The widespread use of NO(3)(-) fertilization has had a major ecological impact. NH(4)(+) nutrition may help to reduce this impact, although high NH(4)(+) concentrations are toxic for most plants. The underlying tolerance mechanisms are not yet fully understood, although they are thought to include the limitation of C, the disruption of ion homeostasis, and a wasteful NH(4)(+) influx/efflux cycle that carries an extra energetic cost for root cells.

- The study investigates the impact of the urease inhibitor NBPT on nitrogen metabolism in pea and spinach plants grown hydroponically with urea as their only nitrogen source.
- The results indicate that NBPT significantly affects pea plants more than spinach, with noticeable inhibition of urease activity, increased urea levels, and decreased ammonium content, leading to impaired nitrogen assimilation.
- In spinach, the absorption of NBPT is lower, resulting in minimal effect on urease activity, suggesting species-specific responses to the inhibitor's application.
