The influence of sulfur on the yield and composition of clovers fertilized with different soruces of phosphorus
1947
Bledsoe, R.W. | Blaser, R.E.
A grass and clover test was established on a virgin Leon fine sand near Gainesville, Fla. The soil is typical of a large portion of the flat pine land of peninsular Florida. Yields of red and black medic clovers were highly significantly increased when sulfur was added to fertilizers which contained basic slag, rock phosphate, and phosphoric acid (85% ortho) as the sources of phosphorus. Yields were not significantly increased when sulfur was added to fertilizers containing superphosphate (20%). Sulfur fertilization had little influence on the growth and yield of Pensacola Bahia grass. Clovers fertilized with sulfur had a higher nitrogen and a significantly higher percentage sulfur content. Results indicate that the natural supply of sulfur, in the rural areas, might be insufficient for the normal growth of clovers on the virgin Leon sandy soils.
