- Intervention effect N alone increased 2020 sorghum yield by 60 bu/a.
- Intervention effect N and P together increased 2020 sorghum yield by up to 83 bu/a.
- Intervention effect Over ten years, N and P fertilization increased sorghum yield by up to 82 bu/a.
- Intervention effect 160 lb/a N with P produced the highest yield in 2020.
- Intervention effect Potassium application had no effect on sorghum yield during the study.
- Observation Ten-year average grain N content reached about 0.7 lb/bu.
- Observation Ten-year average grain P content reached 0.15 lb/bu.
- Observation Ten-year average grain K content reached 0.19 lb/bu.
- Observation At the highest fertilizer rates, grain recovered 69% of P fertilizer.
- Observation At the highest fertilizer rates, grain recovered 40% of K fertilizer.
- Intervention effect N fertilization increased soil organic matter.
- Intervention effect N fertilization decreased soil pH.
- Intervention effect P fertilization tended to maintain or increase soil test P levels.
