Categorized under "General"

The top layer of the earth's surface, consisting of rock and mineral particles mixed with organic matter.

Definition as written by jaws:

Soil structure is the way the soil particles are arranged into larger units called peds. A soil with good soil structure has many more channels, or macropores, for the movement of air and water.

Definition as written by IA_Soil_Sci:

Structure, soil. The arrangement of primary soil particles into compound particles or
aggregates. The principal forms of soil structure areó platy (laminated), prismatic
(vertical axis of aggregates longer than horizontal), columnar (prisms with rounded
tops), blocky (angular or subangular), and granular. Structureless soils are either
single grain (each grain by itself, as in dune sand) or massive (the particles
adhering without any regular cleavage, as in many hardpans).
