Other claims from this paper (7)
- Intervention effect Increasing nitrogen fertilizer and manure application increased corn yields in 1993.
- Intervention effect Increasing nitrogen fertilizer and manure application increased corn N uptake.
- Association Grain yields correlated strongly with corn tissue total nitrogen.
- Observation Two kg of manure nitrogen were equivalent to 1 kg of urea nitrogen for first-year plant uptake and yield response.
- Observation Nitrate movement in the top 75 cm was not significant up to 225 kg ha1 manure nitrogen.
- Recommendation Precise manure application can match commercial nitrogen fertilizer for corn yield response.
- Recommendation Precise manure application can pose little threat to groundwater quality.
