Resumo: The objective of this work was to investigate changes in soil chemical characteristics, phosphorous concentrations in maize leaves, and the agronomic efficiency (AE) of magnesium thermophosphates produced from rocks of the Maicuru complex in the Brazilian Amazon Basin, in comparison with triple superphosphate (TSP). The thermophosphates consisted of a mixture of raw material from apatite, dunite, and quartz sandstone from Maicuru, aiming to adjust the contents of P, Mg, and Si. The mixture was melted, ground, and subjected to the analysis of solubility, chemical characteristics, and granulometry. The experiment consisted of two rates of dolomitic lime (0 and 2.4 Mg ha-1), three rates of P (20, 60, and 100 mg kg-1 soil), and four sources of P (TSP and three Mg thermophosphates), as well as of two control treatments, with and without lime. Three replicates were carried out per treatment in pots containing plants of the BR 5107 maize hybrid. Phosphorous concentration was determined in maize leaves at 45 days after sowing. The Mg thermophosphates showed a high AE and a higher neutralizing effect with the application of lime, which improved soil chemical characteristics and AE. The thermophosphates obtained from rocks of the Maicuru complex can be an alternative P fertilizer in maize production.

Os termofosfatos consistiram de mistura de matéria-prima de apatita, dunita e arenito quartzoso de Maicuru, para ajuste dos conteúdos de P, Mg e Si. A mistura foi fundida, moída e submetida à análise de solubilidade, características químicas e granulometria. O experimento consistiu em dois níveis de calcário dolomítico (0 e 2,4 Mg ha-1), três níveis de P (20, 60 e 100 mg kg-1 de solo) e quatro fontes de P (TSP e três termofosfatos magnesianos), além de dois controles, com e sem calcário. Foram realizadas três repetições para cada tratamento, em vasos com plantas de milho do híbrido BR 5107. A concentração de P foi determinada nas folhas de milho aos 45 dias após a semeadura. Os termofosfatos magnesianos apresentaram alta EA e maior poder neutralizante com a aplicação de calcário, o que melhorou as características químicas do solo e a EA. Os termofosfatos obtidos de rochas do complexo Maicuru podem ser alternativa de fertilizante fosfatado na produção de milho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCastro, Cesar deCosta, Marcondes Lima daFirmano, Ruan FranciscoGuardani, RobertoSilva, George Rodrigues da2023-08-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27410Pesquisa Agropecuaria Brasileira; V.58, Jan./Dec., 2023: Publicação contínua em volume anual; e02892Pesquisa Agropecuária Brasileira; V.58, Jan./Dec., 2023: Publicação contínua em volume anual; e028921678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27410/15183Direitos autorais 2023 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2023-12-14T19:04:58Zoai:ojs.seer.sct.embrapa.br:article/27410Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2023-12-14T19:04:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
