    The increased aerial input of NHx to forests leads to a large supply of nitrogen to trees and - depending on the rate of nitrification - to a change in the amrnonium/nitrate ratio in the soil. In this study the effect of these changes in nitrogen availability on growth and funccioning of Douglas-fir, and in the rhizosphere pH along its roots was investigated.... Zie: Summary
