Aminochelate fertilizers: the new approach to the old problem; a review

Abstract

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.

Nutritional Value and Mineral Concentrations of Sweet Basil Under Organic Compared to Chemical Fertilization

“…These organisms are a major source of various biostimulants including organic acids, amino acids, vitamins, effective enzymes and semihormonal substances that strongly can affect growth and improve plant productivity and nutrient uptake [Dahama 2007, Citak andSonmez 2010]. The released compounds by these microorganisms mainly organic acids, amino acids and phenolics contributes in medium pH reduction and forming chelating bonds with unavailable forms of nutrients, making them more available to plant roots [Marschner 2011, Souri 2016.…”

“…1), the plant response to NPK fertilization is quite expected. This is the best promotion of farmers for more application of chemical fertilizers, which during last decades in conventional farming has resulted in serious challenges including reduced soil quality and fertility, contamination of surface and deep waters, reduced biodiversity and disruption in ecosystem activities [Socolow 1999, Souri 2016. Application of different levels of chemical fertilizers generally results in increase of plant growth, yield and nutrient concentrations [Singh and Ramesh 2002, Anwar et al 2005, Singh and Guleria 2013.…”

“…During last century environmental pollutions and contamination of agricultural food commodities have been linked to unsustainable approaches to production policies [Tabosa et al 1990, Citak and Sonmez 2010, Souri 2016. Application of various fertilizers as well as uncontrolled use of pesticides has caused serious health challenges in ecosystem levels.…”

“…On the other hand, in many semi arid and arid parts of the world organic vegetable production is relatively more difficult than European wet regions [Tabosa et al 1990, Singh and Guleria 2013, Souri 2016. Problems associated with sufficient organic matter and manure supply, high rate of organic matter turnover, infertile and poor structured soils, inadequate water supply and water quality, hot weather and periodic and devastating droughts are some challenges raise to constrain organic production in arid regions.…”

“…Reports indicate that their environmental abundance and bioavailability were found to increase to a hazardous threshold (Gyekye 2013;Sharma et al 2008;Girisha and Ragavendra 2006). Agricultural lands were also affected particularly in arid and semi-arid regions, mainly due to application of wastewater as an irrigation source (Souri 2016;Gupta et al 2010;Li et al 2010).…”
