Place soil in hand, remove pebbles, and add water very slowly, until it has the potential to have the consistency of putty. Add more soil or water as needed. a. If the soil does not remain in a ball, circle "sand" 2. If the soil remains in a ball, squeeze the ball between your thumb and forefinger, attempting to make a ribbon of uniform thickness and width pushing up and over your forefinger until it breaks from its own weight. a. If no ribbon is formed, record "loamy sand" 3. If ribbon forms but breaks before it is 2.5 cm, rub the soil between fingers. a. If very gritty, record "sandy loam" b. If very smooth, record "silt loam" c. If neither gritty or smooth, record "loam" 4. If ribbon breaks between 2.5 and 5 cm, rub the soil between fingers. a. If very gritty, record "sandy clay loam" b. If very smooth, record "silty clay loam" c. If neither gritty or smooth, record "clay loam" 5. If ribbon breaks when it is >5 cm, rub the soil between fingers. a. If very gritty, record "sandy clay" b. If very smooth, record "clay" c. If neither gritty or smooth, record "silty clay" HABITAT TYPES: Adapted from Brown et al.
