WebThe equation introduced by Mitscherlich has been generally used to express nutrient-yield relationships as follows: y = A(1—e-eb-ex) This paper reports an attempt to apply such a curve to soil nutrient-plant composition relationships, using the wheat plant. For this study soils deficient in phosphorus were selected in four different soil areas. WebApr 13, 2024 · However, for Equation (4) (the generalized Mitscherlich model), we also need to enlarge the problem space to 6, which is equivalent to parameters a, b, c, L, d, and k. Additionally, the parameters of the algorithm were fine-tuned, and the fitness function was modified; this method was effective in achieving this goal due to its intelligence.
