Blocky structural units are common to find in a B horizon or cultivated A horizon. They can be grouped by either angular blocky having sharp angles likely found in higher-clay soils, or subangular blocky, the more rounded corners.

26 cze 2021 · Soil structure is the arrangement of the individual soil particles into aggregates which are separated by surfaces of weakness. The structural aggregates, which are called peds, comprise several types depending on their shape: granular, blocky, prismatic, columnar, and platy.
Blocky structures are commonly found in subsoils where clay content is higher, helping to improve the stability and resilience of the soil. The formation of blocky structure is influenced by organic matter content, as well as biological activity from organisms like earthworms and fungi.
29 lip 2015 · From a morphological stance, the Natural Resource Conservation Service (NRCS) defines soil as: “a natural body comprised of solids (minerals and organic matter), liquid, and gases that occurs on the land surface, occupies space, and is characterized by one or both of the following: horizons, or layers, that are distinguishable from the initial m...
Soil structure is described using the following three characteristics. 1) Degree of development. Soil structure can be: Strongly developed – natural aggregates are clearly evident in undisturbed soil and the soil breaks apart easily into discrete, natural aggregates with litle force.
