TLDR
The acetylene reduction assay was used to determine nitrogenase activity in a waterlogged soil–straw system and found that Nitrogenase activity was related to the number of nitrogen-fixing Clostridia.Abstract:

Crop residue management for nutrient cycling and improving soil productivity in rice-based cropping systems in the tropics
TL;DR: In this paper, the intelligent management and utilization of crop residues is essential for the improvement of soil quality and crop productivity under rice-based cropping systems of the tropics, where the major issue is adapting drills to sow into loose residues.

Turnover of microbial tissue in soil under field conditions
TL;DR: The microbial population of a Brown Chernozemic soil was labelled in situ by adding 14C-glucose and 15NH415NO3 to the plow layer.

Nitrogen Fixation by Members of the Tribe Klebsielleae
M. C. Mahl,M. C. Mahl,P. W. Wilson,P. W. Wilson,M. A. Fife,M. A. Fife,W. H. Ewing,W. H. Ewing +7 more
TL;DR: Strains of species of the tribe Klebsielleae were tested for nitrogen fixation and it was concluded that these facultative anaerobic, gram-negative, nitrogen-fixing rods should be placed in the genus Klebsiella pneumoniae.

The effect of organic amendment, water content, and oxygen on the incorporation of 15N2 by some agricultural and forest soils
TL;DR: Thirty samples of nine soil profiles were variously treated and incubated in aerobic and in anaerobic 15N-labelled atmospheres in the laboratory for the addition of glucose to agricultural soils to study the phytochemical properties of glucose.

Nitrogen fixation in submerged soilsand-energy material media and the aerobic-anaerobic interface
F. R. Magdoff,D. R. Bouldin +1 more
TL;DR: In this paper, the authors studied nitrogen fixation in the aerobic-anaerobic interfacial area in flooded, cellulose enriched media and the utilization of the products of anaerobic decomposition of cellulose by nitrogenfixing organisms when these products are brought under aerobic conditions by processes such as diffusion, mixing, and drying.
