Objective
- Learn and apply the physical-chemical and hydraulic principles that govern the dynamics of solutes in
the soil.
- Develop in students the ability to critically analyze problems related to the dynamics of solutes in the
soil, based on scientific works in the area.

Content
The soil solution. Chemistry of the soil matrix surface. Electrochemistry of the solid-liquid interface. Ion
exchange capacity. Flow of ions in soil: miscible displacement; physical processes of solute movement in
soil; types of solute flow; breakthrough curves. Mathematical models for movement of solutes. Soil ion
flux experiments in columns under laboratory conditions; use of radioactive and stable tracers; soil
solution sampling in the field. Nutrient leaching. Determination of nutrient balance components in an
agricultural crop using nuclear techniques.
