The Relationship

The non-invasion electrical process tomography of plant tuber or root is a new research field in the accurate cultivation of plants. Tuber Electrical Resistance Tomography (TERT) is aimed to extend the application of the technology into agriculture, which can help improving and breeding new varieties of the crops. This paper mainly studies excitation & measurement strategy. Especially the influences on distribution of sensitive field brought by the width and numbers of the array electrodes in the soil environment are analyzed. Besides, the relationship between the electrical conductivity and the measured boundary voltages is also discussed.
