Abstract/Contents:"Most soils contain relatively large amounts of the essential element for plant growth-potassium (K+); often as much as two percent of the weight of the mineral portion. At the same time the concentration of potassium in the soil solution from which the grass draws its needs may be only 50 to 100 ppm. This relationships illustrates the reason why the total chemical analysis of a soil has little correlation with its ability to supply grass with a nutrient and why soil testing procedures were developed which were more closely related to plant growth." Discusses the portion of potassium in the structure of clay minerals; exchangeable potassium in association with cation exchange; and potassium fertilizers.
