Vesicular arbuscular mycorrhizal spore populations in various Saskatchewan soils and the effect of inoculation with Glomus mosseae on faba bean growth in greenhouse and field trials
Author(s):Kucey, R. M. N.; Paul, Eldor A.
Date Issued:1983-01
Format:born digital; articles
The numbers of vesicular arbuscular mycorrhizal spores in various Saskatchewan soils, and the effect of Glomus mosseae inoculation on the growth of faba beans (Vicia faba) were studied. The size of the mycorrhizal spore ...
Control of the protein content of Thatcher wheat by nitrogen fertilization and moisture stress
Author(s):Hutcheon, W. L.; Paul, Eldor A.
Date Issued:1966-06
Format:born digital; articles
Experiments are reported in which it was shown that the protein content of spring wheat, grown in the growth chamber, could be effectively controlled by nitrogen supply and soil moisture stress. Protein contents above 16% ...
Defining a realistic control for the chloroform fumigation-incubation method using microscopic counting and 14C-substrates
Author(s):Harris, David; Horwath, William R.; Paul, Eldor A.; Horton, Kenneth A.; Jagger, Leslie; Norton, Jeannette
Date Issued:1996-11
Format:born digital; articles
Chloroform fumigation-incubation (CFI) has made possible the extensive characterization of soil microbial biomass carbon (C) (MBC). Defining the non-microbial C mineralized in soils following fumigation remains the major ...
Measuring and monitoring soil organic carbon stocks in agricultural lands for climate mitigation
Author(s):Paul, Eldor A.; Ogle, Stephen M.; Conant, Richard; Paustian, Keith
Date Issued:2011-04
Format:born digital; articles
Policies that encourage greenhouse-gas emitters to mitigate emissions through terrestrial carbon (C) offsets – C sequestration in soils or biomass – will promote practices that reduce erosion and build soil fertility, while ...
Ecology and the agricultural sciences: a false dichotomy?
Author(s):Paul, Eldor A.; Robertson, G. Phillip
Date Issued:1989-12
Format:born digital; articles
Analysis of the relationship between ecology and agriculture requires an understanding of how the two areas see themselves and each other. Both disciplines have common roots in botany, chemistry, physics, and geology, and ...
Influence of nitrogen on the decomposition of crop residues in the soil, The
Author(s):Lueken, H.; Hutcheon, W. L.; Paul, Eldor A.
Date Issued:1962-08
Format:born digital; articles
Additions of mineral nitrogen accelerated the initial decomposition rate of incorporated wheat straw, alfalfa hay and glucose when added to two soils differing widely in organic matter content. However, in the more advanced ...
Measurement of microbial biomass N:C by chloroform fumigation-incubation
Author(s):Harris, D.; Voroney, R. P.; Paul, Eldor A.
Date Issued:1997-11
Format:born digital; articles
We present a calculation for soil microbial biomass N:C ratio determined from a 10-d incubation following chloroform fumigation. The calculation is based on a mathematical model of the N content of the pre- and post-fumigation ...
Experimental warming shows that decomposition temperature sensitivity increases with soil organic matter recalcitrance
Author(s):Haddix, Michelle L.; Conant, Richard T.; Steinweg, J. Megan; Six, Johan; Paul, Eldor A.; Plante, Alain F.
Date Issued:2008-09
Format:born digital; articles
Soil C decomposition is sensitive to changes in temperature, and even small increases in temperature may prompt large releases of C from soils. But much of what we know about soil C responses to global change is based on ...
Terminal restriction fragment length polymorphism data analysis for quantitative comparison of microbial communities
Author(s):Blackwood, Christopher B.; Marsh, Terry; Kim, Sang-Hoon; Paul, Eldor A.
Date Issued:2003-02
Format:born digital; articles
Terminal restriction fragment length polymorphism (T-RFLP) is a culture-independent method of obtaining a genetic fingerprint of the composition of a microbial community. Comparisons of the utility of different methods of ...
Fractionation of soil and 15N nitrogen to separate the organic and clay interactions of immobilized N
Author(s):McGill, W. B.; Paul, Eldor A.
Date Issued:1976-08
Format:born digital; articles
Labelled 15N was added to two soils in cylinders in the field, and allowed to equilibrate for two summers of crop growth. The labelled soils were fractionated to provide information on the effect of organic and inorganic ...
