The ob - jectives were: 1) to establish the equations be-tween WB and LOI methods, and 2) to compare the spatial variability of SOM determined using Witryna4 mar 2024 · The loss-on-ignition (LOI) dry combustion method is the routine soil organic matter method used in commercial soil analysis. The amount of soil organic matter is measured directly as the weight loss upon combustion at 360 deg C. The LOI method is simple, affordable, and safe. It also requires no hazardous chemicals.
