| Sulfur deficiency affects the growth of global agriculture |
| Due to the global air pollution control and crop yield increse, sulfur loss and sulfur deficiency in soil is increasingly serious. There is a widespread lack of sulfur in soil around North America, India, China and Europe, which has a tremendous pressure on agricultural production.
|
| Farmers tend to use high content of NPK fertilizers to obtain high yield , and fertilizer manufacturers committed to remove other components of the NPK fertilizers to save the cost of transportation and sales, which made the sulfur from fertilizers is almost completely eliminated. |

¡°If farmers find they need it, I have no doubt that sulfur fertilization will provide a good return. Both your crop and your livestock would suffer without sufficient levels of this nutrient.¡± |
| Dr. Jerry Jung, USDA Pasture Research Laboratory, University Park, PA |
¡°In many areas, you can¡¯t maintain optimum production without sulfur. Without it, your yields will decrease and¡ªif the deficiency gets bad enough, which it will¡ªthe decrease in yield will become severe¡¡± |
| Dr. Fred Koehler, Washington State University

| Global Sulfur Deficiency Overview |
| The U.S. Clean Air Act is impacting crop sulfur requirements.
Today , significant areas of the southern and northwestern United States have sulfur recommendations. |
|
|
| Sulfur deficient area: 30% of arable soil,eq.
about 95 million acres,
and sSulfur deficit in 2010 was 2.0 million tons and will be projected to increase to 2.6 million tons in 2015. |
|
|
| 41% and 36% of soil samples (26810) in 11 states in India are sulfur deficient or potentially deficient.At least 168 million acres, or 40% of India's arable land suffers from varying degrees of S deficiency. |
|
|
| Due to emission controls in the last ten years, sulfur deposition in West Europe has dropped below the requirements of many crops. |
|
|
| Agricultural production recovery driven by strong demand for food and biofuel : soybean , corn and sugarcane. |
