Putting Paludiculture into Practice: Integration – Management – Cultivation

Background

In Germany, drained peatlands are responsible for 37% of greenhouse gas emissions from agriculture, although they represent only 7% of agricultural land. In addition to emissions, conventional farming leads to soil degradation, subsidence and rising drainage costs. To prevent long-term abandonment and complete loss of productive agricultural land, alternative forms of cultivation are being developed for fen soils at water levels close to the surface: Paludiculture. The joint project Paludi-PRIMA investigates Reed and Cattail as native plant species that are adapted to water-saturated soils, enable peat conservation and have a high value creation potential based on the material use of the biomass.

Project goals

Paludi-PRIMA intends to contribute to putting paludiculture into practice on degraded fen sites. To this end, the project tasks cover a broad spectrum, ranging from basic scientific research to a field trial on approx. 8 hectares and to the elaboration of recommendations for farmers, authorities and politicians. The following questions will be addressed:

• Which species or genotypes of Cattail (Typha angustifolia, Typha latifolia) and Reed (Phragmites australis) are suitable for different site conditions and utilisation lines?
• What influence does site selection and management (water level, nutrient availability and harvest regime) have on productivity and biomass quality?
• What are the costs of switching to paludiculture (site preparation, planting, management, harvesting, drying and storage)?
• How can the economic viability of paludicultures be assessed in dependence of biomass quality and utilisation options
• How can paludiculture be integrated into agricultural policy, approval (water and nature conservation law) and planning processes?
