What are soil aggregates? - Soils Matter, Get the Scoop!

15-07-2022 · Aggregate formation is a complex process. Soil aggregates are formed through physical, chemical and biological activity below ground. They are even influenced by human factors, like tilling, walking on the surface, or even how you fertilize your garden. Formation of aggregates begins with finer soil primary particles binding together.

Soil Aggregates - an overview | ScienceDirect Topics

Aggregate size, as noted above, is an important parameter, dictating their potential to be mobilized by the wind (Chepil, 1957; Chatenet et al., 1996; Zobeck, 1991b). Rough surfaces with a combination of soil aggregate sizes may result in smaller aggregates becoming trapped between larger ones, thus minimizing wind erosion potential (Bisal, 1973).
