Which statement accurately defines soil texture and soil structure and explains why loam soils are generally favorable for gardening?

• A. Texture and structure are the same concept.
• B. Texture refers to organic matter; structure to soil temperature.
• C. Texture is the mineral component proportions; structure is the arrangement of soil particles; loam has balanced sand, silt, and clay with good water retention and drainage.
• D. Texture is about soil color; structure relates to drainage.

Answer: (C)

Soil texture and soil structure describe different aspects of the soil. Texture is about the mineral particles present, specifically the proportions of sand, silt, and clay that make up the soil. Structure is about how those particles clump together into aggregates, creating pore spaces that govern water movement, drainage, and root penetration. Loam soils are favorable because they strike a balance among the particle sizes, forming stable aggregates that provide both adequate water retention and good drainage, along with enough air for roots and soil life. This combination supports nutrient availability and healthy plant growth. The other statements mix up concepts—texture isn’t defined by organic matter or color, and structure isn’t about temperature—so they don’t fit.
