- ... We carried out mid-infrared (mid-IR) spectral interpretation of soils 0-5 and 5-15 cm deep in selected alternative crop rotations (ACR) treatments and an adjacent native prairie soil. Ashing and spectral subtraction shows that absorbance at 3700-2850 and 1700-1550 cm-1 indicates organic absorbance. Prairie soils, with their greater carbon (C) content, have different spectral properties from the cr ...
