Soil spectrometer
WebSoil spectroscopy is a method that has the potential of more rapidly and cost-effectively measuring soil properties in the lab and in the field. Soil spectral analysis estimates soil properties by calibrating conventional reference measurements, like wet chemistry soil tests, to the spectral signatures. WebChemical composition of soil organic matter (SOM) is an important determinant of SOM stabilization and soil function. Better understanding of the chem…
