Abstract text

One of the key limitations to agricultural production in many ares of the Arctic region is the lack of nutritious growth substrate - soil. There are, however, abundant sources of components that with proper processing techniques can produce nutritious, healthy soil via composting. Highly interesting local resources include seaweed, woody materials e.g. from construction and housing projects, silt from riverbeds, and chitin-based waste from processing of shrimp and other marine food items. With suitable processing, these ingredients should produce excellent compost, with very interesting bioactive properties based on the chitin-fragment. The potential of this technology for arctic communities is discussed, and possible ways forward proposed.
