AFFECTED BY SOURCES OF CALCIUM AND PHOSPHORUS IN COMBINATION WITH OTHER FERTILIZERS ON SEVERAL SOILS R. E. BLASER, G. M. VOLK, AND F. B. SMITH THE early development of the livestock industry of Florida has been greatly limited by the low productivity and quality of the native wire grass pastures which have been the major source of forage. If intensification of the industry is to be brought about, it can be only by fertilization and planting of more highly productive pasture plants. Approximately 400,000 acres of improved pasture grasses, such as carpet, Dallis, Bahia, and Bermuda, have been planted during the past 3 years. Only a small acreage of pasture legumes has been used because the adaptation of these crops to Florida soils and climate is not as yet fully understood. Clovers should have a prominent place in Florida pastures because they not only improve the quality and quantity of the forage but also furnish feed during the late winter and spring when it is very much needed. The success of growing clovers on sandy soils of Florida depends upon selection of soils with ample moisture during the growing season and on fertilization with appropriate sources of the elements calcium, phosphorus, and potassium. Investigations to compare the value of different sources of calcium and phosphorus have been under way since 1938. This paper is a preliminary resume of a portion of the work carried on during the 1940-41 season.
