Abstract

This study introduces a cost-effective optical process to measure the nitrogen (N), phosphorus (P), and potassium (K) in fertilizers that are hydrophobic nutrients using UV spectroscopy and light-absorption techniques. A microcontroller, wavelength-specific light-emitting diodes (LEDs), and a TCS3200 color sensor were combined to estimate the nutrient concentrations using Beer-Lambert law modeling. The calibration of standard solutions such as nitrate nitrogen, phosphate, and potassium oxide shows linear responses with good correlation of concentration (R2 is N-0.96, P-0.97, K-0.95). The maximum absorption peaks at discrete LED wavelengths were experimentally verified with a laboratory UV spectrometer. The findings indicate that the suggested system is a rapidly portable, non-destructive method for measuring fertilizer concentration in soil and can be used in precision agriculture.
