Resumo: This eight year study was started in 1960 to determine the influence of sources and rates of phosphorus application on the production of rice. The experiment was conducted on a planosol located in Rio Grande do Sul at the Instituto de Pesquisas e Experimentação Agropecuárias do Sul. Four sources of phosphorus were applied to the soil at the rate of 90 kg/ha of P2O5. Periodically the various fractions of phosphorus were determined. From the data obtained in the laboratory and the production of rice the following suggested studies are made: 1. Transformations that occur in the soil with added phosphorus. 2. Comparison between the forms of phosphorus in the soil and their availability. 3. Relation between the availability of phosphorus and the production of rice.

Esse experimento foi instalado em 1960 pela Seção de Solos do Instituto de Pesquisas e Experimentação Agropecuárias do Sul (IPEAS), sobre um Planossolo. O objetivo inicial era o estudo de fontes e doses de fósforo e sua influência na produção do arroz. A análise de fracionamento do fósforo no solo e a determinação do fósforo disponível foram executadas em parcelas adubadas por 8 anos consecutivos, com doses de 90 kg/ha de P2O5 de quatro diferentes fontes. Os dados obtidos no laboratório e as produções da cultura do arroz permitiram os seguintes estados: a) transformações que ocorrem no solo com o fósforo adicionado; b) comparação entre as formas de fósforo no solo e sua disponibilidade; c) relação entre a disponibilidade de fósforo e a produção de arroz.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGoedert, Wenceslau J.Patella, José FranciscoMoraes, José Francisco V.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17613Pesquisa Agropecuaria Brasileira; v.6, n.1, 1971: Série Agronomia e Veterinária; 39-43Pesquisa Agropecuária Brasileira; v.6, n.1, 1971: Série Agronomia e Veterinária; 39-431678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17613/11822info:eu-repo/semantics/openAccess2014-04-15T18:35:58Zoai:ojs.seer.sct.embrapa.br:article/17613Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:35:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
