TLDR
The solubility of Fe in soils is largely controlled by Fe oxides; ferrihydrite, amorphous ferric hydroxide, and soil-Fe are generally believed to exert the major control.Abstract:
The solubility of Fe in soils is largely controlled by Fe oxides; ferrihydrite, amorphous ferric hydroxide, and soil-Fe are generally believed to exert the major control. Fe(III) hydrolysis species constitute the major Fe species in solution. Other inorganic Fe complexes are present, but their concentrations are much less than the hydrolysis species. Organic complexes of Fe including those of organic acids like citrate, oxalate, and malate contribute slightly to increased Fe solubility in acid soils, but not in alkaline soils.read more

Agronomic approaches for improving the micronutrient density in edible portions of field crops
TL;DR: In this article, a review of literature indicates that fertilization with inorganic and organic forms of micronutrients has a potential to increase their concentrations in grain, and that the most effective fertilization could be via soil (for Zn and, to some extent, Cu), foliarly (for Fe) and by adding fertilizers to the irrigation water (for iodine).

A review on the potentiality of Rare Earth Elements to trace pedogenetic processes
C. Laveuf,Sophie Cornu +1 more
TL;DR: In this article, the authors consider the use of REEs to trace pedogenetic processes, in order to quantify the respective contribution of successive processes on pedogenesis, and conclude that REEs, much more than other trace elements, can interestingly trace the considered processes that are encountered in a large diversity of non-polluted soils arising from diverse parent materials.

The rhizosphere and plant nutrition: a quantitative approach
TL;DR: Despite extensive experimental evidence of root-mediated changes to the physical, chemical and biological status of rhizosphere soil, the quantitative significance of these changes for mineral nutrition has not been assessed.

The Iron Oxides
R. M. Cornell,U. Schwertmann +1 more
TL;DR: The food-quality iron oxides are primarily distinguished from technical grades by their comparatively low levels of contamination by other metals; this is achieved by the selection and control of the source of the iron or by the extent of chemical purification during the manufacturing process as discussed by the authors.
