Molybdenum is an important micronutrient for plant growth.

Molybdenum is required for the function of enzymes involved in redox processes. Liming is well known to increase Mo availability and is the most effective treatment to correct/prevent the deficiency.

In wheat, symptoms of Molybdenum deficiencies depend on the nitrogen status of the plant. Under high N, molybdenum deficient plants are much paler than those with adequate Molybdenum . Yellow striping may also occur longitudinally on middle-aged leaves. New growth is largely unaffected, whilst there may be some necrosis to older leaves.

The total demand of Molybdenum for oilseed rape is not very high because of the low Molybdenum -content in the plant. Therefore, Mo deficiency symptoms are not frequently observed under field conditions. Under severe Molybdenum deficiency, only the midrib continues to grow and the leaf lamina is not formed. Marginal chlorosis and necrosis occur on older leaves which have a high content of nitrate, and leaves may become pale and limp.

Crop Nutrition

Plants need around 12 essential mineral nutrients to grow: Nitrogen (N), Phosphorous (P), Potassium (K), Magnesium (Mg), Sulphur (S), Calcium (Ca), Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu), Boron (B) and Molybdenum (Mo).

Grain nutrient analysis

Analysing grain for all 12 nutrients can be an effective tool to improve nutrient management, providing information on crop nutrient status and nutrient offtakes.  It can indicate whether your crops are getting hold of the nutrients they need, or whether you can save on future fertiliser use.
