Title
Effects of Gypsum Application Rate and Frequency on Corn Response to Nitrogen

Other claims from this paper (8)
- Intervention effect Corn yield response to gypsum applications was inconsistent.
- Intervention effect A positive corn yield response to gypsum application occurred only in 2017 at the Northwest site.
- Recommendation The best management strategy may be to apply lower gypsum rates either annually or biannually.
- Intervention effect Gypsum did not improve corn response to N at either study site.
- Intervention effect Gypsum applications significantly increased tissue, grain and extractable soil S concentrations.
- Association S concentrations decreased as gypsum application frequency decreased.
- Intervention effect Frequent gypsum applications at lower rates were better than a one-time large application.
- Recommendation Where S deficiency may occur, gypsum at a low frequency would increase S availability.
