Rapid detection method of soil organic matter contents using visible/near infrared diffuse reflectance spectral data

Rapid detection method of soil organic matter contents using visible/near infrared diffuse reflectance spectral data

The effect of different soil particle sizes on the visible/near infrared spectra to detect soil organic matter contents was analyzed. The visible/near infrared spectra of soil samples with the particle sizes of 0.169-2 mm and <0.169 mm were measured at the range of 325-1 075 nm. Then the prin...
