What are the 5 types of soil?
The 5 Different Types Of Soil
- Sandy Soil. Sandy soil is light, warm, and dry with a low nutrient count.
- Clay Soil. Clay weighs more than sand, making it a heavy soil that benefits from high nutrients.
- Peat Soil. Peat soil is very rarely found in natural gardens.
- Silt Soil.
- Loamy Soil.
