Climatic and agronomic variables are shown to be more closely related to yield response of winter wheat to phosphorus than is NaHCO3-extractable P2O5. It appears that soil tests alone, or in combination with climatic and agronomic variables, are presently of limited value for predicting yield response of dryland winter wheat to phosphorus in the Southern Great Plains.
