Silt soil is a type of soil that contains medium-sized particles, which provide better water retention than sandy soils. It has moderate water-holding capacity and drainage characteristics. During drought, silty soils can retain moisture for longer periods compared to sandy soils.
Silt is detritus (fragments of weathered and eroded rock) with properties intermediate between sand and clay. A more precise definition of silt used by geologists is that it is detrital particles with sizes between 1/256 and 1/16 mm (about 4 to 63 microns). [2]
SILT. ween clay and sand. The silt particles have limited ability to retain plant nutrients, or to release them to the soil soluti. n for plant uptake. Silt tends to have a spherical shape, giving a high silt soil a soapy or slippery feeling when rubbed be-tween the fingers when wet and is more difficult to form into .
Silt is a medium size particle falling between .002 and .05 mm in size. The largest particle is sand with diameters between .05 for fine sand to 2.0 mm for very coarse sand. Soils that are dominated by clay are called fine textured soils while those dominated by larger particles are referred to as coarse textured soils.
In this article we discuss on properties, characteristics, size, shape and constituents of least sized soil types namely sand, silt, clay and loam. 1. Sand. It is most extensively used construction material. It consists of particles of rock and hard minerals, such as silicon dioxide.
Silt is a solid, dust -like sediment that water, ice, and wind transport and deposit. Silt is made up of rock and mineral particles that are larger than clay but smaller than sand. Individual silt particles are so small that they are difficult to see.
All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil’s properties – its texture, structure, porosity, chemistry and colour.
