Synopsis On a Bridgehampton fine sandy loam satisfactory stands of Ladino clover were maintained with a minimum application of 60 pounds P 2 O 5 and 120 pounds K 2 O per acre per year over a 4‐year period. Large initial applications of phosphate were not as effective as similar amounts divided over 2 or 4 years. No accumulation of extractable phosphorus was found in the soil at any level of phosphate application. Removal of potassium by the crop approximately equalled the 120‐pound K 2 O application. Excessive plant uptake and soil accumulation of potassium resulted at 240 pounds K 2 O per acre.
