Mitigation of ammonium toxicity by silicon in tomato depends on the ammonium concentration
(Taylor & Francis As, 2016-01-01)
Ammonium toxicity in hydroponically grown crops can affect tomato development. However, it has been shown that the silicon (Si) attenuates ammonium toxicity in plants depending on the plant species, the stage of development ...
Deleterious effect of ammonium extraction from soil assisted by ultrasound
(Elsevier, 2004)
Ultrasound has been used to assist extraction procedures from solid samples based on the decrease of gradient concentration in the vicinity
of particulate matter and the microjet produced during cavitation. In the present ...
Absorption of nutrients, growth and nutritional disorders resulting from ammonium toxicity in rice and spinach plants
(United Arab Emirates Univ, 2016-01-01)
Excess nitrogen in the ammonium form may induce different nutritional disorders in plants depending on the species cultivated. The present study sought to evaluate the accumulation of nutrients, growth and visual symptoms ...
Scandium fluorides
(1997-11-14)
A new modification of scandium fluoride has been synthesised. The compound is deficient in fluorine, with the composition ScF2.76. It belongs to the tetragonal system, lattice parameters being a = 3.792 and c = 6.740 Å and ...
Impact of nitrate and ammonium ratio on nutrition and growth of two epiphytic orchids
(2018-10-01)
Phalaenopsis and Dendrobium do not grow and flower well with 100% ammonium (NH4-N); and there are detailed studies on the effects of nitrate (NO3-N) and ammonium ratios on the flowering, but no information about accumulation ...
Use of ammonium chloride to prevent urolithiasis in sheep[Utilização do cloreto de amônio na prevenção de urolitíase em ovinos]
(2021-01-01)
Urolithiasis has a high incidence among confined sheep. It is multifactorial and may cause economic damage. Our aim was to determine the capacity of urinary acidification using ammonium chloride in sheep. Twenty-five ...
Standard molar enthalpies of formation and lattice energies of 1-methylethyl, n-butyl and 2-methylpropyl ammonium halides
(Elsevier Science BvAmsterdamHolanda, 1998)
Development and application of an electronic tongue for detection and monitoring of nitrate, nitrite and ammonium levels in waters
(2013-09-01)
This work presents the first study and development of an electronic tongue analysis system for the monitoring of nitrogen stable species: nitrate, nitrite and ammonium in water. The electronic tongue was composed of an ...
