Soil physical properties | Soils | Soil and water | Farm ...

Soil is made of varying amounts of silt, sand and clay. The proportion of these components determines if a soil is a sand, loam or clay or any combination of these. Soil texture has a number of implications for management because it effects the ability of the soil to hold water and its ability to withstand cultivation and compaction.

Soil texture is the relative proportions of sand, silt, or clay in a soil. The soil textural class is a grouping of soils based upon these relative proportions. Soils with the finest texture are called clay soils, while soils with the coarsest texture are called sands.

Soils - Part 2: Physical Properties of Soil and Soil Water

Soil acts as a sponge to take up and retain water. Movement of water into soil is called infiltration, and the downward movement of water within the soil is called percolation, permeability or hydraulic conductivity.Pore space in soil is the conduit that allows water to infiltrate and percolate.

There are 12 classes of soil texture. For example, if most particles are large and coarse the soil is called a sand. It looks and feels sandy. A silt soil is dominated by medium-sized particles and feels like flour. Small-sized soil particles primarily make up a clay soil which feels slippery or greasy when wet.
