Abstract

Industrial agriculture, while necessary to meet current food production needs, can have damaging effects on the environment and local water supply. For monitoring purposes, Raman spectra of common fertilizers in solution are measured and presented. Raman spectra of the fertilizer species combined with data from Inductively Coupled Plasma Emission Spectrometry (ICP-AES) is used to construct an empirical model of contaminant concentration. This work expands upon the authors’ prior work in Raman Spectroscopy of Common Fertilizers in Bulk and in Aqueous Solution, which was presented during the virtual sessions at OSA Optical Sensors and Sensing Congress in 2021 (AIS, FTS, HISE, SENSORS, ES).
