NutraTender 5-5-10 Foliar Fertilizer with Micronutrients, 1 Gallon
This foliar fertilizer stands out for its balanced 5-5-10 NPK ratio combined with essential micronutrients, including molybdenum. Its primary strength lies in quick absorption through leaves, making it ideal for growers seeking immediate nutrient boost during critical growth phases. Compared with chemical sources, NutraTender provides a broader nutrient profile, reducing the need for multiple products. However, its effectiveness hinges on proper dilution, and multiple applications might be necessary to sustain nutrient levels over large areas. It’s especially suited for farmers managing several acres who want an easy-to-apply, fast-acting solution with micronutrients for overall plant health.
Pros:- Balanced nutrient formula promotes overall plant health
- Rapid absorption through foliar application
- Contains essential micronutrients including molybdenum
- Suitable for various plant types
Cons:- Requires proper dilution for effective coverage
- Multiple applications may be needed for sustained results
Best for: Growers needing rapid nutrient delivery and broad coverage
Not ideal for: Growers seeking precise molybdenum control or working with small-scale or research applications
- NPK Ratio:5-5-10
- Volume:1 Gallon
- Micronutrients:Boron, Copper, Iron, Manganese, Molybdenum, Zinc
- Coverage:Up to 2 acres
- Application Method:Foliar
- Suitable For:Multiple plants and broad coverage
Our verdict“An excellent choice for growers who prioritize quick action and wide coverage, with the tradeoff of needing multiple applications for long-term control.”
Sodium Molybdate Na2MoO4*2H2O, >99% Pure – 1 Pound
This high-purity sodium molybdate offers over 99% molybdenum content, making it ideal for precise adjustments in fertilizer mixes or research. It’s suitable for those who want to control molybdenum levels meticulously or incorporate it into custom fertilizer formulations. Compared with foliar options, sodium molybdate demands careful handling due to its chemical nature, and it’s not designed for direct foliar application. Its main limitations are the lack of application instructions specific to agriculture and restrictions in California, where it cannot be sold as a fertilizer. This makes it more appropriate for experienced users or researchers with safety protocols in place.
Pros:- High purity (>99%) ensures reliable, consistent results
- Versatile uses including research and custom fertilizer blending
- Sealed resealable bag guarantees safety and freshness
Cons:- Not available for sale as a fertilizer in California
- Requires handling with care due to chemical nature
- Limited direct application guidance for agricultural use
Best for: Researchers, advanced growers, or formulators needing precise molybdenum levels
Not ideal for: Growers seeking a ready-to-use foliar spray or quick application without formulation work
- Brand:Alpha Chemicals
- Model Number:1NaMo
- Purity:>99%
- Unit Count:16 Ounce
- Application Type:Research, formulation
- Availability:Not sold as fertilizer in California
Our verdict“Best suited for users who need exact molybdenum control or are developing custom fertilizer mixes, with the tradeoff of requiring handling expertise.”
How We Picked
Our selections focus on products that deliver reliable molybdenum availability for legumes, considering absorption method, purity, ease of use, and practicality for different farm sizes or research needs. We prioritized products with clear specifications, positive user feedback, and distinct roles—either as quick-acting foliar feeds or precise chemical sources.

Factors to Consider When Choosing Molybdenum Fertilizer For Legumes
Selecting the right molybdenum fertilizer for legumes involves considering application method, scale, and your need for precision. Foliar fertilizers like NutraTender are excellent for quick absorption and broad coverage but require multiple applications for sustained levels. Chemical sources such as sodium molybdate are better for precise control and formulation but demand careful handling and understanding of chemical safety. Matching your crop management style with these factors will help optimize nitrogen fixation in legumes while minimizing waste and overuse.
Application Method and Scale
If you prefer ease of use and rapid results, a foliar fertilizer like NutraTender makes sense, especially for large-scale applications where quick absorption is needed. For small-scale use, research, or custom fertilizer blending, chemical sources like sodium molybdate provide control over molybdenum content. Consider your farm size, labor capacity, and whether you need immediate or long-term nutrient adjustments.
Purity and Precision
High-purity chemicals such as sodium molybdate are ideal for those who want to fine-tune molybdenum levels or incorporate it into advanced fertilizer mixes. Conversely, foliar fertilizers deliver a balanced nutrient profile with less effort, but may require multiple applications. Think about whether you need precision or convenience, and choose accordingly.
Handling and Safety
Foliar fertilizers are generally safer and easier to apply, although they still demand proper dilution. Chemical molybdenum sources need careful handling, protective gear, and proper storage. If you’re not familiar with chemical safety protocols, a foliar product might be the safer choice, while professionals or researchers may prefer the control offered by chemical forms.
Frequently Asked Questions
Can I use sodium molybdate directly on my legumes?
While sodium molybdate can be used as a supplement to increase molybdenum levels, it is not typically applied directly as a foliar spray. Instead, it is usually incorporated into fertilizer mixes or used in soil applications by experienced growers or researchers. Proper handling and dosing are essential to avoid over-application, which can harm plants or lead to environmental issues.
What are the main differences between foliar fertilizers and chemical molybdenum sources?
Foliar fertilizers like NutraTender are designed for quick absorption through the leaves, providing immediate nutrient boosts across large areas. They are easier to apply but may require multiple treatments for sustained levels. Chemical sources such as sodium molybdate offer precise control over molybdenum content and are suitable for formulation or soil application but need careful handling. Your choice depends on whether you prioritize convenience or precision.
Is molybdenum application necessary for healthy legumes?
Molybdenum is a vital micronutrient for legumes, as it plays a key role in nitrogen fixation. Deficiency can lead to poor growth and reduced yields. Proper supplementation, either via foliar or soil application, ensures optimal plant health and productivity. However, overuse should be avoided, as excess molybdenum can become toxic.
Are there safety concerns with using sodium molybdate?
Yes, sodium molybdate is a chemical that requires careful handling, including protective gear and proper storage. It is not intended for direct application without formulation and should be used in accordance with safety guidelines. Its chemical properties mean it’s best suited for experienced users or professional formulation rather than casual application.
Can I buy sodium molybdate in California as a fertilizer?
No, sodium molybdate is not available for sale as a fertilizer in California due to state regulations. If you need molybdenum supplementation in California, a foliar fertilizer like NutraTender might be a better choice, or you will need to source it from regions without such restrictions. Always check local regulations before purchasing or applying chemical fertilizers or supplements.
Conclusion
For growers seeking quick, broad coverage and ease of application, NutraTender is the better fit, especially for larger farms or those needing rapid results. Those who require precise control over molybdenum levels, either for research or custom formulations, should consider sodium molybdate, keeping in mind the handling precautions. Beginners or small-scale farmers may prefer the foliar approach for its simplicity, while experienced users or formulators will find the chemical source more suitable for detailed nutrient management.
