Biomass productivity of black spruce trees is strongly limited by soil nitrogen in shallow active layer on permafrost. Trees and mycorrhizal roots are known to absorb amino acids to bypass slow nitrogen mineralization in nitrogen-limited boreal forest soils. However, the amino acid uptake strategy o...
