agricultural productivity; air quality; climate change; corn; fertilizer rates; models; nitrogen; nitrogen fertilizers; social benefit; social welfare; society; uncertainty; Minnesota
Abstract:
... Effective management of nitrogen (N) fertilizer is central to enhancing agricultural productivity, while improving water and air quality and mitigating climate change. Quantifying “socially optimal” rates of N fertilizer (i.e. maximizing net benefits to society while minimizing social costs) is a key component of any regulatory or incentive program designed to better manage N application. Here, we ...

actin; corn; crops; developmental stages; enzyme-linked immunosorbent assay; field experimentation; genotype; glyceraldehyde-3-phosphate dehydrogenase; growing season; hybrids; leaves; models; peptide elongation factors; plant tissues; safety assessment; transgenic plants; India
Abstract:
... Genetically modified (GM) crops undergo large scale multi-location field trials to characterize agronomics, composition, and the concentration of newly expressed protein(s) [herein referred to as transgenic protein(s)]. The concentration of transgenic proteins in different plant tissues and across the developmental stages of the plant is considered in the safety assessment of GM crops. Reference o ...

carbon dioxide; carbon sequestration; corn; crop yield; cropland; cropping systems; deaeration; energy costs; fossil fuels; global warming; greenhouse gas emissions; greenhouse gases; groundwater; intensive farming; irrigation; land use change; nitrous oxide; no-tillage; rainfed farming; risk; soil; soil organic carbon; soybeans; water resources; Midwestern United States
Abstract:
... Groundwater irrigation of cropland is expanding worldwide with poorly known implications for climate change. This study compares experimental measurements of the net global warming impact of a rainfed versus a groundwater‐irrigated corn (maize)–soybean–wheat, no‐till cropping system in the Midwest US, the region that produces the majority of U.S. corn and soybean. Irrigation significantly increase ...
