Electrochemical attributes and availability of nutrients, toxic elements, and heavy metals in tropical soils
Provedor de dados: 63
Autores: Fontes,Mauricio Paulo Ferreira; Alleoni,Luís Reynaldo Ferracciú.
Electrochemical properties of soils are very important for the understanding of the physico-chemical phenomena which affect soil fertility and the availability of nutrients for plants. This review highlights the electrochemical properties of tropical soils, the behavior and the availability of nutrients, toxic elements and heavy metals in the soil, especially for soils with predominant variable charge minerals. Availability of the elements is related to ionic exchange, solution speciation, and electrostatic and specific adsorptive soil properties. Empirical and surface complexation models are briefly described, and some results of their application in tropical soils are presented. A better understanding of the role of the double diffuse layer of charges...
