[Excerpt] Iron (Fe) is an essential element for the proper development of life. Plants require Fe for chlorophyll synthesis. However, due to the lack of Fe, plants grown in alkaline calcareous soils are very susceptible to a symptomatic array named iron-deficiency induced chlorosis (IDIC). The inappropriate chlorophyll production results in the reduction of crop yields with major implications in many agricultural regions worldwide. Organic chelating agents, namely aminopolycarboxylic acids (APCAs), are adequate for IDIC amending. However, the low biodegradability of such compounds raises several environmental concerns. Therefore, the replacement of APCAs by new more environment-friendly alternatives is needed. [...]
