Sulfur is one of the main elements plants need to grow. Sulfur is essential in several growth functions such as Nitrogen metabolism, enzyme activity, and protein and oil synthesis.

Yellowing of leaves is the main Sulfur deficiency symptom. However, unlike Nitrogen and Iron deficiency which causes old leaves to turn yellow; Sulfur deficiency would cause young leaves to turn yellow. Also, prolonged flowering and pale colored flowers could be caused by Sulfur deficiency.

Elemental Sulfur is the most concentrated type of Sulfur from 90% to 99% (Greenway Biotech, Inc. Sulfur contains 99% Sulfur). However, Elemental Sulfur can't be used by plants and it needs to break down in soil by microorganisms to Sulfate form.

Sulfate is found only in combination with other fertilizers. Most common types of Sulfate fertilizers are:

• Ammonium Sulfate
• Ferrous Sulfate
• Potassium Sulfate

Sulfate is readily available for plants and is highly water soluble.

It really depends on what kind of diseases in the soil. However, it would work to protect against diseases that are caused by Sulfur deficiency or diseases such as tuber rot, which is caused by fungus and Fusarium found in soil.

Our Sulfur powder contains 99% Sulfur (Active Ingredient) and it is 99.9% pure. This might be a little confusing because the numbers are so close but for example, our Urea contains 46% Nitrogen and it is 99.9% pure. Percentage of purity and active ingredient are 2 different numbers.

Yes, Sulfur powder and dust are flammable. When Sulfur burns, it produces Sulfur Dioxide (SO2). Also, Sulfur dust suspended in air ignites easily, and can cause an explosion in confined areas. Sulfur could be ignited in different ways such as flames, sparks, static electricity, etc.
