Última Depth distribution of exchangeable aluminum in acid soils: A study from subtropical Brazil Agronomy Rabel, Diego Oliveira; Motta, Antonio Carlos Vargas; Barbosa, Julierme Zimmer; Melo, Vander Freitas; Prior, Stephen Arthur. Due to potential crop toxicity, high aluminum (Al) availability requires increased attention when preparing agricultural soils. However, research examining the relationship between depth distribution of Al and soil weathering has received little priority in Brazil, particularly regarding the number of soil profiles investigated. This study analyzed 38 acid soils selected from Soil Surveys in southern Brazil to identify and isolate the effects of organic and mineral components on depth distribution of exchangeable Al extracted with KCl (AlKCl). These soil profiles were divided into the following three groups based on AlKCl depth distribution: Group I – decrease with depth; Group II – little variation with depth; and Group III – increase with depth. High... Tipo: Info:eu-repo/semantics/article Palavras-chave: Soil Science; Agronomy Ki index; Organic matter; Smectite; Kaolinite; Al oxides; Lime requirement.
