Other claims from this paper (7)
- Observation In 16 crop models evaluated for maize heat stress, current parameterizations in most models favor daylight temperature although the algorithm was designed for daily mean temperature.
- Observation Different drought algorithms considerably differed in their patterns of water shortage over the growing season for maize.
- Observation Despite differing water-shortage patterns, the different drought algorithms predicted similar decreases in annual maize yield.
- Observation Model simulations show drought will continue to be the largest threat to rainfed maize and soybean production.
- Observation Spatial patterns of dominant stressors are projected to shift, characterized by increases in concurrent stress.
- Observation The authors indicate that future adaptation strategies will have trade-offs between multiple objectives.
- Method / resource The prototype crop-model and satellite-imagery N sidedress prescription tool for US rainfed maize captures subfield variability of N dynamics and gives reasonable spatially explicit sidedress N recommendations.
