Methods of soil investigations for agricultural water engineering - Chemical laboratory tests - Part 3: Determination of the loss on ignition and the residue of soil after ignition
The document specifies a method for determination of the loss on ignition and the mass of dry residue of soil samples. Samples are ignited at 550 ?after sieving and drying at 105 ?and the mass is determined by weighing.
