Laterite soil's key traits are:
1. Found in areas with significant heat and substantial precipitation.
2. Created by leaching, where rain removes nutrients, leading to poor fertility.
3. Contains little humus because warm, humid climates speed up organic matter breakdown.
Alternative soil types are unsuitable:
- Arid soil: Occurs in dry environments, not areas with heavy rainfall.
- Yellow soil: Commonly found in forested zones, not formed by leaching.
- Black soil: Distinguished by high fertility and association with cotton farming.
