PORTABLE ELECTROCHEMICAL NUTRIENT TESTING DEVICE FOR SOIL HEALTH MONITORING

The present disclosure proposes a portable, battery operated, calibration free, soil independent electrochemical nutrient testing device for soil health monitoring that is designed for in-field nutrient analysis and aids to monitor soil health accurately on a regular basis. The portable electrochemical nutrient testing device (100) for soil health monitoring, comprises a function generator block (102), at least one screen-printed electrochemical sensor (104), working electrode (106), counter electrode (108), reference electrode (110), plurality of contact pads (112), voltage control module (114), data acquisition module (116), micro-controller unit (118), display unit (120), a processing module (122), and a location intelligence module (124). The portable electrochemical nutrient testing device doesn't require prior conditioning and calibration of the electrodes and does not require complex sample preparation using multiple reagents.
