Development of a Polypyrrole Modified Gold Microelectrode for Soil Nitrate Detection

Soil nitrate is an important item in soil testing for formulated fertilization. Conventional soil nitrate detection methods are reliable, but time-consuming and expensive. In this paper, a polypyrrole modified microelectrode array was developed for rapid detection of soil nitrate. The microelectrode array was fabricated using a micro-fabrication process.
