How can you test the micro and macro nutrients in soil through FT IR?

Fourier Transform Infrared (FTIR) spectroscopy can be used to analyze soil samples for both micro and macro nutrients by detecting specific molecular vibrations associated with various nutrients. The process involves preparing soil samples, mixing them with a suitable matrix (like KBr), and then scanning them with an FTIR spectrometer. By analyzing the resulting spectra, specific peaks can be correlated with the presence of nutrients such as nitrogen, phosphorus, potassium, and trace elements. However, FTIR is typically more effective for organic compounds and may require complementary techniques for precise quantification of inorganic nutrients.
