Resumo: The low agronomic efficiency of the Brazilian rock phosphates and the high industrial cost of soluble phosphates production, because of sulphur importation, request search for simplified utilization process of these raw materials. The possibility to increase the residual effect of phosphorus sources added before or after the urban waste composting by dry matter production and phosphorus absorption of forage sorghum (Sorghurn bicolor) was studied. A greenhouse experiment was conducted with a clayey Red-Yellow Latosel at three pH levels. The experimental design used was a factorial in randomized blocks. After culture of beans, the sorghum was sowed in the same pots as beans (Phaseolus vulgaris L.) and harvested 90 days after planting. The addition of rock phosphate of the urban waste before or after composting did not increase the availability of the residual phosphorus to sorghum, at any of pH levels studied. However, there was an increase of the residual phosphorus availability when the superphosphate was added before or after the urban waste composting, as well as at pH 4.8. This result shows the potential of organic waste management with more soluble phosphorus sources on acid soils.

Estudou-se a possibilidade de alimento do efeito residual das fontes de fósforo adicionadas ao lixo urbano antes ou após a sua compostagem, pela produção de matéria seca e absorção de fósforo em sorgo forrageiro (Sorghum bicolor). Foi feito um experimento em casa de vegetação com Latossolo Vermelho-Amarelo argiloso, em três níveis de pH. O esquema experimental usado foi um fatorial em blocos ao acaso. Após um cultivo de feijoeiro, semeou-se o sorgo nos mesmos vasos, tendo a colheita sido realizada 90 dias após o plantio. A adição de fosfatos naturais ao lixo antes ou após a soa compostagem não aumentou a disponibilidade do fósforo residual para o sorgo em nenhum dos três níveis de pH estudados. Houve aumento da disponibilidade do fósforo residual quando o superfosfato triplo foi adicionado ao lixo antes ou após a sua compostagem, inclusive em pH 4,8. Este resultado mostra o potencial do manejo de adubo orgânico com fontes de fósforo mais solúveis em solos ácidos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPeixoto, Ricardo Trippia dos G.Almeida, Dejair Lopes deFranco, Avilio Antonio2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15830Pesquisa Agropecuaria Brasileira; v.24, n.5, maio 1989; 587-592Pesquisa Agropecuária Brasileira; v.24, n.5, maio 1989; 587-5921678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15830/9901info:eu-repo/semantics/openAccess2014-08-26T18:35:54Zoai:ojs.seer.sct.embrapa.br:article/15830Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-26T18:35:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
