Mar 18, 2010 · The nitrogen sources taken up by higher plants are nitrate or ammonium as inorganic nitrogen sources and amino acids under particular conditions of soil composition. Nitrogen assimilation requires the reduction of nitrate to ammonium, followed by ammonium assimilation into amino acids (Fig. 2A).

Jan 7, 2022 · Nitrogen is an essential macronutrient for plants, where its availability is a determinant of plant productivity (Chen et al. 2020). Nitrate (NO 3-) and ammonium (NH 4+) are the two major forms of N that are absorbed by plants; however, both forms are in short supply in agricultural and natural ecosystems (Crawford and Forde 2002).
Jul 30, 2024 · Soil extractable nitrate, ammonium, and organic nitrogen (N) are essential N sources supporting primary productivity and regulating species composition of terrestrial plants....
Apr 19, 2018 · Plants that grow in N-rich environments have higher internal N concentrations and a higher relative growth rate, as described by the N productivity concept. When supply of nitrate N is interrupted, growth is maintained from storage pools of unassimilated nitrate for a limited time.
The predominant sources of nitrogen for higher plants are NH4 +, NO3 - and N2. In most forests, where soils are acidic and low in nitrogen, NH4 + is the major nitrogen source. In agricultural soils, NO3 - is the...
