Abstract
We describe a soil chemistry sensor for in-situ soil chemistry sensing, the sensor comprising a probe incorporating a first, ion-selective electrode and a second, reference electrode, wherein said ion-selective electrode comprises a first-electrode housing defining a first lumen having an ion-selective plug towards a distal end, said first-electrode including a first conductor in a first electrolyte, wherein said reference electrode comprises a second electrode housing defining a second lumen having a porous reference electrode plug towards a distal end, said second electrode including a second conductor in a second electrolyte, wherein said ion-selective plug and said porous reference electrode plug are within 10 mm of one another, and wherein said porous reference electrode plug and said ion-selective plug each comprise a polymer.
