  1. Wheat Sulfur Trial 2013 University of Arkansas Wilson Industrial

  2. Field 1- 1 WAT (Week after Treatment)

  3. Field 2- 1 WAT

  4. 1 WAT Notes • Field 1 • No noticeable effects of application on plant height or color • No Difference in treated vs. untreated plots • Field 2 • There was a significant difference in plot appearance based on rate and source of S product • All plots receiving AMS were not affected • Plots receiving the 30 lb S/A and 45 lb S/A as ATS were visibly “burned” or yellowed by application

  5. Field 2- 1 WAT These plots received the 30 and 45 lb S/A rate as ATS and were visibly yellow due to application. Similar results were seen in all 4 reps at this site.

  6. Field 1- 7 WAT (Flag leaf emergence)

  7. Field 2- 7 WAT (Flag leaf emergence)

  8. Field 2- 7 WAT (Flag leaf emergence) All plots receiving S looked good. The plot that did not receive S was noticeable deficient.

  9. S Deficiency Symptoms at Field 2

  10. S Deficiency Symptoms at Field 2 S deficient plot in foreground, with S addition plots behind.

  11. 7 WAT Notes • Field 1 • No noticeable difference in plant height or color among treatments receiving S • Some minor S deficiency symptoms appearing in the plots that received no S applications • Field 2 • No noticeable difference in plant height or color among treatments receiving S • Major S deficiency symptoms appearing in the plots that received no S applications

  12. Overall Notes • Early in the season ATS products appeared to burn leaves when applied at rates of 30 and 45 lb S/A • There was no noticeable affect of AMS application at any rate • Wheat grew out of early season symptoms • Both products appear to be adequate at providing S to wheat • Plant samples will be taken 8 WAT to determine S tissue concentration and total S uptake near Early Heading
