Molybdenum in the environment. Molybdenum differs from the other micronutrients in soils in that it is less soluble in acid soils and more soluble in alkaline soils, the result being that its availability to plants is sensitive to pH and drainage conditions. Some plants can have up to 500 ppm of the metal when they grow on alkaline soils.

The company's major nickel assets include the Niihama Nickel Refinery (nickel) in Ehime Prefecture, Japan and a 27.5 percent share ownership in the Ambatovy Project in Madagascar.

The Role of Molybdenum in Agricultural Plant Production

Jul 20, 2005· • Background The importance of molybdenum for plant growth is disproportionate with respect to the absolute amounts required by most plants. Apart from Cu, Mo is the least abundant essential micronutrient found in most plant tissues and is often set as the base from which all other nutrients are compared and measured.

Molybdenum - an overview | ScienceDirect Topics

Both molybdenum and nickel in steel increase the carburized case depth. Nickel is more effective than molybdenum in increasing the case depth. The combined effect of molybdenum and nickel is much greater than that of either molybdenum or nickel alone in increasing case depth (Figure 35(a)).
