Resumo: | The steel residues application (SR) in sandy soils, under a proper handling management, can result in a benefits range, among which, the soil acidity correction. This study investigated the gralunometric composition of three slags and one exhaustion powder from a steel mill, in the municipality of Marabá-PA, in addition to the ability of soil pH correction. To identify the granulometric fractions were used number 8, 10, 16 and 18 mesh sieves. The pH correction experiment were made in factorial scheme, evaluated 3 doses of each RS (1.5 t ha-1, 2.0 t ha-1 and 2.5 t ha-1) in vases with Neosol, for 60 days. Residues from the steel refining (EAFS, LDS and EAFD) showed a particle size predominantly under 1.00 mm, and promoted pH values above to 7.0. The blast furnace slag obtained domain of particle sizes > 2.00 mm, with 77% of the material retained in the sieves, and their soil disposition promoted similar results to dolomitic limestone, used traditionally to pH correction in acid soils, representing an alternative in soil preparation. Others residues also showed the soil pH correction capacity, although the used dosages proved to be above the ideal, with values above 7 and alkalinity tendency. The necessity of an investigation of EAFS, LDS and EAFD residues dosage are essential to pH soil correction, in order to condition the soil to pH ranges considered ideals (6-6.5). |

Este estudio investigó la composición granulométrica de tres escorias y un polvo de escape generado en una planta siderúrgica del municipio de Marabá-PA, además de la capacidad de corregir el pH en el suelo. Se utilizaron tamices de malla número 8, 10, 16 y 18 (ABNT) para determinar las fracciones de tamaño de partícula. El experimento de corrección de pH realizado en un esquema factorial, evaluó 3 dosis de cada RS (1,5 t.ha-1, 2,0 t.ha-1 y 2.5 t.ha-1) en floreros con neossol, durante 60 días. Los residuos del refino de acero (EAFS, LDS y EAFD) presentaron un tamaño de partícula predominante por debajo de 1,00 mm y promovieron valores de pH superiores a 7,0. La escoria de alto horno tuvo un tamaño de dominio> 2,00 mm, con 77% del material retenido en los tamices, y su disposición en el suelo promovió resultados similares a la caliza dolomítica tradicionalmente utilizada para la corrección de pH en suelos ácidos, lo que puede representar una alternativa en preparación del suelo. Los demás residuos también mostraron capacidad para corregir el suelo, aunque las dosis empleadas resultaron ser superiores al ideal, con valores superiores a > 7 y tendencia a la alcalinidad. La necesidad de una investigación de la dosificación en residuos de EAFS, LDS y EAFD es fundamental para corregir el pH del suelo, con el fin de acondicionar el suelo a rangos considerados ideales para pH (6-6,5).A aplicação de resíduos siderúrgicos (RS) em solos arenosos, sob uma gestão de manejo adequada, pode resultar em uma gama de benefícios, dentre os quais, a correção da acidez do solo. Este estudo investigou a composição granulométrica de três escórias e um pó de exaustão gerados em uma usina siderúrgica no município de Marabá-PA, além da capacidade de correção do pH em solo. Foram utilizadas peneiras de malhas nº 8, 10, 16 e 18 (ABNT) para determinar as frações granulométricas. O experimento de correção de pH realizado em esquema fatorial, avaliou 3 doses de cada RS (1,5 t.ha-1, 2,0 t.ha-1 e 2,5 t.ha-1) em vasos com neossolo, por 60 dias. Os resíduos provenientes do refino do aço (EAFS, LDS e EAFD) apresentaram granulometria predominante inferior a 1,00 mm, e promoveram valores de pH superiores a 7,0. A escória de alto forno obteve dominio a granulometrías > 2,00 mm, com 77% do material retido nas peneiras, e sua disposição no solo promoveu resultados similares ao calcáreo dolomítico tradicionalmente utilizado para a correção de pH em solos ácidos, podendo representar uma alternativa no preparo do solo. Os demais resíduos também apresentaram capacidade de correção do solo, embora as doses utilizadas demonstraram ser acima do ideal, com valores acima de > 7 e tendência a alcalinidade. A necessidade de uma investigação da dosagem nos resíduos EAFS, LDS e EAFD são imprescindíveis a correção de pH do solo, no intuito de condicionar o solo a faixas considerados ideais do pH (6-6,5).Research, Society and Development2021-05-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1452010.33448/rsd-v10i5.14520Research, Society and Development; Vol. 10 No. 5; e17910514520Research, Society and Development; Vol. 10 Núm. 5; e17910514520Research, Society and Development; v. 10 n. 5; e179105145202525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/14520/13294Copyright (c) 2021 Mateus do Carmo Rocha; Thais Binow Dias; Junimara Sarmento Chaves ; Alisson Rangel Albuquerque ; Milena Pupo Raimamhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRocha, Mateus do Carmo Dias, Thais Binow Chaves , Junimara Sarmento Albuquerque , Alisson Rangel Raimam, Milena Pupo 2021-05-17T18:20:49Zoai:ojs.pkp.sfu.ca:article/14520Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:36.898921Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
