Abstract
Chelates are nutrient-rich compounds that enhance the condition of plant tissues as micronutrients. Micronutrient deficiencies particularly iron (Fe) and zinc (Zn) leads to various problems for plant including chlorosis and necrosis etc. An adequate intake of Fe and Zn etc. is required by the human body. Biofortification of cereals with Fe and Zn is seen as a cost-effective solution to the problem of Fe and Zn deficiencies as well. In recent decades, many chelating compounds have been established and incorporated into agricultural systems. The most recent formulation involves the use of amino acids synthesized with one or more nutrient ions to improve fertilizer efficiency and better respond to environmental conservation. In addition to its primary function as a source of micronutrients, aminochelled are an active nitrogen (N) stimulant in plant nutrition, preventing the negative effects of basic N fertilizers like urea. The use of amino chelates, rather than just chemical fertilizers, has been shown to provide better production and quality as well as higher nutritional concentrations in several experiments. Furthermore, this review sheds light on various aspects of amino chelates fertilizers including types, history, and their effects on agricultural crops. In spite of amino chelates fast dominance in many countries' fertilizer countries, there is not enough scientific data and knowledge on the specific reactions of plants to biotic and abiotic stresses from amino fertilizers.
