THE feasibility of measuring the activities of a monovalent and divalent cation in the same system by means of the clay membrane electrode technique has been shown previously (5( 6, 2). Those studies showed striking differences in cationic interrelationships with the different clay minerals. The present paper is concerned solely with the clay mineral beidellite (Putnam subsoil). It deals not only with a comparison of the two mono-divalent systems, potassium-calcium and sodiumcalcium; but in addition is concerned with the monomonovalent systems, potassium-sodium, as well as with a very limited study of the mono-mono-divalent series, potassium-sodium-calcium. This is another effort to throw more light upon cationic interrelationships presumably existent in the plant root environment. The clay membrane offers a technique for measuring these mutual effects to which the plant root is subjected in extracting its inorganic sustenance from the soil.
