Hierarchical grouping and arrangement of soil particles
researchgate.net
- Soil structure refers to the hierarchical grouping and arrangement of soil particles (sand, silt, clay, organic and inorganic particles) into porous compounds forming aggregates which can vary in size and shape from small clusters through to large blocks (Dexter, 1988; Lal, 1991; Kay and Angers, 2001).

Soil structure is the shape in which soil particles group together and form aggregates. A soil aggregate, or conglomerate of sand, silt, clay, and sometimes organic material, may be a variety of different shapes.
Soil chemistry involves the study of the chemical composition, chemical properties and chemical reactions involving soil solids (organic matter and inorganic minerals), liquids (soil water), gases (soil air), including interactions with plants and soil organisms.
Secondary particles called aggregates or peds formed by the arrangement or grouping of primary particles (sand, clay, slit and organic matter) is defined as soil structure. Formation of soil structure. The process of soil formation occurs through physio-chemical process characterized by aggregate formation, flocculation and swelling, shrinking ...
Key concepts. Soil structure refers to the manner in which these individual soil particles are grouped together to form clusters of particles called aggregates. This is determined by the types of soil formation, parent material, and texture. Soil structure can be influenced by a wide variety of biota as well as management methods by humans.
Abstract. Soil structure and soil organic matter (SOM) have an interactive relationship and mediate all soil processes at all spatial and temporal scales. Soil structure and SOM can be degraded through land use, tillage, compaction, and climate change mechanisms.
Jul 9, 2021 · Plant roots. Roots give off a range of compounds (including sugars and gel-like substances called mucigel), into the soil. These substances help bind soil minerals and feed soil microbes. They also help drive soil aggregation.
Oct 29, 2019 · Soil chemistry is the branch of soil science that deals with the chemical composition, chemical properties, and chemical reactions of soils. Soils are heterogeneous mixtures of air, water, inorganic and organic solids, and microorganisms (both plant and animal in nature).
