On nitrogen fixation and preferential remineralization of phosphorus
Regional and global nitrogen fixation rates are often estimated from geochemical tracers related to N* (=NO3-16PO4). However the patterns of this tracer reflect the influence of numerous processes including nitrogen fixation, denitrification, remineralization of organic matter, atmospheric depositio...
