SeaSoil Project: Value creation and ecosystem services of European seaweed industry by reducing and handling potentially toxic elements from breeding to soil

  • Overview of the SeaSoil Project

    Promote value creation, including ecosystem services, and further expansion of the seaweed industry in Europe by closing knowledge gaps on PTE in farmed sugar kelp and As in seaweed material applied to soil for fertilisation and enhancement purpose and for carbon sequestration and storage (CSS)

  • Project Objectives

    1) Estimate heritabilities and genetic correlations in contents of Cd, As and I in sugar kelp (Saccharina latissima) from two areas in Norway, and evaluate potential selection response of their reduced contents (WP2)

    2) Study the impact of seaweed application rate and water saturation on the As dynamics in soil to determine chemical reactivity and potential bioavailability of labile As using an outdoor container experiment with different soil types and two crops (WP3)

    3) Estimate the potential of seaweed amendments for CSS in agricultural soils (WP3)

    4) Study the impact of seaweed production on the environment (primarily climate change) using LCA, and conducting a cost-benefit analysis of the seaweed industry, including ecosystem services (WP4)

    5) Study the economic feasibility, and regulatory incentives, for production and use of (residual) biomass from farmed seaweed (WP4)

    6) Ensure multi-actor approach and integrated cooperation, communication and human capacity building in line with Responsible Research and Innovation (RRI) (All 5 WPs)

Impacts of the Sea Soil Project

•Seaweed biomass production has increased worldwide  - 35.8 Mt in 2019,

•European production only 0.8% of this. Still harvests from wild stocks, - 97% of the total volume

•Seaweed farming can secure blue vegetation and blue forests that bind C, absorb P and N
and maintain/increase marine biodiversity

  -> Improved water quality and environmental status

•Mineral fertiliser in agriculture has large environmental footprint 

  -> Sustainable alternatives needed

•Seaweed material may increase plant growth and improve soil structure, biodiversity, C storage  -> Potential value creation and ecosystem service

•Concerns about the high contents of Potential toxix elements (PTE) in seaweed

•Knowledge gaps regarding PTE, I, Cd, As
