Soil Structure is the arrangement of soil particles and their stability in the soil.

Soil structure refers to how soil particles are organized and aggregated into larger units or clusters, which can affect the soil's physical and chemical properties. Soil structure is determined by a variety of factors, including the size and shape of soil particles, the amount of organic matter present, and the presence of biological activity such as earthworms or soil fungi.

The stability of soil structure is important for plant growth and soil health. A stable soil structure allows for adequate pore space for air and water movement, which can improve root growth and nutrient uptake. Additionally, stable soil structure can reduce soil erosion and improve soil water retention.

Soil structure can be affected by a variety of factors, including compaction, excessive tillage, and lack of organic matter. Soil compaction can occur from heavy machinery or foot traffic, which can reduce the pore space in the soil and limit air and water movement. Excessive tillage can also break apart soil structure and lead to soil compaction. Incorporating organic matter into the soil can improve soil structure by providing a source of carbon for soil microorganisms, which can create pore spaces and improve soil stability.
