Potassium soil
WebThis 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.
