Nitrogen deposition is considered a leading determining driver in the species composition changes. Inputs of N to ecosystems have been more than doubled as a result of anthropogenic activities and a further increase of up to 70% is predicted for oxidised N deposition by 2050 from 1990s levels, while reduced N is predicted to rise by up to 133% over the same period. Reduced and oxidised atmospheric N deposition is responsible for various biogeochemical processes, contributing to nutritional balance of terrestrial ecosystems and acid deposition. Atmospheric N deposition mainly comprises of reduced N, resulting largely from agricultural sources, and oxidised form mostly from stationary combustion sources and traffic activities.
As a better simulation of natural deposition processes, small & frequent N additions may result in greater plant growth and proportional increases with greater retention of N within the system. The main aim of this study was to investigate the response of heathland plant community to continued N addition in different forms (reduced & oxidised) with varying applicat ... 전체 초록 보기
