Figure 1 - Apparatus for determination of bulk density
(loose) of fine-grained fertilizers
The method is applicable to fertilizers, dry only, which contain a large proportion of particles of diameters less than 0,5 mm. Its principle is pouring the fertilizer from a specified filling device into a specified measuring cylinder of known volume and weighing the contents of the cylinder. If the fertilizer has absorbed moisture during transport or storage, it is necessary to dry it in an environmental chamber.
