Abstract: Through the experimental study on the fertilizer utilization efficiency of corn under the soil testing and formulated fertilization model, the results show that the utilization rate of N fertilizer is 30.3% and that of K fertilizer is 54.9%, which is close to the national average; the utilization rate of P fertilizer is 9.5% lower, and the technology needs to be improved, so as to improve the utilization rate of P fertilizer.

Keywords: corn; soil testing and formulated fertilization model; fertilizer utilization efficiency test
