Using indirect methods to constrain symbiotic nitrogen fixation rates: a case study from an Amazonian rain forest

2010-07-01

Abstract excerpt

Human activities have profoundly altered the global nitrogen (N) cycle. Increases in anthropogenic N have had multiple effects on the atmosphere, on terrestrial, freshwater and marine ecosystems, and even on human health. Unfortunately, methodological limitations challenge our ability to directly measure natural N inputs via biological N fixation (BNF)—the largest natural source of new N to ecosystems. This confou...
