Plant<\/h3>

The main role of molybdenum is to improve the ability of plants to take up and utilise nitrogen<\/a>, otherwise known as Nitrogen Use Efficiency (NUE).<\/p>

Molybdenum is a component of two enzymes which help convert nitrate to ammonium within the plant, enabling the synthesis of amino acids.<\/p>

It is required for the symbiotic fixation of atmospheric nitrogen<\/a> by Rhizobia bacteria in root nodules of leguminous crops such as beans, peas and clover.<\/p>

Where there is a lack of molybdenum, the conversion of nitrogen<\/a> to protein within the plant is likely to be poor.<\/p>

Animal<\/h3>

In animals, molybdenum is a component of several enzymes which are involved in electron transfer.<\/p>

The level of molybdenum in an animals blood should be kept below 3ppm to avoid inducing copper<\/a> deficiency.<\/p> <\/div>\n <\/div>\n\n <\/div>\n\n

Soil<\/h3>

Molybdenum is available for plant uptake in its ionic form (MoO4<\/sub>2-<\/sup>). Its negative charge means it is unable to bind to negatively charged clay particles, therefore it is vulnerable to leaching losses.<\/p>

Soils high in molybdenum are likely to induce copper<\/a> deficiency.<\/p> <\/div>\n <\/div>\n\n <\/div>\n\n

Deficiency <\/i><\/span><\/i><\/span><\/h5> <\/div>\n\n

Molybdenum deficient plants present with poor grain set due to reduced pollen viability.\u00a0<\/p>

In maize, deficiency signs include reduced tasseling, flowering and pollen formation.\u00a0<\/p>

Molybdenum deficiency in cauliflower results in poor leaf development.\u00a0<\/p>

Due to its role in improving nitrogen efficacy, molybdenum deficiency plants can also present with nitrogen deficiency symptoms including yellowing of the older leaves.\u00a0<\/p>

Where is the risk of deficiency highest?<\/h5>
