Other claims from this paper (6)
- Observation The low-lying position was often wetter than summit and sideslope positions in 2005 and 2006.
- Intervention effect Anhydrous ammonia increased corn grain yield over urea in the low-lying position in 2005 and 2006.
- Intervention effect PCU increased corn grain yield over urea in the low-lying position in 2005 and 2006.
- Intervention effect AA increased plant N uptake and NRE relative to urea in the low-lying position in 2005 but not 2006.
- Observation Gross profit differences for PCU and preplant AA versus urea in the low-lying position could range from $50 to $642 per hectare.
- Recommendation Targeted nitrogen fertilizer sources in claypan landscapes may increase corn grain yields and profitability.
