| Reasons of Sulfur Deficiency |
| Sulfur is a critical component in soil and plant health. Disruptions to this cycle can impact the rate at which plants grow and even the nutritional value of the food they produce. |
| High content of NPK fertilizer |
| Farmers tend to use high content of NPK fertilizersto 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. |
| Large increase in crop yield |
| A lot of sulfur is absorbed from the soil by crops and cannot be supplemented. Over the past 40 years, high content of sulfur-free fertilizers have consumed much more than sulfur, resulting in a lack of sulfur in soil. |
| With continuous stringent environmental protection standards, SO2 emissions from factories continue to decline, and the amount of sulfur deposited cannot meet the needs of a variety of crops. |
