X-Ray Fluorescent and Mid-Infrared Spectroscopic Analysis of Tomato Leaves

This study aims to develop a simple, rapid, simultaneous and quantitative method for evaluating nutrimental elements of the plant vigor using X-ray fluorescent (XRF) and mid-infrared (MIR) spectroscopy. Tomato, which is one of the typical agricultural products cultivated by hydroponics, was used as the sample, and the leaves would be an index of the nutrimental conditions. We developed the quantitative methods to analyze the XRF and MIR spectroscopic information, and studied the effects of the cultivation conditions on the nutrient information between branches of a trunk. The experimental results presented a great potentiality to obtain the nutrient information on the chemical elements such as Ca and the organic components such as the nitrogen in the plural modes using the both spectroscopic methods. This study presents an important step in the development of XRF and MIR spectroscopic analysis of the plant vigor in the agricultural fields
