Which statement defines soil texture?

Which statement defines soil texture?

• A. The relative proportion of sand, silt, and clay
• B. Organic matter content
• C. The soil pH level
• D. Color

Answer: (A)

Understanding soil texture means looking at the size of the particles that make up the soil. Texture is defined by the relative proportions of sand, silt, and clay. Those proportions determine how the soil feels and how it behaves: sandy soils are gritty and drain quickly; clayey soils are sticky and hold water and nutrients more tightly; loams have a balanced mix that tends to support good structure and plant growth. Organic matter content, pH, and color relate to other soil properties—fertility and structure, acidity/alkalinity, and mineral/organic content appearance—but they do not define texture. So the statement that best defines soil texture is the one describing the relative amounts of sand, silt, and clay.
