Soil physical properties are those related to the size and arrangement of solid particles, and how the movement of liquids and gases through soils is affected by the particles. Soil mineral particles are derived from the weathering of rocks and minerals. Soil organic matter is the product of microbial decomposition of the remains of plants and animals.

Soil texture refers to a particular soil's distribution of mineral particles within certain size ranges. (Organic matter is removed before soil texture is determined.) Soil texture is an intrinsic property of a soil, which may be influenced by geologic processes such as erosion, but generally does not change appreciably within a human life span or as a result of human activities.
