Effect of nitrification inhibitor on N immobilization and release of 15N from nonexchangeable ammonium and microbial biomass
Author(s):Paul, E. A.; Juma, N. G.
Date Issued:1983-05
Format:born digital; articles
The disposition of 15N-aqua NH3 and 15N-solution urea in the presence and absence of a nitrification inhibitor [4-amino-1,2,4-triazole (ATC)] was measured under field conditions. ATC caused a 15% greater recovery of ...
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 ...
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 ...
Carbon economy of soybean-rhyzobium-glomus associations
Author(s):Paul, E. A.; Harris, D.; Pacovsky, R. S.
Date Issued:1985-11
Format:born digital; articles
Carbon uptake and allocation in plants that were largely dependent on microbial symbionts for N and P was compared to that in plants given inorganic fertilizer. Soybeans (Glycine max L. Merr.) were grown in sterilized soil ...
Gaseous nitrogen losses from cropped and summer-fallowed soils
Author(s):Aulakh, M. S.; Rennie, D. A.; Paul, E. A.
Date Issued:1982-02
Format:born digital; articles
A study designed to assess gaseous losses of N as N2O and N2 from soils of conventional till fields seeded to wheat in the Chernozemic soil region of Saskatchewan, together with limited supporting laboratory investigations, ...
Effects of vesicular-arbuscular mycorrhiza on 14C and 15N distribution in nodulated fababeans
Author(s):Paul, Eldor A.; Pang, P. C.
Date Issued:1980-05
Format:born digital; articles
A two-compartment growth chamber in which the aboveground plant materials were exposed to 14CO2 and the belowground portion was exposed to 15N2 under normal atmospheric pressure was designed for carbon and nitrogen transfer ...
Effect of labile inorganic phosphate status and organic carbon additions on the microbial uptake of phosphorus in soils
Author(s):Chauhan, B. S.; Stewart, J. W. B.; Paul, E. A.
Date Issued:1981-05
Format:born digital; articles
The effect of labile inorganic phosphate (Pi) status of the soil on the decomposition of added cellulose and on the immobilization, mineralization, and redistribution of native and added P in soils was studied in a greenhouse ...
Comparisons between P-fertilized and mycorrhizal plants
Author(s):Paul, Eldor A.; Bethlenfalvay, G. J.; Pacovsky, R. S.
Date Issued:1986-01
Format:born digital; articles
In experimentation with vesicular-arbuscular mycorrhizal (VAM) fungi, the availability of non-VAM control plants of equal size to VAM plants is a fundamental requirement. The purpose of this work was to determine nutrient ...
Microbial effects
Author(s):Paul, Eldor A.; Hardy, Ralph W. F.; Lamborg, Marvin R.
Date Issued:1983?
Format:born digital; articles
The recommendations for microbiological research needs are based on the following general scenario: a) increased atmospheric CO2 will increase crop productivities by 10-40%, depending on crop and geographic area, which in ...
Nutrient and energy flows through soil microbial biomass
Author(s):Paul, Eldor A.; Voroney, R. P.
Date Issued:1980
Format:born digital; articles
The recognition and recent studies of the role of living organisms (biomass) in carbon, nitrogen and phosphorus flows in nature have stressed the role of the microorganisms as sources and sinks for nutrients, in addition ...
