Sulfur 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.
• NutraSul 90 is registered as an approved material with Washington State Department of Agriculture Organic Food Program.

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.

• 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.
• Supreme is registered as an approved material with Washington State Department of Agriculture Organic Food Program.

Recommendations:

• Supreme provides a 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 Supreme and Ammonium Sulfate is very effective).
• However, if Supreme is applied regularly as part of a balanced fertility program, Sulfur levels can be maintained without Sulfate.

Supreme 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 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.
	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

12-0-0-50S 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.
