There are two methods of making a general nutritional diagnosis of plants. One is a visual diagnosis based on experience, and the other is a sap analysis of a stems and leaves. Many years of training and experience are needed to make a visual diagnosis, whereas the chemical analysis of a sap also takes a long time to obtain results.<BR>Therefore, we have studied the relationship between leaf electric potential and the nutritional condition of plants. We found that the inorganic nutritional condition (N, P, Mg) of a tomato can be diagnosed by examining of the three dimensional distribution of three alternating current components (30.0, 13.0 and 20.0Hz) of leaf electric potential.
