Which statement best defines soil texture?

Which statement best defines soil texture?

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

Answer: (B)

Soil texture is about the relative amounts of the three main mineral particle sizes in soil—sand, silt, and clay. This mix determines how coarse or fine the soil feels and how it behaves: sandy soils drain quickly and don’t hold water or nutrients well, while clay-rich soils hold more water and nutrients but can drain slowly and compact easily. The role of texture is different from other soil properties—organic matter content affects structure and fertility, pH tells you how acidic or alkaline the soil is and influences nutrient availability, and color often reflects moisture and organic matter levels. Because texture is defined by the actual balance of sand, silt, and clay, the statement describing their relative proportions provides the best definition of soil texture.
