Characterization of ion-selective electrodes for an on-field soil nutrient analysis system

There is an established need for more careful application of soil nutrients and fertilizer to maximize crop yield for an ever-growing population. This study focuses on the manufacturing and characterization of ion-selective electrodes (ISEs) to further study if they could be used to reliably measure soil markers like nitrate, phosphate, potassium, and pH for farming applications. Research into a low-cost design for a soil nutrient analysis system to characterize the viability of farming soil has already begun through proof-of-concept prototypes and testing. This study builds upon such early-stage testing. The goal of this investigation was to build an understanding of the accuracy of these ion-selective electrodes in soil samples. To arrive at the end goal of this investigation, we divided this project into three main stages for these nitrate, phosphate, potassium, and pH ISEs.
