اقرأ أكثرMolybdenum is present in soils at amounts high enough (0.2-6.0 mg Kg − 1) to support its needs in plants where it appears as one of the scarcest transition elements (He et al., 2005, Kaiser et al., 2005). Plants take up Mo as the anion molybdate (MoO 4 2 −), which is the major soluble form present in soils (Gupta, 1997).

اقرأ أكثرMolybdenum is a trace, but essential mineral found that occurs naturally in many foods, including beans, lentils, leafy greens, nuts, and organ meats. However, the amount found in plant-based foods depends on the molybdenum content of the soil they were grown in.
اقرأ أكثرMolybdenum. Molybdenum is a plant micronutrient.Molybdenum is only required in very small amounts but it is important for nitrogen metabolism; without molybdenum, plants may be able to take up nitrogen but if it's in the form of a nitrate (NO 3 ‑) they can't process it and use it for it's intended purpose (to make amino acids and proteins for instance).

اقرأ أكثرMolybdenum deficiency symptoms in most plants are associated with a build-up of nitrate in the affected plant part. This is a result of poor nitrate reductase activity. Symptoms include: premature germination of maize grain. In legumes, inhibition of N 2 fixation may lead to pale, yellowing, nitrogen-deficient plants.

اقرأ أكثرDeficiency of molybdenum is rare in human body. The amount of this mineral present in plants varies greatly, depending on the soil. A relatively higher amount is present in plants which are grown on neutral or alkaline soils with a high content of organic matter, and a lower amount in those grown on acid, sandy soils.
