Results are presented from part of an experiment involving the application of nitrogen, phosphorus and potassium to a pure grass sward which had also received sheep dung and urine. The yield of oven‐dry grass was increased significantly by about 30% by superphosphate application, but only where nitrogen had also been applied at 260 lb: N per acre per annum.
