Other claims from this paper (7)
- Intervention effect The 30-cm WTC treatment had the greatest drainage nitrate loss, 715 µg N column ‐1.
- Intervention effect The 60-cm WTC treatment reduced nitrate loss by 54% relative to 30 cm.
- Association Nitrate drainage loss tracked drainage volume in the order 30 > 60 > 80 cm WTC.
- Intervention effect After first simulated rain, 30-cm WTC increased N2O production 12.7-fold versus 60 and 80 cm.
- Intervention effect Water stress from 80-cm WTC limited crop growth and nitrogen uptake.
- Intervention effect Water stress from 80-cm WTC limited leaching and N2O emissions.
- Observation As much as 28% of added N remained in soil after 80-cm WTC corn harvest.
