Relations between clay soil, property of which as shown in Table 1,soil water and base exchange capacity were studied. Amounts of Krillium added to soil were 0.01,0.05,0.1 and 0.5%, and those of soil water were 5,10,15,20 and 30%, corresponding to about 25,35,50,60 and 85% of water capacity respectively. By the addition of Krillium, capillary movement in the soil was hastened, when the soil contained water more than 15%, approximate value of hygroscopic coefficient in both systems, Ca and Na. Percolation of water through dry soil was retarded by the addition of Krillium, but it was hastened at 15% of water. Percolation of NH_4Cl solution was more retarded them that of water. Addition of Krillium caused both soil volume in water and base exchange capacity to be increased, while it caused water capacity to be decreased in Ca-system and to be increased in Na-system.
