The Residence Times of Nutrients in the Soils of Boreal

The residence times of nutrients in the soils of boreal forests are influenced the most by the

A) rate of litter input, which is increased by severe weather changes.
B) rate of litter input, which is decreased by increased moisture in the soil.
C) decomposition rates, which are slowed by the low soil temperatures and by secondary compounds.
D) decomposition rates, which are increased by the anoxic soil conditions caused by the low soil temperatures.
