Abstract
Considering the type of disturbance applied in an electrokinetic technique, a low intensity constant electric field, and the effects that this disturbance generates: motion of charged species; this technique can be considered as a characterization tool of porous materials that are in contact with ions in solution, as is the case of soil and compost.
While this electrokinetic tool has been focused mainly as a possibility for environmental remediation, mobilizing charged pollutants, it could be useful also to analyze the transport of nutrients in soil or compost. This process depends on the various equilibria established inside these materials, which could result as an effective method for characterization.
Compared with traditional methods in soil characterization, electrokinetic tool is characterized by its simplicity, low cost, and the possibility of obtaining a set of relevant parameters in a simple experiment.
This chapter presents results obtained by studying soils of Tenerife, Spain, and compost samples from Colombia with different composition.
