For the replacement of peat in growing media, biogenic residues from other processes are often considered as a cost-efficient constituent. However, their chemical and physical properties do not readily permit their use in growing media. In order to solve these quality problems, on the one hand questions arise on suitable strategies for pretreatment and mixing of biogenic residues, and on the other about suitable amendments. Here in the past clays have established as an amendment to peat-based growing media with the aim of balanced nutrient supply, improvement of rewettability and sufficient supply of trace elements. Minerals contained in clays such as iron sulfide or volcanic glasses can lower the pH to an optimal range for plants or cause a continuous supply of plant-available Si. In the project, the preparation for various peat substitutes, the selection of clays and their mixtures will be put on an enhanced scientifically and horticultural basis. In cooperation with partners from circular economy, special clay industry and soil science research, optimum preparation methods of biogenic residues for their use as growing media with storage, shredding, drying and mixing technologies will be developed. For different clays, mineralogical, chemical and physical parameters for selection and processing will be developed. High-quality horticultural substrates will be produced from the available biogenic residues such as compost, fermentation residues, champost and horse manure through targeted preparation and perfectly tuned amendment of clay. Goal is to produce peat-free substrates from biogenic residues, which are based on the quality standards of the RAL 'Quality Assurance Association Substrates for Plant Cultivation' and which are the first growing media to be certified according to the EU Ecolabel.
