A 2010 study of iron fertilization in an oceanic high-nitrate, low-chlorophyll environment, however, found that fertilized Pseudo-nitzschia diatom spp., which are generally nontoxic in the open ocean, began producing toxic levels of domoic acid. Even short-lived blooms containing such toxins could have detrimental effects on marine food webs. [138]
Roughly 5 grams of iron are present in the human body and is the most abundant trace metal. [1] It is absorbed in the intestine as heme or non-heme iron depending on the food source. Heme iron is derived from the digestion of hemoproteins in meat. [4] Non-heme iron is mainly derived from plants and exist as iron(II) or iron(III) ions. [4]
If soil iron concentration is high, in spite of this it can become unavailable for absorption if soil pH is higher than 6.5. [1] Excess of elements such as manganese in the soil can interfere with plant iron uptake triggering iron deficiency. [2] Iron is needed to produce chlorophyll, hence its deficiency causes chlorosis.
It's true that red meat is an excellent source of iron, but there are plenty of vegetarian sources of iron — think leafy green vegetables, beets, black beans and lentils, says Cunningham.

Human iron homeostasis is regulated at two different levels. Systemic iron levels are balanced by the controlled absorption of dietary iron by enterocytes, the cells that line the interior of the intestines, and the uncontrolled loss of iron from epithelial sloughing, sweat, injuries and blood loss. In addition, systemic iron is continuously ...
Researchers found that those who consumed the highest amount of heme iron, which is found in red meat and animal products, had a 26% higher risk of developing type 2 diabetes.
Plant nutrition is a difficult subject to understand completely, partially because of the variation between different plants and even between different species or individuals of a given clone. Elements present at low levels may cause deficiency symptoms, and toxicity is possible at levels that are too high.
