What does soil stratification refer to?

Soil stratification refers specifically to the layering of soil types and textures in a specific order. This concept is critical in understanding how different soil layers can impact plant growth, water drainage, and nutrient availability. The variation in textures—from sandy to clayey—can significantly influence the physical and chemical properties of the soil, affecting its overall fertility and the types of vegetation that can thrive in that environment. Recognizing soil stratification allows for better land use planning, agriculture practices, and conservation strategies, as it provides insight into how to manage different layers for optimal productivity and environmental health.

For instance, the uppermost layer, often rich in organic matter, may support a diverse range of plants, while deeper layers may have varying drainage capabilities or nutrient content, which can either compete with or support root systems. Understanding this layering is essential for soil management and the effective use of different soil types.
