Effects of Salinity and NO3:NH4 Ratio on Yield and Quality in Canola (Brassica napus L.)
Notulae Scientia Biologicae, 2009 The effect of salinity and NO3: NH4 ratio (0:100, 75: 25, 50:50, and 25:75) in the nutrient solution on growth, yield quality and N metabolism in hydroponically grow canola (Brassica napus L.) was evaluation.

Leaf-Atmosphere NH3 Exchange in Barley Mutants with Reduced Activities of Glutamine Synthetase [PDF]
, 1997 Mutants of barley (Hordeum vulgare L. cv Maris Mink) with 47 or 66% of the glutamine synthetase (GS) activity of the wild type were used for studies of NH3 exchange with the atmosphere.

Frontiers in Plant Science, 2020 The provision of ammonium (NH4+) and nitrate (NO3−) mixture increases the total nitrogen (N) than the supply of sole NH4+ or NO3– with the same concentration of total N; thus, the mixture contributes to better growth in Brassica campestris.

Growth, ammonium metabolism, and photosynthetic properties of Ulva australis (Chlorophyta) under decreasing pH and ammonium enrichment. [PDF]
PLoS ONE, 2017 The responses of macroalgae to ocean acidification could be altered by availability of macronutrients, such as ammonium (NH4+). This study determined how the opportunistic macroalga, Ulva australis responded to simultaneous changes in decreasing pH and ...

Frontiers in Plant Science, 2023 Inherently, ammonium (NH4+) is critical for plant growth; however, its toxicity suppresses potassium (K+) uptake and vice-versa. Hence, attaining a nutritional balance between these two ions (NH4+ and K+) becomes imperative for the growth of tobacco ...

Transformation of Ammonium Dicyanamide into Dicyandiamide in the Solid [PDF]
, 2002 Ammonium dicyanamide NH4[N(CN)2] was synthesized through aqueous ion exchange. The crystal structure was investigated by single-crystal X-ray diffraction (P21/c, a = 378.67(6) pm, b = 1240.9(3) pm, c = 911.84(14) pm, β = 91.488(18)°, Z = 4).

Characterization of natural Yemeni zeolites as powder sorbents for ammonium valorization from domestic waste water streams using high rate activated sludge processes [PDF]
, 2018 BACKGROUND In this study three natural Yemeni zeolites (NZ1, NZ2 and NZ3) having major minerals such as clinoptilolite and mordenite, were evaluated as low cost sorbents for the removal and recovery of ammonium ions.

Rapid removal of ammonium from domestic wastewater using polymer hydrogels [PDF]
, 2018 To date, technologies to recover ammonium from domestic wastewater from the mainstream have not found widespread application. This is largely due to the low ammonium concentrations in these wastewater streams.
