Sulfur Fertilizer

NutraSul 90 Sulphur Fertilizer

MSDS NutraSul90 Info Sheet NutraSul 90 Sulphur Fertilizer NutraSul 90 Sulphur Fertilizer

Product description

  • Split-pea shaped pastille
  • Two kinds of Bentonite that are combined to total 10% of the product analysis: One clay is very high swelling and slow hydrating, and the other swells less and hydrates very quickly – a combination that results in superior degradability.

Guaranteed Analysis:

 

Typical Properties:

Sulfur 90.0% from elemental sulfur   Color Medium Green Pastilles

Bentonite

10.0% total Bentonite clay from 2 sources   Angle of Repose 29 degrees
      Particle Size Size guide #260, diameter 2.6 - 3.0 mm, height 1.4 - 1.5 mm
      Bulk Density 75 pounds per cubic foot or 1201 kg per cubic meter
      Breakage Characteristics Less than 0.25% is -42 mesh at truck loading. See research on safety & handling or impact tests.
      Packaging Shipped in bulk with trucks or rail cars. Mini-bulk totes of 2700 lbs (1225 kg). Plastic bags of 50 lbs each (22.68 kg), palletized and wrapped (54 bags/pallet).

 

Recommendations:

  • NutraSul 90 provides a natural slow release of Sulfate throughout the season.
  • Application rate is based on agronomic recommendations from soil tests and should also consider crop removal rates of Sulfur.
  • With Sulfur deficiencies in soil, soluble Sulfate must be applied to high Sulfur-requirement crops such as oil seeds (a blend of NutraSul 90 and Ammonium Sulfate is very effective).
  • However, if NutraSul 90 is applied regularly as part of a balanced fertility program, Sulfur levels can be maintained without Sulfate.

 Product Description:

  • Split-pea shaped pastille
  • Two kinds of bentonite make up 15% of the product analysis for better dispersion within the pastille. One clay is very high swelling and slow hydrating, and the other swells less and hydrates very quickly – a combination that results in superior degradability.

Liter Sphere apparatusSupreme 85:  Safety Benefit of Lower Dust Fire Hazard

2010 testing of Minimum Explosible Concentration using international testing standards shows Supreme 85 is safer to use:

    1. 75 micron sized dust was dispersed in test chamber
    2. Attempts were made to ignite the dust
    3. Different concentrations are tested to determine minimum  concentration of dust  for ignition

RESULTS:

  1. Minimum Concentration for ignition:  Supreme 85:  65 g/m3 vs. 55 g/m3 for NutraSul 90
  2. 18.2% more Supreme 85 dust is required for ignition, making this a safer product

Conclusion:
Supreme 85 has 50% more Bentonite clay than 0-0-0-90 sulfurs, and the result is that it is a harder prill.  With normal handling, Supreme 85 generates less dust from attrition, and what dust that is present is less apt to ignite than a comparable concentration of 0-0-0-90 dust.

Impact Test for Dust

 

Impact tests simulate wear on pastilles from fertilizer handling.  The lower dust in Supreme 85 impact tests demonstrates higher durability than 0-0-0-90s (~35% improvement).   Lower dust improves product safety and comfort in handling.

Bulk Resistivity of Sulfur-Bentonite Products

Resistivity measures the tendency to build up electrostatic charges in airborne dust near stored Sulfur.  With 15% Bentonite, less dust is produced but what airborne dust there is, is an excellent conductor and electrostatic charges bleed off readily.  Supreme has 10 times lower Resistivity – a considerably safer choice than 0-0-0-90s.



Sulfur ▪ Ammonium Sulfate Blends

Sulphur Ammonium Sulfate Blends MSDS Keg 12-0-0-50S Sulphur Ammonium Sulfate Blends MSDS Keg 9-0-0-60S

Product Description:

  • Provide the benefits of immediately available Sulfate and time released Elemental Sulfur – ideal for crops requiring Sulfate immediately (e.g. Canola), and a sulfur supply throughout the growing season
  • The Sulfate is provided from a quality prilled Ammonium Sulfate (20.5–0–0–24); the degradable portion of the blend is from NutraSul 90
  • Considered an excellent product for the introduction of Degradable Elemental Sulfur to the fertilizer unit, especially when there is limited bin space.
  • This can be the dealer's best choice for a high analysis premium product that is cost effective and easy for the dealer or grower to handle.
