“…In reducing the salt stress, Fe plays a unique role by producing antioxidative enzymes Ghasemia et al, 2014). These antioxidative enzymes include catalase (CAT), peroxidases (PODs), and one isoform of superoxide dismutase (SOD) that act as major scavengers of ROS, thereby enhancing cell defense mechanisms against salinity (Scandalios, 1990).…”

“…However, Manthey et al (1996) reported decreased activity of both CAT and SOD enzymes under Fe-deficient conditions in onion, which was associated with increased susceptibility against stress. Ghasemia et al (2014) suggested defending the role of Fe 2+ amino acid chelates in tomato plants against salinity. Hence, from the above studies, it can be concluded that Fe plays a significant role in alleviating the adverse effects of salinity.…”

Iron (Fe) is a micronutrient that plays an important role in agriculture worldwide because plants require a small amount of iron for its growth and development. All major functions in a plant's life from chlorophyll biosynthesis to energy transfer are performed by Fe (Brumbarova et al., 2008;Gill and Tuteja, 2011). Iron also acts as a major constituent of many plant proteins and enzymes. The acquisition of Fe in plants occurs through two strategies, i.e., strategy I and strategy II (Marschner and Römheld, 1994). Under various stress conditions, Nramp and the YSL gene families help in translocation of Fe, which further acts as a mineral regulatory element and defends plants against stresses. Iron plays an irreplaceable role in alleviating stress imposed by salinity, drought, and heavy metal stress. This is because it activates plant enzymatic antioxidants like catalase (CAT), peroxidase, and an isoform of superoxide dismutase (SOD) that act as a scavenger of reactive oxygen species (ROS) (Hellin et al., 1995). In addition to this, their deficiency as well as their excess amount can disturb the homeostasis of a plant's cell and result in declining of photosynthetic rate, respiration, and increased accumulation of Na + and Ca − ions which culminate in an excessive formation of ROS. The short-range order hydrated Fe oxides and organic functional groups show affinities for metal ions. Iron plaque biofilm matrices could sequester a large amount of metals at the soil-root interface. Hence, it has attracted the attention of plant physiologists and agricultural scientists who are discovering more exciting and hidden applications of Fe and its potential in the development of bio-factories. This review looks into the recent progress made in putting forward the role of Fe in plant growth, development, and acclimation under major abiotic stresses, i.e., salinity, drought, and heavy metals.

“…Improved plant growth and performance, as well as higher yield and quality are obtained by application of aminochelate fertilizers compared to routine chemical fertilizers such as sulfate salts [13]. There is also a superior effect of aminochelates application even compared to other synthetic chelates such as EDTA and EDDHA on many plant yield and quality traits [34,26,12].…”

“…Lime-induced chlorosis is one of the most important plant nutritional disorders, mainly due to micronutrients deficiency, in particular Fe deficiency, affecting many yield and quality parameters. In general routine chemical salts, with high reactivity and low efficiency, are not effective in correction of micronutrient deficiencies especially in the case of iron deficiency [20,35,12]. During the last few decades various chelating agents were introduced and applied in cropping systems particularly in horticultural sections to combat different deficiencies, in which routine fertilizers were not able to correct them.…”

Aminochelate fertilizers are the latest novelties regarding plant nutrition in agricultural production systems. They are part of the modern formulae of fertilizers which are synthesized based on various amino acids, mainly glycine. In recent years, they have had a rapid growth in the marketplace. Their rapid growth in formulations, manufacturing, diversity and application is mainly due to the novel understandings regarding diverse roles of amino acids in plant metabolism. Compared to routine fertilizers or other commercially synthetic chelators such as EDTA; however, aminochelates represent a safer and more efficient form of fertilizer, resulting in better plant performance and less environmental risks. Aminochelates represent effective fertilizers for both soil and particularly for foliar applications. Despite, aminochelates having quickly dominated the fertilizer markets in many countries, there is not enough scientific data and information regarding detailed responses of crops to these types of fertilizers. This in part, may be due to their mixed composition of several nutrient elements, giving various nutrients effects, meaning that conducting scientific experiments and concluding remarks, , would be very difficult. This review provides information concerning different aspect of aminochelate fertilizers including their history, structure, types, value and effects on agricultural crops.
