for his groundbreaking research of the role of organic nitrogen in the nutrition of trees. The ability of boreal forests to take up atmospheric carbon dioxide and produce wood for industrial uses depends on the availability of nitrogen in the soil. Prof. Näsholm’s research program documented the ability of trees to use amino acid molecules as sources of nitrogen, and that these sources of organic nitrogen predominate in the nutrition of trees in boreal forests. His discoveries have substantial practical importance in sustainable management of forests, e.g., as fertilization concepts in forestry and in production of high quality seedlings in tree nurseries.
