Spectral Discrimination of Macronutrient Deficiencies in Greenhouse Grown Flue-Cured Tobacco.

Remote sensing of nutrient disorders has become more common in recent years. Most research has considered one or two nutrient disorders and few studies have sought to distinguish among multiple macronutrient deficiencies. This study was conducted to provide a baseline spectral characterization of macronutrient deficiencies in flue-cured tobacco ( L.
