03Zoai:ojs.seer.sct.embrapa.br:article/16768Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:39:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
