Particles in a soil mass are arranged geometrically to form the soil structure. It determines how soil behaves.

Important Soil Structure Types

The particle size and way of formation are the key determinants of the soil structure types, but other factors also have a role. The various structural kinds are as follows:

1. Single-grained architecture

Sand and gravel are the two primary materials that include particles in this form. The figure depicts this structure's loosest and densest packaging. The densest state has a void ratio of 0.35, whereas the loosest state is 0.91.

2. Honeycomb architecture

Fine sands and silts contain this kind of structure. This kind of structure collapses when used for building, and significant deformation occurs as a result of vibrations and shocks.

3. A Flocculated Soil Composition

It is primarily present in clays and is created when distinct particles are attracted to one another in a net attractive way. According to the figure, this form of structure is oriented edge to face. It has a high permeability, low compressibility, and very high shear strength.

4. Distributed Architecture

It can be found in remolded clays. As seen in the illustration, this form of structure is oriented face to face. Although the compressibility strength is high, the shear strength and permeability are very weak. When there is a net repulsive force, this type of structure forms.

5. Compound soil structure 

There are various types of particles in this soil formation.

How the Soil's Structure Degrades

The following factors can weaken or destroy soil structure:

  • Compaction Cultivation
  • Vegetation removal
  • excessive dirt handling and movement screening
  • Too much sodium

Clay particles reject one another when wet due to a high sodium-to-calcium and magnesium ratio, which causes aggregates to disperse and the process of organic compost soil structure development to be reversible. The distributed clay and small organic particles plug up residual soil pores in soils with too much salt, making the soil nearly impervious to water (Donahue et al 1983). Irrigation and road salting might result in sodium levels that are too high.

Utilizing Microorganisms to Enhance Soil Health

To enhance plant performance, Holganix Bio 800+ infuses soil with more than 800 different types of soil microorganisms. How does that affect you?

That implies that you improve soil and root health while enhancing the advantages of a better soil structure for your particular soil type. This translates to increased crop productivity, enhanced golf course playability, and less need for pesticides and fertilizers on lawns.
