Sodium molybdate dihydrate supplies concentrated molybdenum (Mo) for precision fertilizer blending and hydroponic nutrient formulation. This 20 lb size provides 39.5% molybdenum in a reclosable 2-gallon pail for growers preparing their own nutrient solutions.

Product Details

• Guaranteed analysis: 39.5% molybdenum (Mo).
• Derived from sodium molybdate dihydrate.
• Net weight: 20 lb.
• Packaging: reclosable 2-gallon plastic pail.
• A single-nutrient component, not a complete fertilizer.

Molybdenum supports enzymes involved in nitrate utilization and is needed by the root-nodule bacteria responsible for nitrogen fixation in legumes. Plants require only very small amounts. Account for molybdenum already present in your water and other fertilizers before adding a separate source.

Nutrient-Solution Mixing Example

The product label lists 0.05–0.2 ppm elemental molybdenum as a common nutrient-solution concentration range. This is a formulation reference, not a universal recommendation for every crop.

1. Dissolve 0.75 g of sodium molybdate in 1 US gallon of water to prepare a dilute concentrate.
2. Add 5 mL of this concentrate per US gallon of working nutrient solution and mix thoroughly.

At the 39.5% guaranteed analysis, this example adds approximately 0.10 ppm molybdenum, in addition to any Mo already supplied. Use an accurate scale and graduated measuring device. Do not confuse the concentrate recipe with the final application rate.

Important Use Guidance

Use according to recommendations from a certified crop advisor, agronomist, university extension publication, or your approved nutrient management plan. This example is not a foliar, seed-treatment, or field-application rate. Read the label and safety data sheet before handling.

NOT FOR USE ON FORAGE CROPS FOR RUMINANT ANIMALS. Excess molybdenum in forage can interfere with copper nutrition in grazing animals.
