Sampling of sugarcane [Registered]

The importance of obtaining representative samples from heterogeneous materials and the difficulties involved in doing so are discussed in analytical chemistry texts. Kolthoff et al. (1969) for example note that all the careful work put into a good analysis is wasted if the sample is not representative of the material from which it is taken. These comments are particularly relevant for sugarcane: the stalk itself consists of many parts; in harvested cane green and dry leaves, immature material, soil, stones, roots, cane flowers, rain water can be present.  Draeger et al.
