Nanosiderite is effective to alleviate iron chlorosis in ...

2012-4-1  At harvest, the SPAD for the plants fertilized with the highest siderite dose (1.40 g kg-1) did not differ significantly from that for FeEDDHA-fertilized plants. Our results suggest in summary that siderite is effective in preventing iron chlorosis and has a long-lasting effect, as the likely result of the high specific surface and high solubility of the crystalline Fe oxides resulting from its oxidation.

The chemistry of iron in soils and its availability to plants

2008-11-21  The solubility of iron in soils is controlled by Fe(OH) 3 (soil)in well‐oxidized soils, by Fe3(OH)s(ferrosic hydroxide) in moderately oxidized soils, and by FeCO3(siderite) in highly reduced soils. The Fe(III) hydrolysis species Fe(OH) 2 + , and Fe(OH)3° are the major solution species of inorganic Fe, but they are maintained too low to supply available iron to plants.

Iron is considered the key metal in energy transformations needed for syntheses and other life processes of the cells. Consequently, plants regulate iron uptake. Ferrous iron is more soluble and bioavailable to plants than ferric iron.
