Claim 0:
1. A method of validating a test for estimating the organic carbon content of soil or changes in organic carbon content of said soil over time in which a first sample of said soil is taken from a selected location and heated using Loss On Ignition (LOI) to remove organic materials including organic carbon from said soil sample by burning off or oxidising said organic materials, said method comprising the steps of taking at least one further sample of soil from a location immediately adjacent to, and having the same geological structure as said selected location, said sample having or being treated to have minimal organic material content, adding to said further sample, a predetermined quantity of an organic material to provide a second sample, heating said second sample containing said quantity of organic material using Loss On Ignition (LOI) to burn off said quantity of organic material, and monitoring the change of weight of said second sample due to the burning off of said organic materials.
