Which term refers to a distinct layer of soil with specific properties?

The term that refers to a distinct layer of soil with specific properties is "Soil Horizon." Each soil horizon represents a specific depth within the soil profile, characterized by unique physical, chemical, and biological properties. These layers can vary greatly in color, texture, structure, and organic matter content, reflecting the soil's history and the processes that have shaped it.

Understanding soil horizons is crucial for various applications, including agriculture, environmental management, and land-use planning. By analyzing the characteristics of different horizons, one can infer soil health, fertility, and suitability for different types of plant growth or development practices.

The other terms do not specifically denote a distinct layer of soil. "Soil Type" generally categorizes soils based on their texture and composition rather than the layered structure. "Soil Aggregate" refers to clusters of soil particles that form a stable structure, impacting water retention and aeration, but does not denote a layer. "Soil Layer" is a more generic term that could encompass any layer within the soil but lacks the specificity and defined characteristics associated with a soil horizon. Thus, "Soil Horizon" is the most accurate term for this context.
