Cadmium availability and accumulation by lettuce and rice

Bruno Fernando Faria Pereira, Danilo Eduardo Rozane, Suzana Romeiro Araújo, Gabriel Barth, Rafaela Josemara Barbosa Queiroz, Thiago Assis Rodrigues Nogueira, [...]


Among the toxic elements, Cd has received considerable attention in view of its association with a number of human health problems. The objectives of this study were to evaluate the Cd availability and accumulation in soil, transfer rate and toxicity in lettuce and rice plants grown in a Cd-contaminated Typic Hapludox. Two simultaneous greenhouse experiments with lettuce and rice test plants were conducted in a randomized complete block design with four replications. The treatments consisted of four Cd rates (CdCl2), […]

Application of lime with different reaction degrees: chemical changes in soil under corn

Suzana Romeiro Araújo, José Alexandre Melo Demattê, Fernando José Garbuio


With acidity correction, important nutrients for the corn development become more available to the plants, increasing yield. The objective of this study was to evaluate chemical changes in two soils and corn dry matter yield as affected by lime application with different degrees of reaction. The experiment was carried out in a greenhouse on a Oxisol and a Quartzpsament. Three rates of three commercial limes were applied, one with mean reactivity A (RE = 85.7 %; PRNT = 88.3 %), […]
