Soil Structure

The term soil structure refers to the arrangement and organization of the particles which make up our soil. These particles can be arranged in a loose and haphazard manner, or they can form a distinct, uniformly structured pattern.

Basically, there are three broad categories of soil structure:

• Single Grained
  Single grained particles are those which are totally unattached to each other. They are entirely loose.
• Massive
  When soil is tightly packed, such as in the case of dried clay, it is said to be massive.
• Aggregated
  Aggregated soil is located somewhere between the two extremes. It is an intermediate condition in which the particles are relatively alike and arranged in small clods.

By controlling a soil's pore shape, size, and distribution, soil structure is the major factor in determining a soil's ability to retain and transmit fluids. Thus, it is very important that one knows a specific soil's structure in order to manage it efficiently.
