Iron Biogeochemistry: Effect of Iron (Fe3+) Fertilization on Global Warming

Author : Amrit Lal Meena, Nisha Lekshmi V, Chethan Kumar G, Amit Kumar, Jairam Choudhary and Lalit Krishan Meena

Iron is the fourth most abundant element and second most abundant metal in earth crust essential for plants and animals. The Fe biogeochemical cycle of agro-ecosystems involves the processes like mineralization, immobilization, oxidation, reduction, hydration and precipitation. Podzolization is a soil forming process in which iron oxides are dissolved and iron is translocated and enriched in the subsoil under the influence of organic ligands. Progressive increase in below ground concentration of Fe has been noticed in response to flooding, with a fourfold increase in the continuously flooded treatment. Transfer and transformation of soil iron for wetland hydro-geomorphological conditions has been widely studied and results showed a positive correlation of amorphous iron with organic matter and soil water content, while it was negatively correlated with soil pH. Changes in redox state of iron and humic substances have been reported due to geophagous microbial degradation of organic matter. Remarkable reduction in annual greenhouse gas (NGHGB) has been observed by many studies as a result of iron fertilizer application.
