Denitrification is a critical process regulating the removal of bio-available nitrogen (N) from natural and human-altered systems. While it has been extensively studied in terrestrial, freshwater and marine systems, the communication between denitrification scientists working on these individual systems has been limited.

PBL studies on denitrification

In one PBL study a summary was made of data on denitrification measurements. A data set consisting of denitrification measurements was complied from peer-reviewed literature (Hofstra and Bouwman, 2005).

The PBL global model for soil and groundwater denitrification (Van Drecht et al., 2003; Bouwman et al., 2005b) has been used in a recent synthesis paper on denitrification (Seitzinger et al., 2006).
