One of the most controversial and important areas of research on kinetics of soil chemical processes is methodology. Two basic techniques have been used-batch and flow. Differentiating between chemical exchange and mass transfer as rate-limiting steps is relatively easy since most ion exchange processes on soils, clay minerals, and humic substances are diffusion-controlled. The lively and controversial literature concerned with kinetics and mechanisms of feldspar weathering is discussed. The use of spectroscopy to ascertain mechanisms of chemical weathering is a powerful tool and one that soil chemists need to use more.
