Soil Texture and Structure – Soils Laboratory Manual
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. Many of the physical and chemical properties … See more

A soil scientist often needs to estimate soil texture while in the field or when laboratory data on the amounts of sand, silt, and clay are not available. With practice, you can learn to estimate texture by simply feeling or manipulating a moist sample. To learn this technique, consider a simplified and generalized version of the textural triangle ...

Particle size analysis is based on the principle that different size particles fall through a fluid at different rates. A particle falling in a fluid is subjected to 3 forces: gravity, buoyancy, and friction (Figure 7.5). The gravity and buoyancy forces are constant, but the frictional force increases as the velocity increases (like the drag force ... See more
Soil texture - Wikipedia
Soil texture is a classification instrument used both in the field and laboratory to determine soil classes based on their physical texture. Soil texture can be determined using qualitative methods such as texture by feel, and quantitative methods such as the hydrometer method based on Stokes' law. Soil texture has agricultural applications such as determining crop suitability and to predict the response of the soil to environmental and management conditions such as drought or
