Physical Chemistry of Soil Potassium
Abstract
This chapter presents a comprehensive and review of the chemistry and mineralogy of soil potassium (K). In soils, K is also present in fixed form upon reacting with weathered micas, vermiculites, allophane, and zeolites. The intensity of the weathering reaction decreases with increasing depth in soil profiles. Parra and Torrent developed a procedure for determining quantity-intensity (Q/I) relationships in a continuous manner using a K+-selective ion electrode. The influence of oxalic and citric acids on the dynamics of K+ release from micas has been observed. The major clay minerals responsible for K fixation are the expanding 2:1 types such as montmorillonite, vermiculite, and weathered micas. A number of research endeavors in the area of soil K chemistry and mineralogy need investigation. Perhaps the biggest challenge is to model K reactions in the field that must involve the kinetics of K reactions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
