B. As the clay content increases, the amount of plant lignin in the soil increases.
C. As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which increases the rate of decomposition.
D. As the clay content increases, the permeability decreases, which increases the rate of decomposition.
