Iron fertilization is the intentional introduction of iron-containing compounds (like iron sulfate) to iron-poor areas of the ocean surface to stimulate phytoplankton production. This is intended to enhance biological productivity and/or accelerate carbon dioxide (CO 2 ) sequestration from the atmosphere.
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.

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.
Nitrogen fertilizer being applied to growing corn in a contoured, no-tilled field in Iowa.. Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off-site transport ...
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
It is selectively taken up by plants, so there are a variety of possible roles in plant metabolism. [44] There is limited medical use. [11] Inhibits iron uptake and metabolism in a variety of plants and bacteria. [44] germanium: 32: 2a: Some plants will take it up, but it has no known metabolic role. [11] Some salts are deadly to some bacteria ...
Of course, the more Fertilizer you use, the faster you'll master crops, so make sure to build your Fertilizer Bin and start putting it to good use as fast as you can. Play FarmVille 2 on Zynga.com ...
Because biodigestors can be used as fertilizer, it reduces the amount of industrial fertilizers that are needed to sustain the yields of the farm. Another technique used is aquaculture integration, which combines fish farming with agricultural farming, using the wastes from animals and crops and diverting them towards the fish farms to be used ...
