Plants are dependent on exogenous nitrogen (N) supply. Ammonium (NH 4+), together with
nitrate (NO 3–), is one of the main nitrogenous compounds available in the soil …

Hydroponics is an excellent technique for the cultivation of vegetable crops and other plants,
but organic fertilizers cannot be used in conventional hydroponic systems, which generally …

A high concentration of ammonium (NH4+) as the sole source of nitrogen in the growth
medium often is toxic to plants. The nitrate transporter NRT1. 1 is involved in mediating the …

ABSTRACT Aspects of ammonium (NH4+) toxicity in cucumber (Cucumis sativus L.) were
investigated following growth with different N sources [nitrate (NO3−), NH4+, or NH4NO3] …

Abstract Nitrate (NO3−) and ammonium (NH4+) are the main nitrogen (N) sources and key
determinants for plant growth and development. In recent decades, NH4+, which is a double …

Growth of many species of plants is optimal when the two major forms of N that are
assimilated by plants are supplied at a particular ratio. This ratio is affected by both species …

Ammonium (NH4+) and nitrate (NO3−) are the two forms of inorganic nitrogen essential for
physiological and biochemical processes in higher plants, but little is known about how the …

Acidic tea (Camellia sinensis) plantation soil usually suffers from magnesium (Mg)
deficiency, and as such, application of fertilizer containing Mg can substantially increase tea …

Aims Rice is known as an ammonium (NH 4+)-tolerant species. Nevertheless, rice can suffer
NH 4+ toxicity, and excessive use of nitrogen (N) fertilizer has raised NH 4+ in many paddy …

Sophora japonica is a leguminous tree species native to China. To explore the nitrogen (N)
source preference and its impact on stress tolerance, a hydroponic experiment was …
