%X Traditional models of nutrient cycling assume that soil microorganisms must decompose organic matter, releasing inorganic N, before that N becomes available for plant uptake. But, there is a growing evidences that plant can take up organic N. In the moist tundra of arctic tundra, most wetland are poor inorganic, plant-available nutrients because mineralization is restricted due to low temperatures and anoxic soils. But tundra soils have higher concentrations of water-extractable free amino acids than o...
