Loss on ignition

Above you can follow the different steps when performing LOI.

This LOI method is used as a proxy for organic content in the sediment samples. This method compares the weight of the sample before and after ignition. After ignition, all the organic matter will be gone and the difference between the total and the new weight of the sample gives you the organic content of the soil.
