Soil Texture vs. Soil Structure: What's the Difference?
Edited by Janet White || By Harlon Moss || Published on January 6, 2024
Soil texture refers to the proportion of sand, silt, and clay in soil, determining its feel and particle size, while soil structure describes the arrangement of soil particles into aggregates, influencing soil porosity and stability.
Key Differences
Soil texture is about the relative composition of particles of different sizes (sand, silt, clay) in soil, affecting its feel and workability. Soil structure, on the other hand, refers to how these particles are arranged together, impacting the soil's physical properties.
The texture of soil is determined by the proportions of sand, silt, and clay, influencing water retention and drainage. The structure of soil is shaped by the way particles clump, crumb, or bind together, affecting aeration and root penetration.
Soil texture is classified into various types like loamy, sandy, or clayey based on particle size distribution. Soil structure is categorized by the shape of its aggregates, such as granular, blocky, or platy, reflecting the way soil holds together.
The texture of soil plays a key role in nutrient retention, ease of cultivation, and moisture capacity. Soil structure affects erosion resistance, water infiltration, and the ability of plants to establish and grow.
While soil texture is a relatively fixed characteristic, soil structure can be improved through practices like organic matter addition and avoiding compaction, enhancing soil health and productivity.
