Abstract: A mathematical model,that simulates the contents of the main ingredients like N,P,K,and grey coal in the special soybean fertilizer,was studied in 4×2 saturation D best design Comparisons between predicated and experimentally observed results of the soybean production showed general agreement Further simulations were performed with five optimal integrated designs for the main ingredients of the special soybean fertilizer(150kg/hm2 at each group interval)and at soybean production ranging between 1200 and 1800 kg/hm2 The best levels of the main ingredients in the special soybean fertilizer were N 38.95-85.62 kg/hm2,P2O5 47.76-106.25 kg/hm2,K2O 14.04-45.17 kg/hm2,grey coal 159.05-318.60 kg/hm2 while the soybean production was above 1800 kg/hm2 The results of the experiment provided a quantitative index and a scientific evidence for the formula of the special soybean fertilizer.
