Citrus is the most important agricultural crop in Florida. Heavy reliance on agricultural chemicals and low efficiency of fertilizers have raised many environmental and economic concerns. In this study, a nitrogen sensing system for citrus leaf will be developed. Based on chlorophyll and protein absorbance bands, the sensing system will cover wavelength ranges of 620-950 nm and 1400-2450 nm. A reflectance housing was designed to block environmental noise and to ensure single leaf measurement. Adoi:10.13031/2013.19772 fatcat:sdltcbuiqfaahoabeoknhu6ije
