Optimisation of Loss on Ignition at Soil for Application at School Lab

Abstract

One of the parameters that is used to evaluate soil quality is the content of organic matter, which can be determined as the so-called loss on ignition. The execution of determining loss on ignition is, in principle, very simple, but it is demanding on some laboratory equipment and on work time. This contribution describes the procedures that are a model of the loss on ignition, and it is possible to accomplish them in the school laboratory. Part of the whole contribution is also the evaluation of the accuracy of data obtained by simplified procedures with data corresponding to the original method.
