    摘要: A method for mapping distribution of chemical compounds in soil is described herein including inserting a probe into the soil, obtaining spectroscopic data regarding the soil, sampling a core of soil adjacent to the probe locations, dividing the core into multiple depth increments, analyzing the core samples, matching each core sample with a corresponding depth increment of the probe insertions, obtaining data from the probe insertions, dividing the probe insertion data into training, validation, and test categories, resampling spectral variables from the probe insertion data to a wavelength interval longer than a native wavelength interval of an associated spectrometer, normalizing the probe insertion data on a spectrum by spectrum basis, utilizing a machine learning normalization algorithm, standardizing the spectral variables to a common scale by removing a mean and scaling to unit variance, and choosing a model utilizing the test set.
