The chemistry of iron in soils and its availability to plants

2008-11-21  Abstract. 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.

Review on iron and its importance for human health

Biochemistry and physiology. In contrast to zinc, iron is an abundant element on earth[2,9] and is a biologically essential component of every living organism.[10,11] However, despite its geologic abundance, iron is often a growth limiting factor in the environment.[] This apparent paradox is due to the fact that in contact with oxygen iron forms oxides, which are highly insoluble, and thus is ...
