- Intervention effect Urea increased tobacco yield by 26% relative to NaNO 3 after excess rain.
- Intervention effect Urea increased tobacco grade index by 20% relative to NaNO 3 after excess rain.
- Intervention effect In a dry year, urea reduced tobacco yield by 7% relative to NaNO 3.
- Intervention effect In a dry year, grade indices were similar under urea and NaNO 3.
- Observation Nitrification took 4 to 6 weeks depending on year and location.
- Intervention effect Terr‐O‐Cide 30 reduced nitrification at 2 and 4 weeks relative to nonfumigated soil.
- Intervention effect Telone C‐17 reduced nitrification at 2 and 4 weeks relative to nonfumigated soil.
- Observation Leaf chloride rose until week six and then abruptly fell.
- Observation Leaf chloride reached 3.5% at six weeks under urea with Telone C‐17.
- Observation Cured leaves contained under 0.5% chloride at harvest regardless of treatment.
