ROTATION EFFECT OF PULSE CROPS ON NITROGEN FIXATION AND CARBON INPUT TO SOIL
… can reduce nitrogen (N) requirements via biological N2 fixation (BNF) and provide greater carbon (C) inputs to soil than non-pulse crops in rotation. The goal of this research was to estimate the BNF and C input to soil by various pulse crops (chickpea, lentil and field pea) grown in …

Use of 15N2 for direct measurement of free-living N2 fixation
The use of 15N-labeled dinitrogen (15N2) affords the only direct means of measuring free-living nitrogen fixation (FLNF); however, progress in utilizing this approach has been impeded by methodological limitations and a lack of standardization regarding soil sampling, storage, and incubation. Such …

Nitrogen isotopes in chlorophyll and the origin of Eastern Mediterranean sapropels
… a significant source of new nitrogen from biological N2-fixation. It is suggested that attempts to reconstruct the nitrogen isotopic composition of marine organic matter in the past by measuring the δ15N of whole sediments may be subject to misinterpretation due to the alteration of …
