Resumo: The objective of this work was to evaluate corn (Zea mays) utilization of ammoniacal N from pig slurry (PS). A field experiment was carried out in a typic Hapludalf. The treatments consisted of the application or not of PS on oat straw, in no-tillage and reduced tillage planting systems. In order to quantify the destination of applied ammoniacal N from the PS, the ammoniacal fraction was enriched with (15NH4)2SO4. The utilization of ammoniacal N from pig slurry by corn crop was of 15.3% and did not differ between no-tillage and reduced tillage soil systems. At corn physiological maturity, the amount of 15N recovered from the soil, at 120-cm depth, and from the plant (grain+shoot+roots) was 49.6% of the 15N applied with pig slurry. The organic N fractions from pig slurry and from soil organic matter were the main sources of N for corn.

O experimento foi conduzido em Argissolo Vermelho distrófico arênico. Os tratamentos avaliados consistiram da aplicação ou não de DLS sobre resíduos culturais de aveia, em plantio direto e preparo reduzido do solo. Para quantificar o destino do N amoniacal aplicado, a fração amoniacal dos DLS foi enriquecida com (15NH4)2SO4. O aproveitamento do N amoniacal dos DLS pelo milho foi de apenas 15,3% e não diferiu com o uso do DLS em plantio direto ou em preparo reduzido do solo. Na maturação fisiológica do milho, a quantidade de 15N dos DLS recuperada no solo, até a profundidade de 120 cm, e na planta (parte aérea+grãos+raízes) correspondeu a 49,6% do 15N aplicado. A fração de N orgânico dos DLS e a matéria orgânica do solo foram as principais fontes de N para a cultura do milho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq, CAPESGiacomini, Sandro JoséAita, CelsoJantalia, Claudia PozziUrquiaga, Segundo2010-11-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/2055Pesquisa Agropecuaria Brasileira; v.44, n.7, jul. 2009; 761-768Pesquisa Agropecuária Brasileira; v.44, n.7, jul. 2009; 761-7681678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/2055/5760https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/2055/1438info:eu-repo/semantics/openAccess2012-06-17T11:50:46Zoai:ojs.seer.sct.embrapa.br:article/2055Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:50:46Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
