A ’well structured‘ soil has plenty of living spaces, storage spaces, doorways, and passages (for utilisation by water, gases, nutrients, roots and a vast array of organisms). In turn, soil organisms, such as earthworms, can directly alter the structure of the soil. This is important to retention of plant nutrients (soil fertility) and the retention of charged polutants. Soils also protect plants from the destructive biological, physical, and chemical activities and equally shield them against erosion. The primary soil particles—sand, silt and clay—usually occur grouped together in the form of aggregates. Not all soil minerals are equal. Single particles when assembled appear as larger particles.

Natural aggregates are called peds, whereas clod is an artificially formed soil mass. It is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of wastes, and as a participant in the cycling of elements. Classification. Soil porosity refers to the pores within the soil. Soil structure affects water and air movement in a soil, nutrient availability for plants, root growth, and microorganism activity.
