SODIUM SALTS 337 dry matter of the plants were enriched in magnesia andpotash, but became poorer in lime, sulfuric acid, and phos-phoric acid; and upon applying sodium chlorid a stillmore striking change in the same direction ensued. Onthe other hand, Storer x cites Dyer as authority for thestatement that common salt seems to be needed to bringout the action of phosphates and nitrates, yet from ob-servations by various experimenters it would appear thatthere are many conditions under which common salt is.

It is apparent, therefore, that the effect producedhinges upon the peculiar conditions which exist in anygiven case. It has been shown by various experimenters that uponapplying calcium salts to ordinary soils, considerableamounts of potash are often rendered soluble, and thehigh efficiency of sodium chlorid in this respect, underexaggerated conditions, has been shown by , Muntz and Girard hold that if sodium chlorid 1 Agriculture, II (1897), 595. 2 Quorta Seine 17, D
