  • Soils, Plant Nutrition and Nutrient Management | MU Extension

    Molybdenum. Molybdenum is taken up by plants as molybdate ions (MoO 4-). Molybdenum is an essential micronutrient that enables plants to make use of nitrogen. Without molybdenum, plants cannot transform nitrate nitrogen to amino acids and legumes cannot fix atmospheric nitrogen. Molybdenum deficiency can occur in acidic, sandy soils.
