'•T*»HE efficiency of mineral nutrients applied to the J. sandy soils of Florida is largely determined during the immediate growing season (i, 3, 5, 7). The writers (6) have shown that the method of placement , and nature of the cation-anion balance are of major importance in determining the quantity and quality of salts appearing in the leachate. It was found that Ca(NOs)2 was predominant in the soil solution in the presence of high NOg, and apparently retarded the movement of SC>4 until the NOs crest was passed. There was also some indication that the movement of K was depressed at the concentration crest of Ca(NOs)2 as compared to the movement of K at the SC>4 concentration crest. The application of lime was found to increase materially the leaching of SO4. The present work is an expansion of the preceding study to include Na, Mg, and Cl ions.
