Invitation: Conclusion "TyphaSubstrat"

50% less peat is possible

22/07/2024 The aim of the three-year TyphaSubstrat project - harvesting and utilising cattail as an alternative substrate material for press pot soil in vegetable growing - was to develop a peat-reduced press pot soil with up to 50% less peat. At the final event on 5 September in Darmstadt, the project participants will present their results. These show: 50% peat reduction in pressed potting soil is possible! Presentations and dialogue in the morning at the Forschungsring e.V. in Darmstadt will be complemented by a tour of the practical tests in a vegetable nursery and a young plant farm near Mannheim. Detailed information on registration and the programme can be found here.

TyphaSubstrat focuses on cattail in a mixture with other peat substitute components such as sphagnum, green waste compost and wood for press pots, on which lettuce and vegetables are grown commercially. In addition, special technology for harvesting cattail was further developed in the project, and cattail raw material was analysed with regard to substrate properties, including pesticides and herbicides. By reducing the use of peat and utilising paludiculture biomass, TyphaSubstrat makes a dual contribution to the transformation towards climate-neutral use of wet peatlands (paludiculture) and demonstrates possibilities for sustainable substrate production. The proven suitability of cattail biomass as an alternative substrate offers the industry a new renewable raw material that can be produced regionally. A step towards a long-term secure and climate-friendly raw material supply and a contribution to peatland protection. TyphaSubstrat is funded by the German Federal Ministry of Food and Agriculture via the Agency for Renewable Resources (Fachagentur für nachwachsende Rohstoffe e.V.).
