Analysis of compost and fermentation products

The use of compost and fermentation products as fertiliser and for soil improvement is attractive in many ways.

An independent and regular quality control, such as that carried out by the Bundesgütegemeinschaft Kompost e.V. (BGK) or QLA (Quality Assurance Agricultural Waste Utilisation) is of great importance for producers in the recycling industry. The end user is thus provided with a product that demonstrably meets the high standards of quality assurance and is identified by appropriate seals, e.g. that of the BGK.
