- Observation Surface applied fertilizers lost less than 6% of N through ammonia volatilization.
- Intervention effect Urea plus SSP produced higher soil Olsen P than DAP at every placement.
- Intervention effect Surface broadcasting lowered plant yield versus incorporation.
- Intervention effect DAP and urea plus SSP gave equally high N uptake when incorporated or deep placed.
- Intervention effect Surface applied DAP gave lower N uptake than urea plus SSP.
- Association The two fertilizer sources showed the same relationship of P uptake to soil Olsen P at each placement.
- Intervention effect Urea plus SSP produced higher plant yields than DAP at all placements.
