Which statement about soil texture is true?

Soil texture refers to the relative proportions of sand, silt, and clay in the soil. It is an essential characteristic that influences water retention, drainage, aeration, and nutrient availability in soil. The assertion that soil texture cannot be changed is accurate because the proportions of these particles are largely determined by the geological makeup of the soil and its formation processes over time. While certain practices can improve soil structure and enhance its overall health, such as adding organic matter, they do not alter the inherent texture, which is a more permanent characteristic.

Soil texture is not something that can be easily modified through cultivation, and while practices may affect soil fertility and health, they do not fundamentally change the proportion of sand, silt, and clay in the long term. Additionally, although water and nutrients are integral components of soil health, soil texture itself specifically refers to the physical composition of soil particles rather than these components. Lastly, soil texture and soil structure are related but distinct aspects of soil; soil structure refers to the arrangement of soil particles, which can be influenced by various agricultural practices, whereas texture remains constant without significant geological changes.
