Abstract

Experimentally induced incipient N saturation in a paired-catchment experiment at the Bear Brook Watershed in Maine. Nitrate flux from the treated catchment has increased from 200 to >500 equiv ha-1 yr-1. Seasonal patterns in stream NO3 - concentrations have been fundamentally altered by the treatment, with NO3 - loss now occurring nearly all year from the experimental watershed. Results suggest that N saturation, soil acidification, and altered N cycling in forested watersheds may be induced at lower rates of N deposition than previously believed. -from Authors
