Soil Texture Triangle Quiz

Study Notes

Soil Types and Compositions

Sandy Clay Loam: Comprised of 30% clay, 50% sand, and 20% silt; offers good drainage while holding some nutrients.
Silt Loam: Contains 10% clay, 30% sand, and 60% silt; ideal for agriculture due to its nutrient retention and moisture-holding capacity.
Loam: Balanced mix of 20% clay, 40% sand, and 40% silt; often considered the ideal soil for gardening and farming due to its fertility.
Silt Loam: Another variation with 10% clay, 20% sand, and 70% silt; also provides excellent moisture retention.
Clay Loam: Made up of 35% clay, 40% sand, and 35% silt; retains moisture well but with better drainage than pure clay.
Clay: Contains 50% clay, 25% sand, and 25% silt; characterized by its heavy texture and low drainage capacity.
Sandy Loam: Composed of 15% clay, 70% sand, and 15% silt; provides good drainage and air circulation, beneficial for root development.
Silt Loam: Another version with 15% clay, 15% sand, and 70% silt; high fertility makes it suitable for crop production.
Clay Loam: An additional mixture with 33% clay, 33% sand, and 33% silt; balances retention and drainage effectively.
Clay: Another variant, with 70% clay, 20% sand, and 10% silt; very dense and can create compacted layers in the soil profile.

Soil Texture Interpretation

To Silt: Determine the direction of the line drawn from clay towards silt when interpreting soil texture.
To Sand: Identify the line's route from silt towards sand for accurate soil classification.
To Clay: Establish the path from sand back towards clay for proper understanding of soil texture dynamics.
