Resumo: The current high price of potassium chloride and the dependence of Brazil on imported materials to supply the domestic demand call for studies evaluating the efficiency of alternative sources of nutrients. The aim of this work was to evaluate the effect of silicate rock powder and a manganese mining by-product, and secondary materials originated from these two materials, on soil chemical properties and on brachiaria production. This greenhouse experiment was conducted in pots with 5 kg of soil (Latossolo Vermelho-Amarelo distrófico - Oxisol). The alternative nutrient sources were: verdete, verdete treated with NH4OH, phonolite, ultramafic rock, mining waste and the proportion of 75 % of these K fertilizers and 25 % lime. Mixtures containing 25 % of lime were heated at 800 ºC for 1 h. These sources were applied at rates of 0, 150, 300, 450 and 600 kg ha-1 K2O, and incubated for 45 days. The mixtures of heated silicate rocks with lime promoted higher increases in soil pH in decreasing order: ultramafic rock>verdete>phonolite>mining waste. Applying the mining waste-lime mixture increased soil exchangeable K, and available P when ultramafic rock was incorporated. When ultramafic rock was applied, the release of Ca2+ increased significantly. Mining subproduct released the highest amount of Zn2+ and Mn2+ to the soil. The application of alternative sources of K, with variable chemical composition, altered the nutrient availability and soil chemical properties, improving mainly plant development and K plant uptake, and are important nutrient sources.

O objetivo deste trabalho foi avaliar o efeito de rochas silicáticas e de um subproduto de mineração de manganês e suas alterações nos atributos químicos do solo e na produção da braquiária. O experimento foi realizado em casa de vegetação, em vasos com 5 kg de um Latossolo Vermelho-Amarelo distrófico. As fontes alternativas de nutrientes foram: verdete, verdete calcinado e tratado com NH4OH, fonolito, ultramáfica, rejeito e a proporção de 75 % dessas fontes com 25 % de calcário calcítico. As misturas que apresentaram 25 % de calcário foram calcinadas a 800 ºC por 1 h. As fontes foram aplicadas nas doses de 0; 150; 300; 450; e 600 kg ha-1 de K2O e permaneceram incubadas por um período de 45 dias. As misturas de rochas silicáticas calcinadas com calcário que promoveram maior aumento nos valores de pH do solo foram: ultramáfica, verdete, fonolito e rejeito. Com a aplicação da mistura de rejeito, elevaram-se o K+ do solo e o P disponível, quando da incorporação da ultramáfica, Quando foi aplicada ultramáfica, o teor de Ca2+ no solo aumentou significantemente. O rejeito liberou a maior quantidade de Zn2+ e Mn2+ para o solo. As fontes alternativas de K com composição química variada, quando misturadas ao solo, alteraram a disponibilidade de nutrientes e os atributos químicos do solo, melhorando principalmente o desenvolvimento e a absorção de K pelas plantas, sendo importantes fontes de nutrientes para o solo.Sociedade Brasileira de Ciência do Solo2017-11-29T12:43:38Z2017-11-29T12:43:38Z2015info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMARTINS, V. et al.
