Fox et al. 2006 define soil texture as the diametrical size of the soil particles. Soils with larger particles are more gravelly whereas those with tiny particles are more claylike. Loam soil refers to a soil type that consists of the different size particles such as sand, clay and silt but does not exhibit any physical characteristic of any of them. Soil texture is important in plant growth because it influences aeration, drainage, water holding capacity and cation exchange capacity. Aeration refers to the spaces found in soil that enable it to hold air. Aeration affects the drainage of a soil as well as its ability to support plant growth. The sizes of the soil particles define the size of the spaces. For instance, gravel soils have large spaces within them, whereas clay soils have small spaces within them.
