WebLoss on Ignition (LOI) analysis is used to determine the organic matter content (%OM) of a soil sample. This is a relatively simple procedure compared to others used to determine %OM. It does not involve the use of any chemicals, only the use of a muffle furnace. LOI calculates %OM by comparing Weborganic matter concentrations (3-55%). Indirect assessment of the organic carbon content or organic matter using a correction coefficient is not very accurate for samples with average organic carbon content.
