plants are very sensitive to molybdenum deficiency but excess can lead to decreasing of b iomass, seed yield and deteriorates the quality of pr oduction .
Since the most important function of molybdenum in plant metabolism is in the NO 3 (nitrate) reduction, molybdenum deficiency resembles nitrogen deficiency. Plants suffering from molybdenum deficiency are restricted in growth; their leaves become pale and eventually wither.
Molybdenum is an essential micronutrient which means it is essential for plant growth and development, but is required in very small quantities. Although Mo requirements vary among crops, Mo leaf concentrations (on a dry matter basis ) in the range 0.22.0 mg kg 1 are adequate for most crops.
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).
Molybdenum (MoO4 ) Functions. Molybdenum is essential for many plant functions. It functions in converting nitrates (NO3 ) into amino acids within the plant. It is essential to the symbiotic nitrogen fixing bacteria in legumes. It is essential to the conversion of inorganic P into organic forms in the plant.
Molybdenum in plants and soils Molybdenum is essential to plant growth as a component of the enzymes nitrate reductase and nitrogenase. Legumes need more molybdenum than other crops, such as grass or corn, because the symbiotic bacteria living in the root nodules of legumes require molybdenum for the fixation of atmospheric nitrogen.
Oct 05, 20180183;32;Function of molybdenum. Molybdenum is an essential component in two enzymes that convert nitrate into nitrite (a toxic form of nitrogen) and then into ammonia before it is used to synthesize amino acids within the plant. It also needed by symbiotic nitrogen fixing bacteria in legumes to fix atmospheric nitrogen.
