Rooted in science

This curated research library brings together decades of scientific studies exploring organic nitrogen use in plants, with a particular focus on arginine as a novel and highly efficient nitrogen source. The collection spans work on boreal forest species like Scots pine and Norway spruce, agricultural crops, and model plants such as Arabidopsis thaliana.

These papers investigate:

  • Nutrient uptake pathways for organic and inorganic nitrogen forms.

  • The physiological, ecological, and microbial interactions influenced by arginine.

  • Field and greenhouse experiments comparing growth performance, nitrogen use efficiency, and nitrate leaching under different nitrogen regimes.

  • The role of nitric oxide signaling in root growth and plant–microbe partnerships.

  • Innovations such as arginine–iron–hexametaphosphate complexes and co-factors that enhance arginine’s benefits.

Together, they provide both the evolutionary context (why plants respond strongly to arginine) and the mechanistic insights (how arginine delivers its benefits), forming a strong foundation for advancing sustainable fertilization strategies in forestry, agriculture, and horticulture.
