Grow coconuts. Coconut is suitable for growing in low altitude areas.

Suitable soil is alluvial seabed and riverbank alluvial soil (sand soil, sandy loam soil, gravel soil, etc.)

Coconut requires a groundwater level of 1.0-2.5m (poorly drained clay and swampy soil are not suitable for planting).

The soil fertility requirement is rich in potassium fertilizer, nitrogen and phosphorus fertilizers are also needed.

The soil pH value is required to be 5.2-8.3, of which 7.0 is the most suitable.
