Example for mineral solid fertiliser

For fertilisers in a solid aggregate condition, as a rule mineral solid fertilisers, the specific surface plays an important role. Depending on this value, a different behaviour of the fertiliser appears after spreading. Important points to test are particle size and macro-structure of the single grains. During a classic screening analysis the granulate from the rotary kiln or pelletising plate are partially destroyed. Moreover for assessing macrostructure, an additional test is necessary. The HAVER CPA 2-1 provides a complete analysis and all values are available.
