- Intervention effect Injection required 31% to 59% less nitrogen than broadcasting to achieve average corn yields.
- Intervention effect Injected UAN cost $12 per acre less than the least-cost broadcast option in 1983.
- Intervention effect Injected UAN cost $8.76 per acre less than the least-cost broadcast option in 1984.
- Intervention effect Injected UAN cost $9.63 per acre less than the least-cost broadcast option in 1985.
- Intervention effect Injected anhydrous ammonia reduced cost relative to the least-cost broadcast option in 1983.
- Intervention effect Injected anhydrous ammonia reduced cost relative to the least-cost broadcast option in 1984.
- Intervention effect Injected anhydrous ammonia reduced cost relative to the least-cost broadcast option in 1985.
- Recommendation Injection could cut nitrogen use by at least 30% while reducing fertilizer and application costs by as much as 50%.
- Intervention effect Injecting urea, UAN, or AA reduced required nitrogen rates by 43% to 59% compared with surface applying urea, UAN, or UUP.
- Intervention effect Compared with surface AN, injected urea, UAN, or AA reduced nitrogen rates by 31% to 43%.
- Intervention effect Injection could reduce nitrogen use without reducing corn yield.
- Observation Fertilizer was the major component of nitrogen application cost.
- Intervention effect Injecting UAN lowered total nitrogen application costs by $9 to $12 per acre versus the least-cost broadcast option.
- Recommendation Injection may increase profits or reduce losses at specified corn yields.
