How is soil structure defined?

Soil structure is defined as the arrangement of soil particles into aggregates or peds, which plays a crucial role in determining various soil properties and behaviors. This arrangement affects water infiltration, root penetration, aeration, and overall soil health. Well-structured soil typically has aggregates that create spaces for air and water movement, promoting a healthier environment for plant roots and soil organisms. The way particles cling together can significantly influence soil functions, such as nutrient availability and organic matter decomposition. Understanding soil structure is vital for effective land management, agricultural practices, and environmental conservation because it directly impacts soil fertility and ecosystem sustainability.
