Abstract

Describes the effects of trenching in a Quercus ilex forest in the Montseny mountains (NE Spain) in terms of nitrogen dynamics and movement in the soil. Three or 4 months after trenching, soil concentrations of NH4-N and NO3-N, rates of net N mineralization, and nitrification had all greatly increased in trenched plots relative to control plots at both 0-5 cm and 5-20 cm depths. Nitrate concentrations in the soil solution at 40 cm depth were also markedly increased. This quick and large response reveals a high potential for nitrate losses following disturbance in this ecosystem. -from Authors
