A Method for Incorporating Soil Test Measurements Into Fertilizer Response Functions1

  1. William G. Brown,
  2. T. L. Jackson and
  3. Roger G. Petersen2



A method for estimating the proportional equivalence of an applied nutrient to the corresponding nutrient existing in the soil is presented.

An application of the method to lime and alfalfa experimental data is presented. Possibilities and implications of the procedure with regard to fertilizer recommendations are briefly discussed.
