Developing of a Spectral Library for Prediction of Soil Properties: Application of X-ray, Laser and Infrared Analytical Techniques

Virtually everything on earth is anchored on soil and directly benefits from it; be it the natural environment, the flora and the fauna, or the built environment.  It is no wonder therefore that soil is one of the most studied natural resource.  Soil studies, and indeed its various methods of analysis, have come a long way.  For instance the determination of particle size distribution in a soil sample has developed from the traditional and cumbersome sieve analysis, in conjunction with the hydrometer analysis method, to the now results reproducible laser technology particle size analyzer.


Traditional, and still conventional methods in many developing countries, tend to be tedious, cumbersome, painstakingly slow and costly while their results are generally not reproducible.  Newer and more technologically advanced soil analysis techniques tend to mitigate this and more.  Data from these newer soil analysis methods, for example Total X-ray Fluorescence,

X-ray Diffraction and Laser Diffraction Particle Size Analyzer, can be calibrated into infrared reflectance spectra to usher in a soil attributes prediction model for a particular region, in a previously sampled and geo-referenced area, at just the touch of a button.  In this way, engineers, agriculturists and environmental managers can fast acquire soil attribute data more accurately, cheaply and conveniently thus bringing down project costs significantly.
