Summary: | The objective of this work was to evaluate the horizontal and vertical distribution of soil phosphorus and soybean yield in single‑crop and in integrated crop‑livestock‑forest (ICLF) systems. The evaluated treatments were: forest planted with eucalyptus; soybean crop and off-season corn intercropped with Urochloa brizantha 'Marandu'; U. brizantha pasture; ICLF system; and two control areas, with native forest and fallow. Soil samples were taken at the depths of 0–5, 5–10, 10–20, 20–30 cm for determining chemical characteristics. Evaluations were done in the second crop year after the implementation of the experiment. In the ICLF system, soil and yield were evaluated in four equidistant transects, at the center of the tree rows, and at 3, 6, 10, and 15 m from the rows on the northern and southern sides. Available P levels (Mehlich‑1) were greater at the upper soil layers, in the systems with soybean/off-season corn and ICLF. In ICLF, available P contents did not differ between the distances from the tree rows, and soybean yield did not differ from the one observed in the soybean/off-season corn system. Therefore, a two‑year ICLF is not yet capable of major interference on soil chemical characteristics and on soybean yield. |

Foram avaliados os tratamentos: floresta plantada de eucalipto; lavoura de soja e milho safrinha consorciado com Urochloa brizantha 'Marandu'; pastagem de U. brizantha; sistema de ILPF; e duas áreas controle, com floresta nativa e pousio. O solo foi coletado nas camadas de 0–5, 5–10, 10–20 e 20–30 cm, para determinação das características químicas. As avaliações foram realizadas no segundo ano agrícola após a implantação do experimento. No sistema de ILPF, solo e produtividade foram avaliados em quatro transectos equidistantes, no centro do renque e a 3, 6, 10 e 15 m do renque, nas faces norte e sul. Os teores de P disponível (Mehlich‑1) foram maiores nas camadas superficiais do solo, nos sistemas com soja/milho safrinha e com ILPF. No ILPF, os teores de P disponível não diferiram entre as distâncias do renque das árvores, e a produtividade de soja não diferiu da observada no sistema com soja/milho safrinha. Portanto, com dois anos de implantação, o sistema ILPF ainda não é capaz de interferir marcadamente nas características químicas do solo e na produtividade da soja.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e TecnológicoDiel, DeboraBehling, MaurelFarias Neto, Austeclinio Lopes deIsernhagen, Elaine Cristina Casula2014-08-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/19035Pesquisa Agropecuaria Brasileira; v.49, n.8, ago. 2014; 639-647Pesquisa Agropecuária Brasileira; v.49, n.8, ago. 2014; 639-6471678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/19035/12755https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/19035/11397info:eu-repo/semantics/openAccess2014-10-13T16:23:19Zoai:ojs.seer.sct.embrapa.br:article/19035Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-13T16:23:19Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
