Resumo: | Acid reactions and low available phosphorus in tropical soils limit forage yield. The aim was to evaluate soil chemical characteristics pH, P and Mg, forage nutritive values, critical soil and plant P levels and the residual effect of each source. The experiment was in a greenhouse with a Rhodic Haplustox, loam texture. Experimental design was a 5 x 4 factorial with five replicates which phosphate fertilizers were triple superphosphate, reactive rock phosphates Gafsa and Arad, and fused magnesium phosphate powder and coarse, applied at rates of 30, 60, 90 and 120 mg kg-1 P and a control treatment without P. The effectiveness of rock phosphates increased due to their residual effect. The coarse fused magnesium phosphate resulted in the lowest efficiency. The P critical level in soil and plant were 18 mg kg-1 and 2.4 g kg-1, respectively. The increase of phosphorus rates provided an increase in crude protein content. |

O objetivo foi avaliar as características químicas do solo pH, P e Mg, valores nutritivos das forragens, níveis críticos de P no solo e nas plantas e o efeito residual de cada fonte. O experimento foi realizado em casa de vegetação com Latossolo vermelho distrófico, textura média. O delineamento experimental foi inteiramente casualisado em fatorial 5 x 4, com cinco repetições cujos adubos fosfatados eram superfosfato triplo, fosfatos de rocha reativa Gafsa e Arad e fosfato de magnésio em pó e grosso, aplicados nas doses de 30, 60, 90 e 120 mg kg-1 de P e um tratamento controle sem P. A eficácia dos fosfatos rochosos aumentou devido ao seu efeito residual. O fosfato de magnésio fundido grosso resultou na menor eficiência. O nível crítico de P no solo e na planta foi de 18 mg kg-1 e 2,4 g kg-1, respectivamente. O aumento das taxas de fósforo proporcionou um aumento no teor de proteína bruta.EDUFU2020-04-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4262610.14393/BJ-v36n3a2020-42626Bioscience Journal ; Vol. 36 No. 3 (2020): May/June; 968-975Bioscience Journal ; v. 36 n. 3 (2020): Maio/Junho; 968-9751981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/42626/28648Brazil; ContemporaryCopyright (c) 2020 Henrique Coutinho Junqueira Franco, Bernardo Melo Montes Nogueira Borges, Sergio Gustavo Quassi de Castro, Michele Xavier Vieira Megda, Marcio Mahmoud Megda, Alan L.
