“…Similar results have been verified by other authors, that the usage of acid solutions, as Mehlich-1 compare to DTPA , has a larger capacity of extracting Zn from soil, in studies involving two soils (Adônis et al, 2009), three soils (Consolini and Coutinho, 2004) and seven soils (Menezes et al, 2010). Other authors have mentioned that in general DTPA solution is better in relation to acid solutions in the evaluation availability of Zn in soils that have or not received the application of this element (Abreu and Raij, 1996).…”

“…For this reason, Silva et al (2003) verified that the quantity of Cu and Zn accumulated in soybean plants in different soils of the State of Paraná correlated better with the content recovered by Mehlich-3 than by Mehlich-1 and DTPA. Menezes et al (2010) observed that the quantity of Zn taken up by maize plants in different limed and unlimed soils of Minas Gerais was significantly correlated with the contents recovered by the extractants Mehlich-1, Mehlich-3 and DTPA. On the other hand, Bortolon & Gianello (2009) observed that 0.1 mol L -1 HCl, Mehlich-1 and Mehlich-3 did not adequately assess Cu and Zn availability for maize and soybean plants in soils of the state of Rio Grande do Sul.…”

“…Se o pH do solo ficar abaixo do adequado, como seria o caso de solos com baixa T, poderia ocorrer toxidez de elementos como Al 3+ e menor disponibilidade de macronutrientes, como sustentado por Melo et al (2011). Por outro lado, em solos com T classificada como boa, o pH tenderia a atingir valores acima do adequado, reduzindo, segundo Melo et al (2011), a disponibilidade de micronutrientes metálicos, especialmente de Zn, que, de acordo com Menezes et al (2010), teria sua absorção diminuída devido ao aumento da adsorção deste nutriente ao solo e à redução em sua solubilidade. Essa pode ser uma das causas de relatos sobre a ineficácia da calagem, que, segundo Silva et al (2007), nem sempre é realizada de forma adequada.…”
