“…However, few studies have investigated how the effects of N forms can affect the development and partition of root biomass. The high NH 4 + ratios decrease the total N accumulation in the dry matter of species considered as sensitive to excess ammonium, such as Brassica napus L. (Madsen & Pan, ; Pan et al., ) Cucumis sativus (Campos et al., ; Roosta et al., ), Vicia faba L. (Pan et al., ) Triticum aestivum ( Horchani et al., ; Pan et al., ), Solanum lycopersicum (Barreto et al., ), and Oryza sativa and Spinacia oleracea (Silva, Mello Prado, & Ferreira, ), as well as in tolerant species, such as Saccharum spp . (Ishikawa et al., ) and Passiflora edulis (Silva Júnior et al., ).…”

The search for high yield has identified ammonium toxicity as a problem in arable soils world wide. Ammonia toxicity can be suppressed by the use of silicon, but this fact still needs to be elucidated. Therefore, this review aimed to highlight the harmful effects of ammonium toxicity on model plants, and to determine the effects of Si on the mitigation of abiotic stress. Some plant species are considered as tolerant, and others as sensitive to high N concentrations. In sensitive plants, high ammonium concentrations may hinder the plant's development and even lead to the plant's death due to biochemical, physiological, and nutritional changes. Studies have demonstrated that silicon can mitigate or alleviate the deleterious effects caused by the toxic effect of NH 4 + . These findings were attributed to improvements in the physiological and nutritional parameters of plants. Given the importance of ionic balance between N forms for the plant's development, further studies must be performed to detect mechanisms promoted by Si to decrease or mitigate the harmful effects caused by excess ammonium in plants.Agronomy Journal. 2020;112:635-647. wileyonlinelibrary.com/journal/agj2 635

“…However, an advantage of the use of the MFs compared to ROF is the slightly lower ammonium concentrations during mineralization (without and with plants). Too high ammonium concentrations might cause ammonium toxicity, resulting in stunted growth, necrotic leaves, inhibition of the primary root growth, and, in severe cases, even plant death (da Silva et al , 2016). Additionally, it was shown that there is a high correlation between the EC and nitrogen mineralization efficiencies (Fig.…”

“…While low supply of ammonium promotes plant growth, high supply of ammonium causes toxicity, especially when applied alone [1]. Ammonium toxicity can lead to plant growth retardation, biomass reduction, structural changes, the formation of short and dense root systems and even death [2]. In addition, ammonium toxicity inhibits root cell elongation and affects root geotropism by disturbing auxin distribution in root tips.…”

“…The way to alleviate plant ammonium toxicity is to reverse these toxic mechanisms, for instance, by increasing the activity of the ammonium assimilation system, relieving rhizosphere acidification, inhibiting the futile transmembrane ammonium cycling, increasing the supply of other nutrients [1, 2, 13]. Potassium has a significant alleviation effect on ammonium toxicity [4].…”

Ammonium toxicity in plants is considered a global phenomenon, but the primary mechanisms remain poorly characterized. Here, we showed that although the addition of potassium (K+) or nitrate (NO3-) partially alleviated the inhibition of rice root growth caused by ammonium toxicity, the coexistence of K+ and NO3- clearly improved the alleviation via a synergistic mechanism. The synergism led to significantly improved alleviation effects on root biomass, length, surface area, number and meristem cell number. The aberrant auxin distribution in root tips, rhizosphere acidification level and abnormal cell morphology in the root cap and elongation zone caused by ammonium toxicity could be recovered by this synergism. RNA sequencing and the weighted gene correlation network analysis (WGCNA) revealed that the mechanism of this synergism involves cellulose synthesis, auxin and gibberellin metabolism regulation at the transcription level.
