The soil erodibility factor in the Universal soil-loss equation (USLE) relates primarily to the soil's infiltration capacity and structural stability.

Indicate whether the statement is true or false

Question 2

The Revised Universal Soil-Loss Equation (RUSLE) is more site-specific, more accurate in predicting soil loss, and more quickly compares alternative procedures than does USLE.

Indicate whether the statement is true or false

Question 3

Slope length is generally of greater significance in determining erosion rate than is steepness of slope.

Indicate whether the statement is true or false

Question 4

The ill effects of acidity in subsoils can be ameliorated by adding gypsum (CaSO4-2H2O) to the soil surface. Which of the following most likely helps account for this effect?

A) Gypsum stimulates root growth in the surface soil horizons.
B) Sulfate ions from the gypsum react with H ions in the subsoil to form H2SO4.
C) Calcium from the gypsum replaces hydrogen from colloids in the subsoil thereby increasing the soil pH.
D) Gypsum dissolves and leaches downward, increasing the Ca/Al ratio in the soil solution in subsoil layers.
E) The gypsum replaces hydrogen from colloids which moves down the profile and decreases the pH of the subsoil layers.
