Relationships of Nitrous Oxide Emissions to Fertilizer Nitrogen Recovery Efficiencies in Rain-fed and Irrigated Corn Production Systems: Data Review

IPNI-2015-USA-4RN27

Justification: Nitrous oxide (N2O) emissions from corn production systems are a large societal concern because so much of the N fertilizer applied to crop production in the United States is applied to corn, and because agriculture alone accounts for the majority of N2O emissions from all sources. The IPCC (2006) has estimated that an average of approximately 1. Read more

Interpretive Summary

2015

Relationships between cumulative nitrous oxide (N2O) emissions and N recovery efficiency (NRE) during corn production remain largely unknown, perhaps because N2O emission and NRE are seldom measured and/or reported for the same experiments. Appropriate regression models were applied to published N2O emission data (treatment mean N2O; n = 338) collected at sites where corn whole-plant N uptake at maturity (published and unpublished) was also determined.
