| Abstract: | This paper originally deals with the method establishment of regional ecological balanced fertilization model by using the data of regional fertilizer field experiments. Therefore, a bridge for information exchange was built to span diagnastic parameters of ecological balanced fertilization model and parameters of existing fertilization models. A plot fertilization model was established based on the tested value of soil available nutrients and plot characteristics. The transform was realized from the regional fertilization model into the plot fertilization model. |
