Ocean iron fertilization is an example of a geoengineering technique that involves intentional introduction of iron-rich deposits into oceans, and is aimed to enhance biological productivity of organisms in ocean waters in order to increase carbon dioxide (CO 2) uptake from the atmosphere, possibly resulting in mitigating its global warming effects.
Another cause of concern is the sheer amount of urea needed to capture the same amount of carbon as eq. iron fertilization. The nitrogen to iron ratio in a typical algae cell is 16:0.0001, meaning that for every iron atom added to the ocean a substantial larger amount of carbon is captured compared to adding one atom of nitrogen.

White beans. There’s a reason beans are a go-to for plant-based eaters. One half-cup of white beans offers nearly 3.5 mg of iron, the USDA says, along with 8.7 grams (g) of protein and 5.6 g of ...
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.
[citation needed] Inadequate amounts of boron affect many agricultural crops, legume forage crops most strongly. [citation needed] Boron deficiencies can be detected by analysis of plant material to apply a correction before the obvious symptoms appear, after which it is too late to prevent crop loss. Strawberries deficient in boron will ...
The germ is the embryo of the seed that contains B vitamins and trace minerals. Because the germ has a fat content of 10%, [citation needed] it may reduce shelf-life. [citation needed] Thus, it is separated to ensure longer shelf life of the flour. In contrast to enriched flour, whole wheat flour contains both the bran and the germ.
Even if your plants are actively growing in winter and need fertilizer, don’t apply the fertilizer straight. Instead, dilute the fertilizer with water to ¼ strength before application. Apply ...
Absorption of dietary iron in iron salt form (as in most supplements) varies somewhat according to the body's need for iron, and is usually between 10% and 20% of iron intake. Absorption of iron from animal products, and some plant products, is in the form of heme iron, and is more efficient, allowing absorption of from 15% to 35% of intake.
