Good soil structure is important for determining how soil particles bond to each other, how porous soils are, and how they respond to compaction.
Soils in the human landscape are often disturbed leading to drainage problems and low levels of organic matter.
Soil structure is classified according to the size and shape of the peds. Peds are the smallest unit of soil structure that holds together in a clump. Soils range from very fine such as sand to massive and hard to break apart.
