Abstract Molybdenum accumulation by forage plants was affected by its concentration in a neutral soil, by plant species, and by depth to water table. Accumulation by Medicago sativa L. and Festuca arundinacea Schreb. increased 5.2 and 3.5 ppm, respectively, for each kg/ha Mo added to the soil. Molybdenum accumulation varied significantly among the 25 forages tested. Legumes generally accumulated more Mo than grasses did. Forage from Lotus sp. had the highest concentration of Mo, and Trifolium sp. ranked next in accumulation of this element. Twelve grasses and Carex sp. are classified as low Mo accumulators. Depth to water table was associated with Mo accumulation during 2 of 3 years. Forage grown where the water table was near the soil surface contained more Mo than where depth to water table was greater.
