Recovery of applied phosphorus by 11 oat crops ranged from 51 to 72%, and recovery by the first crop was less than 20% from the silt loams and about 35% from a sand. Total percentage of applied phosphorus recovered by cropping and acid and alkali extractions combined ranged from 74 to 100%. Phosphorus applied at 22 to 589 ppm. to Spencer silt loam gave nearly the same percentage recovery by the 11 crops.
