The increasing biological waste treatment (composting) in Germany provides now and in future sufficient quantities of composts for the most different markets. However a closed loop management is only sensible if the produced composts can be utilised in a profitable manner. For the time being the Stender GmbH, as a manufacturer of growing media, is exclusively interested in growing media quality composts with the RAL compost quality label of the German Compost Quality Assurance Organisation BGK.
On account of this aspect the present lecture does not treat with the utilisation of composts in the areas:
- Secondary raw material fertiliser for field cultivation
- Singular application in gardening and landscaping
- Growing media for gardening and landscaping
but only the use of growing and potting media quality composts in commercial horticulture and for the production of flower mould is discussed here.
