Resumo: The objective of this work was to evaluate the efficiency and the residual effects of both molten and ground alkaline potassium-silicate rocks (K1) and of ground phonolite rock (K2), as sources of potassium, compared with the traditional source (KCl), in grain crop successions. Two experiments – one with the succession soybean-wheat-corn and the other with the succession corn-millet-soybean – were conducted on a Typic Haplorthox in a randomized complete block design with four replicates. The treatments consisted of three sources (KCl, K1, and K2) and four rates of K (corresponding to 0, 0.5, 1.0, and 2.0 times the recommended rates for soybean and corn). The used sources did not affect leaf K concentration in soybean, but KCl and K2 similarly increased leaf K concentration in corn. Regardless of the source, K application increased the yield of all crops. The K1 and K2 sources present agronomic efficiencies equivalent to that of KCl. K1 and K2 show a more pronounced residual effect than KCl, especially on crops grown approximately one year after their application and under K rates above those recommended for the crops.

Dois experimentos – um com sucessão soja-trigo-milho e outro com sucessão milho-milheto-soja – foram conduzidos em Latossolo Vermelho argiloso, em delineamento de blocos ao acaso, com quatro repetições. Os tratamentos consistiram de três fontes (KCl, K1 e K2) e quatro doses de K (correspondentes a 0, 0,5, 1,0 e 2,0 vezes a dose recomendada para a cultura da soja e do milho). As fontes não afetaram a concentração de K nas folhas da soja, mas KCl e K2 aumentaram de forma semelhante a concentração de K nas folhas do milho. Independentemente da fonte, a aplicação de K aumentou as produtividades de todas as culturas. As fontes alternativas K1 e K2 apresentam eficiências agronômicas equivalentes à do KCl. K1 e K2 têm efeitos residuais mais pronunciados que o do KCl, especialmente em cultivos realizados aproximadamente um ano após suas aplicações e com doses de K acima das recomendadas para as culturas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e TecnológicoConselho Nacional de Desenvolvimento Científico e TecnológicoSoratto, Rogério PeresCrusciol, Carlos Alexandre CostaCampos, Murilo deGilabel, Amanda PradoCosta, Claudio Hideo Martins daCastro, Gustavo Spadotti AmaralFerrari Neto, Jayme2022-05-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27069Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02686Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e026861678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27069/14979Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/27069Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
