Conclusions of Trial:

Avian flax presented the potential for use in remediation of Pb and As in industrially polluted areas and appeared capable of handling soils with excessive Ca, Mg, Fe, As, Zn and Pb levels. It had a particular tolerance for varying environmental conditions as well. Avian flax shows promise as a specific varietal for use as a crop that aids in both soil health and provides a secondary benefit of biomass for use in linen weaving demonstrations but retting water and tissue testing data should be considered for review in some areas cultivated despite the fact that no limits have been set forth for fiber products to date.

 

 Linore flax had notable issues with germination and root establishment. The invasive weed emergence in Linore Plot B trials resulted in some question of its part in remediating activity as Pokeweed has also been noted as a potential phytoremediation species in reviewed documents. Ca:Mg, soil organic matter and carbon as well as soil pH play a significant role in the invasive species and weeds appearing in Plot B. Soil pH and As mobility was the main limiting factor for Plot A. Both sites will be further explored for reductions well below guidelines for long-term viability of this public space.
