Will intensive forest practices impact water quality?
Date:1/7/2008

ith intensive forest practices using BMPs did not dramatically affect runoff concentrations and losses of nutrients from these watersheds. Nutrient export was a small fraction of what was applied, and most of the loss occurred within the first few storms after treatment.

Forest fertilization usually has a small, short-lived impact on nutrient losses. This is in part due to the relative infrequency of fertilization (1-2 applications per 25-30 year stand rotation) and lower inherent fertility of most forest soils. In addition, streamside buffers help stabilize stream channels and prevent direct application of fertilizers to streams, thus reducing potential water quality impacts. Finally, rapid herbaceous and woody vegetation regrowth and subsequent nutrient uptake in the warm, humid Southeast reduced the amount of nutrients available for movement offsite.
