This investigation was undertaken to attain by means of pot cultures and chemical analyses a better understanding of the significance of the degree of base saturation in relation to the growth and mineral composition of certain crops. Two relatively pure mineral colloids, bentonite and kaolin, and a lucastrine orchard soil containing illitic type of clay minerals were used for the studies. Bentonite and kaolin were first electrodialyzed and then mixed with different amounts of pure quartz sand to give different levels of base exchange capacity. Treatments were made to all three cultural media for varying degrees of base saturation with constant ratio between exchangeable bases. Oats and rye were grown in succession in montmorillonitic and kaolinitic media, while peach, soybean, proso, tomato and oats were grown in the illitic soil. Dry weights and contents of certain mineral constituents of oats, rye and tomato were determined. Yield data from the montmorillonitic media showed nearly linear relationship between the degree of base saturation and the growth of the plants. In the kaolinitic media the increase of yield was only noticeable from the first increment of bases, effects above 40% total base saturation being insignificant. The results from illitic soil were intermediate between those mentioned above, i.e., the highest yield of tomato was obtained at the 75% saturation level. The yield data further indicate that the growth of plants was more closely related to the degree of base saturation than to the total supply of exchangeable bases. With the same amounts of bases and at the levels below 60% base saturation, the yields of rye in the kaolinitic colloid were higher than in the montmorillonitic colloid. In the montmorillonitic media, the increase of Ca uptake by the plants from the first increment of Ca was pronounced with only little effects above 30% Ca saturation (or 40% level of total base saturation). The K content of the plants was increased appreciably at only the higher levels of base saturation, while significant increases of the Mg content of the plants occured at lower levels (i.e. below 60% base saturation level). In the kaolinitic media, no appreciable change of Ca and Mg contents of the plants was noticed. This is an interesting contrast to the results obtained with the montmorillonitic media. However, there were definite increases in K content of plants with increasing increments of K at the lower levels of saturation. The higher contents of Ca and Mg in the plants were found in kaolinitic media rather than in the montmorillonitic media provided that the total base saturation level was under 60% of the exchange capacity. On the other hand, the K content of the plants from montmorillonitic media was invariably higher than from kaolinitic media. In the illitic soil, the most marked increase of Ca content in plants occured when the degree of base saturation increased from the 50% to the 75% level. Beyond that point, no appreciable increase was noticed. As the degree of base saturation of illitic soil increased, the K and Mg percentages in plants increased also. Among the conclusions obtained from the experiments, the following are of outstanding significance: 1. Exchangeable cations are not equally available. With the equal supply of total exchangeable cations, their availability varies with the degree of base saturation. Within a certain range, the higher the degree of base saturation, the greater the availability of the exchangeable cation. This affords a theoretical explanation of the advantage of localized application of fertilizers. 2. The availability of exchangeable cations varies with the nature of clay minerals. With the given amount of exchangeable cations and the same degree of base saturation, the individual exchangeable cation held by the clay mineral differs in availability according to the following order: For Ca" and K', kaolinite>montmorillonite>kaolinite. This gives the reason why a montmorillonitic soil should be fertilized with respect to the Ca and K to higher levels than a kaolinitic soil. 3. In order to afford sufficient amount of active cations for the growth of plants, higher degree of ionic saturation is required for Ca" than is for Mg", which in turn should be higher than for K'. The study also discusses, from the theoretical point of view, some of the factors involved in determining the availability of exchangeable bases.

To three cultural media composed of montmorillonitic,kaolinitic and illitic type of clay minerals,treatments were made for varying degrees of saturation of exchange- able calcium,magnesium and potassium with constant base exchange capacity.The effect of complementary ions on the availability of exchangeable Cations was judged from the yields as well as their chemical composition of the plants growing on them. The results are summarized as follows. 1.No difference was noticeable among different types of clay minerals with respect to the effect of the nature of complementary ions on the availability of the exchangeable cations. 2.As a complementary ion,the higher the degree of saturation of calcium,the lower the availability of the exchangeable magnesium.Similarly,magnesium as a complementary ion has also the same effect on the availability of exchangeable mag- nesium as calcium does on magnesium. 3.The availability of exchangeable potassium increases with the increase of the degree of saturation of calcium functioning as a complementary ion to the exchangeable potassium.But,to the contrary,potassium as a complementary ion affects the availa- bility of exchangeable calcium in the reverse direction.Situation is just about the same between the mutual effect of the exchangeable magnesium and potassium. 4.Results from illitic series of the cultural media showed that with respect to the availability of exchangeable potassium,calcium as a complementary ion is preferable to magnesium,and with respect to the availability of exchangeable calcium,potassium as a complementary ion is superior to magnesium. 5.From the results,it seems that under the conditions of the same base exchange capacity and the same amount of exchangeable potassium content,calcium clay will afford more available potassium as compared with hydrogen clay.This gives a new explanation of the disadvantages of the acid soil and adds to the support for liming an acid soil.According to the author's opinion,the reported deficiency of available calcium supply in some of the alkali soils,in which the total calcium content was known to be sufficient,may be explained from the standpoint of the unfavorable effect of the complementary ion (Na) on calcium. 6.Suggestions are made that rational application of mineral fertilizers should be made according to the status of the exchangeable cations of the soil.It is rather the degree of saturation of the exchangeable cations and the nature and proportion of the complementary ions than the absolute amount of the nutrients as such or the total percentage content of them on the soil weight basis,that will count in order to afford sufficient quantities of available cations for the nutrition of the plants.The unit of fertilization rate (dosage) is,indeed,a relative concept (relative to the base exchange capacity) and not an absolute weight or an ordinary percentage concept. 7.Attempts were made to explain the effect of different complementary ions on the availability of exchangeable cations by the concept of exchange bonding energy of the various cations.The explanation is serviceable in limited cases.More work is yet to be done before a satisfactory theory can be found to fully explain the com- plementary ion effect. 8.It is reasonable to doubt whether some of the antagonistic phenomena between cations observed on the plants growing in soil reported by physiologists are actually physiological problems at all.Might not these be just matters of complementary ion effects in the soil?
