Guidance and protection

The RAL quality mark provides guidance and helps to avoid making poor purchases that are costly. Our task is to process and monitor the implementation of the RAL Quality Assurance for bark, growing media, potting soils, growing media constituents, expanded clay for use as a growing medium, substrates for green roofs and substrates for tree planting. In other words, the award of the RAL quality mark certifies the quality of these items.

Information

One of the key duties of Gütegemeinschaft Substrate für Pflanzen e.V. is to pursue a sound information policy vis-à-vis members and consumers as regards quality assurance and the application of the products in question.

Bodies of expert members

At the core of the association’s quality work are the quality commissions of Gütegemeinschaft für Pflanzen e.V. that are organised in three divisions. These bodies are made up of independent scientists and producers’ representatives. They draw up quality criteria and methods of quality assurance and monitor the awarding of quality marks and compliance with the quality parameters. The commission members’ different backgrounds guarantee independence and close liaison between scientists, researchers, and practical producers.
