Soil type was found to be so important in determining the calcium and magnesium content of alfalfa plants at different stages of growth (5)3 that a study of its effect upon additional important elements appeared advisable. One of the elements considered was potassium, and data showing the variations in this element which occur {n alfalfa plants at different stages of growth when grown upon different soil types are reported in this paper. This analysis made possible not only a study of variations in the amounts of potassium present in the alfalfa stems and leaves and in their juice, as affected by soil type, but also acomparison of the potassium-calcium ratios in plants obtained from different soil types with a possible explanation of the observed differences.
