- Soil structure and texture are the physical properties that influence soil retention, drainage system, and aeration capabilities. It also defines the movement of air, water and ions within the soil, which affects other factors like seed germination, root growth, and erosion processes.
Soil texture refers to the proportions of sand (2.0 – 0.05 mm in diameter), silt (0.05 – 0.002 mm), and clay (less than 0.002 mm). The relative proportions determine the textural class. Soil texture influences nearly every aspect of soil use and management.

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. Structure is important because it allows critical areas of open space, vital for water to move, roots to grow, and soil organisms. Consid...
Columnar
Columnar are a special type of structure created when sodium impacts a prismatic structure. A ‘muffin top’ or ‘popcorn’ looking appearance on the top of a prism develops from sodium dispersing particles. These are agronomically challenging soils to manage. Both water and roots will likely have problems moving through this soil easily.
Massive or Single grained
These units of ‘non structure’ indicates there has been limited changes to this soil since deposition. In glacial till materials, a large piece will likely break between the points of pressure applied, rather than falling apart on pre-determined lines. A midwestern soil at perhaps five feet of depth may not have developed structure because this takes something acting on it. Roots, freeze-thaw, wetting-drying and other factors are less active here, slowing down changes. For single-grained soil...
Since plant growth tends to increase soil structure, more plant growth tends to lead to a better structure. In prairie ecosystems, a strong granular structure is expected. Tillage can have negative impacts on soil structure, particularly when done in poor (generally too wet) conditions. Consider the building construction of the earlier example in t...

Soil texture refers to the weight proportion of different sizes of soil particles in a given soil sample. It is described using a textural class or classification system based on the particle size distribution.
Soil texture is defined as the relative proportions of each class (clay, silt and sand). Sands give the material strength while clays bind it together and silt fulfils a less clear intermediate function. It is important to get the right texture for soil-cement block production.
Oct 5, 2024 · Soil is composed of four main components: minerals, organic matter, water, and air. These components are arranged in different layers, or horizons, which make up the soil profile. The top layer of soil is called the topsoil, which is rich in organic matter and supports the majority of plant life.
