| Abstract: | Fertilizer effect function method is commonly used in soil testing and formulated fertilization technology. The 3414 fertilizer experiment was taken to introduce how to acquire formulated fertilization parameters. Three main procedures include establishing the data set about the model variables, fitting the fertilizer response model and calculating the fertilization parameters. |
