Which of the following is NOT a soil property?

Permeability refers to the ability of soil to transmit water and air, which is a function of the soil's structure and texture but not a distinct soil property in and of itself. Instead, it is more accurately described as a characteristic resulting from the interplay of soil properties like texture, composition, and fertility.

Texture involves the size distribution of soil particles, which affects water and nutrient retention. Composition refers to the specific minerals and organic matter present in the soil, influencing its fertility and biological activity. Fertility is a measure of the soil's ability to provide essential nutrients to plants. Each of these is considered a primary property of soil, whereas permeability is more of a functional aspect that arises as a result of these properties.
