Alabama
Representative warm-season temperature is 25°C, inside the 22–29°C optimum. Annual rainfall is 1,331 mm, inside the 700–4,000 mm absolute rainfall range.

Commercial crop requirements
Growing Ginger: climate, soil and water requirements
Ginger has an optimum temperature range of 22–29°C within an absolute 13–35°C envelope.
Its profile calls for 1,200 mm of seasonal water and an optimum soil pH of 6–7.
How to read the figures
Profile figures come from the source cited at the foot of this page. Regional figures are representative reference values, not coordinate-level measurements.
Climate envelope
Use the optimum band for screening normal crop development and the absolute range as an outer tolerance boundary. Accumulated heat still depends on the local planting window and daily temperatures.
| Requirement | Profile value |
|---|---|
| Optimum temperature | 22–29°C |
| Absolute temperature range | 13–35°C |
| Heat to maturity | 1,800 growing degree days above a 13°C base |
| Photoperiod | Short-day response; 12-hour critical daylength |
| Vernalisation | Not required |
| Established-plant cold-hardiness limit | 0°C |
Soil and pH
| Requirement | Profile value |
|---|---|
| Optimum pH | 6–7 |
| Tolerated pH range | 5–7.5 |
| Waterlogging tolerance | Intolerant |
An intolerant rating means drainage is a screening constraint. Check infiltration, perched-water risk, field outlets and the duration of saturation before committing land.
Water
| Requirement | Profile value |
|---|---|
| Seasonal water requirement | 1,200 mm |
| Optimum rainfall band | 1,400–3,000 mm |
| Absolute rainfall range | 700–4,000 mm |
Irrigation becomes necessary when effective in-season rainfall is below the 1,200 mm seasonal requirement. Convert that gap into a field schedule only after accounting for soil water storage, application efficiency and local rainfall timing.
Nitrogen demand
The profile assigns Ginger nitrogen-demand category 3, which translates to moderate demand. It is a relative category, not a fertiliser rate.
Set the field program from soil and tissue evidence, expected removals, prior-crop effects and local nutrient rules.
Crop-level reference profile
| Requirement | Profile value |
|---|---|
| Average yield | 10.5 t/ha reference average |
| Growing period | About 145 days from spring growth to harvest in one season, derived from 1,800 growing degree days above 13°C at a 25.5°C mean season temperature. Modelled from the crop profile. |
Where it grows well
These examples pass a stated temperature or rainfall comparison using representative regional values. Regional screening, not parcel-level.

Research basis
These papers support the qualitative interpretation of the crop profile. No paper-derived figure is used on this page; the named crop and region fields remain the only sources of displayed agronomic numbers.
- Growth, yield and rhizome quality of ginger (Zingiber officinale Rosc.) under varying shade and moisture regimes
High water requirement and heat sensitivity during rhizome enlargement support high irrigation needs and afternoon heat moderation.
Taking this to a field decision
This profile cannot set planting depth, row spacing, seeding rate, cultivar choice, fertiliser rate, harvest timing, irrigation schedule or drainage design. Those decisions depend on cultivar, local practice and field conditions.
Use a coordinate-level audit, local field evidence and commercial terms before a land or lending decision.
