Can you regulate the NPK value of the final granule? What values can be reached?

The NPK value of the final granule, can be regulated with the formulation of the wet/pasty materials to be dried/granulated. For example, to increase P in the final granule, struvite, DAP, phosphoric acid, or bone meal could be added before granulation.

With only organic materials, NPK values can reach from 1-1-1 to 10-10-10. If mineral products are added, then it can reach up to 11-15-11 or 8-20-5.
