Nutrient deficiencies / RHS Gardening
Molybdenum deficiency is normally seen in cauliflowers and brassicas, particularly when growing in insufficiently alkaline soil. Cause: Molybdenum is required for a variety of plant growth processes, but is needed only in tiny quantities. Soil shortages of molybdenum are rare, but it can be less available to plant roots in acid conditions.

Molybdenum metabolism in plants and crosstalk to iron
Introduction. Molybdenum is a transition metal, which occurs in the lithosphere at an average abundance of 1.2 mg kg-1 and represents one of the scarcest trace elements in biological systems (Kaiser et al., 2005).In the soil, molybdenum exists predominantly in the form of the oxyanion molybdate, which serves as an essential micronutrient in all …
What is a Molybdenum Deficiency in plants? | ICL UK
Molybdenum (Mo) deficiency is a condition where plants do not receive an adequate supply of molybdenum, which is an essential trace element required for their growth and development. Although required by the plant in very small amounts, any shortage will lead to very pronounced deficiency symptoms on the leaves.
