PHYSICAL PROPERTIES OF THE SOIL 4.1 Texture: Texture refers to the relative proportions of particles of various sizes such as sand, silt and clay in the soil. The proportions of the separates in classes commonly used in describing soils are given in the textural triangle shown in Fig.1.5. In using the diagram, the points corresponding to the percentages of silt and clay present in the soil ...

Soil physical properties: Texture and structure. Note number: AG1061 Published September 2003 Reviewed: September 2006 . 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 ...
