Other claims from this paper (13)
- Association The viable planting period generally decreases with increasing latitude.
- Observation Most staple spring planted crops need very similar accumulated heat to mature when average corn variety is considered.
- Recommendation The authors recommend crop-specific planting temperature as the base for temperature summation.
- Method / resource Using a 6°C base for cotton at Abilene would count roughly three months of heat before planting is possible.
- Observation Spring wheat seeding begins at a lower mean temperature than other major spring crops.
- Observation Spring wheat seeding begins at 37°F in the Dakotas and Nebraska.
- Observation Spring oats seeding begins at a normal daily temperature of −13°F.
- Observation Early potato planting generally begins at 45°F.
- Observation Corn planting begins at 55°F.
- Observation Cotton planting generally begins at about 62°F.
- Observation The available thermal constant for corn is about 1,600°F.
- Observation The available thermal constant for cotton is about 2,000°F.
- Association Lowering cotton planting temperature to the corn threshold would materially enlarge the cotton production area.
