Understanding Soil Texture and Structure

    Soil texture may be determined in one of two ways. The percentages of sand, silt, and clay may be tested in the lab. Once tested, the textural class of the soil can be determined by referring to the textural triangle. Soils with different amounts of sand, silt, and clay are given different names.

    Soil structure is how the particles are organized. Unorganized particles create poor soil structure, like a heavy clay soil which has poor drainage and poor air porosity. When organic material is added to a clay soil, the clay particles clump together in much larger particles.

    The Properties of Sandy Soils - Living The Bump

    Sandy soils have a light texture and loose structure, which cause them to drain quickly and not hold water well. This can lead to low fertility, but with the addition of some compost, manure or leaf mold, sandy soil can grow a satisfactory

    Soil structure is often confused with soil texture, both of which affect the soil's drainage and aeration capabilities. Well-structured soils, as in the image above, are usually crumbly and friable and have plenty of pore space to allow water and air movement and healthy root development.

    Introduction to Soils: Soil Quality - Penn State Extension

    Soil texture. Soils are usually made up of a mix of the three particle sizes. Sand particles are relatively large, clay particles are very tiny in comparison to sand, and silt particles are medium-sized. Clay and silt particles hold more water and plant nutrients along their surfaces than sand particles.
