| Sulphur fertilizer can increase crop yields and quality and result in significant economic returns to producers. |
| Both the yield and quality of crops grown on sulphur-deficient soils are reduced unless sulphur is included in the fertilizer treatment. Sulphur fertilizer can increase crop yields and quality and result in significant economic returns to producers. TSI conducted numerous field experiments in India which demonstrated the positive impact on yield. |
| The following table summarizes these research findings: |
