Effect of Nitrogen, Sulfur, and Lime on Utilization of Rock Phosphate by Alfalfa1

J. D. Nichols, G. M. Phibbs and L. W. Reed2

Synopsis: Nitrogen and sulfur fertilization did not appreciably affect the uptake of phosphorus by alfalfa from rock phosphate. Alfalfa yield increases due to rock phosphate and superphosphate were not significantly different on unlimed soil. But, on limed soil superphosphate was significantly better than rock phosphate.
