Other claims from this paper (9)
- Intervention effect Sulfur rate, source and timing did not affect yield on soils with SOM above 20 g kg −1.
- Intervention effect Sulfur rate, source and timing did not affect protein concentration on high SOM soils.
- Intervention effect Eight kg S ha −1 maximized grain yield on low SOM soils.
- Intervention effect Eight kg S ha −1 maximized protein concentration on low SOM soils.
- Observation Flag leaf sulfur concentration varied among varieties independently of sulfur rate.
- Association Yield responses were likely below 2.8 g S kg −1 flag leaf sulfur.
- Association Tissue N/S ratios related negatively to grain yield.
- Recommendation Sulfur application should target soils with SOM below 20 g kg −1.
- Recommendation Sulfur rate guidelines should not vary by variety.
