“…In the first place, high concentrations of specific ions such as Na + are toxic to plants and cause physiologic disorders. Secondly, the presence of salts decreases water root uptake (Bohn et al, 1979;Aguirre, 1993;Pankhurts et al, 2001;Atlas & Bartha, 2002;Bernstein & Kafkafi, 1996;Haynes & Rietz, 2003). And thirdly, certain ions have a negative effect on the solubility of other ions and on microbial biomass activity, e.g., protein synthesis and respiration (Giambiagi & Lodeiro, 1989;Aguirre, 1993;Atlas & Bartha, 2002;Sardhina et al, 2003).…”

“…Coeficiente de curtose dos atributos dentro de cada compartimento tendem a apresentar menor CTC e maior possibilidade de estabilização do Al na estrutura de óxidos secundários (gibbsita) (Silva et al, 2008;Motta & Melo, 2009). No compartimento inferior, com solos mais desenvolvidos, apesar dos altos valores de amplitude e dos coeficientes de variação (Quadros 2 e 3), os teores máximos de Al 3+ foram inferiores aos observados nos demais compartimentos (Quadro 1), o que confirma a relação negativa entre grau de intemperismo e acidez potencial trocável do solo (Bohn et al, 1979;Motta & Melo, 2009). Por estar em uma área de preservação ambiental (APA do rio Iraí), não se usam insumos agrícolas na Fazenda Experimental da UFPR, o que descarta a possível relação inversa entre teores de Al 3+ e correção dos solos.…”

“…Because of the small size of its atom and ion, the behavior of lithium is transitional between the behavior of the alkali metals and that of the alkaline earth metals. These groups present a high ionic potential (ratio of ion radius to ion charge), which implies that lithium is expected to be highly soluble and more easily weatherable (leachable) than transition metals, aluminum cations, and oxyanions (15).…”
