Nitrogen's Importance to Plants

Why is nitrogen important (500 × 500 px)

:bulb:About 1-5% of total plant dry matter consists on nitrogen, which is the
second highest required element in plants, second only to carbon. Nitrogen is
essential for plant metabolism as a constituent of proteins, nucleic acids,
chlorophyll, co-enzymes, phytohormones and secondary metabolites. When taken
up as either ammonium or nitrate, nitrogen is assimilated into amino acids in
either the roots or shoots.

:pushpin: Research Highlights:
:arrow_forward: The availability of nitrogen to roots is a decisive factor for plant growth.
Atmospheric N2 is only available to plants that are capable of forming
symbiosis with N2-fixing bacteria.
:arrow_forward: In addition to inorganic nitrogen acquisition, uptake of organic nitrogen
also contributes to plant nutrition. Organic nitrogen is the main form of
nitrogen in soils: in the organic matter and in the form of peptides and
proteins, amino acids, and the urea.
:arrow_forward: To achieve efficient plant growth, development, and reproduction, adequate,
not excessive, amounts of nitrogen are required. Plants that are deficient in
nitrogen display stunted growth with narrow leaves, a pale green or even a
pale green or yellow coloring, and a low canopy.

:dart:Generally, a uniformly high nutrient supply suppresses root branching.
However, when overall nitrogen availability is limited, plants may respond by
enhancing lateral root development into nitrogen-rich patches.

This article is pretty out of date already theres a way better nitrogen study done with cannabis and nitrogen availability from a few months ago that had alot of new insight in nitrate vs ammonia in plants both in soil and other mediums.
