Resumo: A study was made, under greenhouse conditions, on the effects of liming and  phosphorus fertilizer (300 kg P205/ha) aplication on dry matter accumulation and P-uptake by sorghum plants. Plants were grown in four Oxisols originally under cerrado vegetation. Liming per se, had no effects on dry matter accumulation and P-uptake. Likewise, phosphorus application without liming did not result in any increase in dry matter accumulation and P-uptake, except for one Oxisol where Al-saturation level was originally low. There was a positive correlation between P-fertilization and liming on dry matter accumulation and P-uptake by plants. The results showed that the main effect of liming in these soils was on the elimination of phytotoxicity, mainly due to exchangeable aluminum.

Não se observou qualquer influência da calagem per se sobre a acumulação de matéria seca ou absorção de fósforo pela planta estudada. De forma idêntica, a aplicação de fósforo, sem calagem, não resultou em aumento de matéria seca, ou absorção de fósforo por sorgo, em relação à testemunha, exceto em um dos latossolos, cuja saturação com Al era originariamente baixa. Observou-se expressivo efeito da interação calagem x adubação fosfatada sobre a produção de massa vegetal e na absorção de P pelas plantas. Os resultados mostram que a calagem atuou nesses solos reduzindo a toxidez principalmente do Al trocável, sem que, necessariamente, tenha havido influência da correção de acidez na disponibilidade de P no solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSouza, Luiz Francisco S.Fernandes, Manlio S.Velloso, Ary Carlos X.Castro, Abeilard F. de2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15348Pesquisa Agropecuaria Brasileira; v.18, n.7, jul. 1983; 715-720Pesquisa Agropecuária Brasileira; v.18, n.7, jul. 1983; 715-7201678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15348/9214info:eu-repo/semantics/openAccess2014-04-16T18:59:42Zoai:ojs.seer.sct.embrapa.br:article/15348Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:59:42Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
