In aerobic soils, the oxide, hydroxide, and phosphate forms control the concentration of Fe in solution and its availability to plants. In typical aerated plant production systems of acceptable reaction (pH) of +/- 6.0, the concentrations of ferric (Fe +++) and ferrous Fe ++ iron are on the order of 10 -15 molar (very low concentration).
Seeking to improve biogas plant efficiency and understanding why Ferrous Chloride, Not Ferric Chloride, is the best of the two as a dosing additive within a balanced biogas output-raising product. During a recent exhibition stand enquiry I was making, an expert from Lukeneder helped me understand this point.

M.Sreevalli Abstract A simple, rapid and sensitive spectrophotometric method was developed for the determination of trace amounts of iron using as a chromogenic reagent. The proposed method was based on the reaction of iron with ammonium thiocyanate forming a complex having a maximum absorption at 450 nm.

Ferrous Wear Concentration gives a direct measure of the amount of ferrous wear metals present in a sample. Trending of ferrous concentration reveals changes in the wear mode of the system. A fdMplus monitor provides a means of detecting and measuring ferrous wear debris in lubricating oils, hydraulic oils, and greases regardless of particle size.
Iron is typically provided by a fertilizer and most plants prefer a constant iron application rate of 1 ppm. Plants such as calibrachoa, diaschia, petunia, scaevola, snapdragon, etc. prefer higher iron application rates, so it may be best to supplement with an iron chelate as suggested above.
These species reach a minimum solubility near 10 −10 in the pH range of 7.5–8.5 while plants and microorganism require <10 −6 M Fe in solution Full size image In this context, the present review will focus on the impact of microbes in association with plant roots and Fe minerals on the availability of Fe in soils.

Heme iron is highly bioavailable (15%-35%) and dietary factors have little effect on its absorption, whereas nonheme iron absorption is much lower (2%-20%) and strongly influenced by the presence of other food components. [ 23] On the contrary, the quantity of nonheme iron in the diet is manyfold greater than that of heme-iron in most meals.

An imbalance between the solubility of iron in soil and the demand for iron by the plant are the primary causes of iron chlorosis. Although abundant in most well-aerated soils, the biological activity of iron is low because it primarily forms highly insoluble ferric ...

The goal of the goethite process is to remove the ferrous ion concentration from 10–16 g/L to 0.3–0.8 g/L. Furthermore, to obtain satisfactory goethite precipitate, the ferric ion concentration must remain low ( Ismael & Carvalho, 2003 ). It implies that the goethite process is achieved by slow oxidation.
