Ny giv for gjødsling med tang og tare?

Summary in the original language of the document

This paper gives an overview of studies conducted at NORSØK, Tingvoll, Norway in the SeaSoil project (2022-2025), especially a trial where high amounts of various seaweeds were applied. The maximum application per unit area over time is regulated by the content of cadmium, which may be significant in brown seaweeds. Soil data indicates that arsenic may still be present in the soil 3 years after application. Potentially toxic elements (heavy metals) are studied in SeaSoil and further results will be published.
