Because of the scarcity of suitable carbon and energy sources for these organisms, their contribution to global nitrogen fixation rates is generally considered minor. However, a recent study in ...

The major transformations of nitrogen are nitrogen fixation, nitrification, denitrification, anammox, and ammonification (Figure 1). The transformation of nitrogen into its many oxidation states ...

61, No. 4 (2016), pp. 1406-1423 (18 pages) Nitrogen (N) transformations and fluxes at the sediment-water interface (SWI) were measured in Missisquoi Bay, Lake Champlain, to clarify the role of N in ...

Plants need nitrogen to grow, but they can’t just grab it from the air like we do with oxygen. If the soil doesn’t have enough, farmers have to add fertilizers—an expensive and environmentally tricky ...

Nitrogen fixation by soybean decreases exponentially as N application rate increases, such that application of 45 lb/ac N can lead to a 40% or greater reduction in N fixation over the maximum ...

Coale’s proteomic studies revealed that UCYN-A acquired its proteins from B. bigelowii for essential functions like amino acid and pyrimidine biosynthesis and for nitrogen fixation. “Seeing flavodoxin ...

Still, we have to start somewhere, and this work shows that nitrogen fixation for corn has potential,” Connor Sible, study co-author and research assistant professor at the University of ...

Barron's graduate research examined interactions between plants, soils and the atmosphere. In particular, he focused on the patterns and controls of nitrogen fixation in Panamanian tropical ...
