In a study carried out during the 1955-56 season near Lincoln, applications of superphosphate to a stand of rose clover increased forage production from 778 pounds per acre to 3,300 pounds per acre—over 300%—and improved forage quality by increasing the protein content 70%, from 8% up to 14%, and the phosphorus level in feed 66%, from 0.15% to 0.25%.
