Measurement of the polysaccharide content of soils
Author(s):Acton, C. J.; Paul, E. A.; Rennie, D. A.
Date Issued:1963-01
Format:born digital; articles
The polysaccharide content of two soils, measured by precipitating and weighing the microbial gums from the fulvic acid fraction of soil organic matter, and by colorimetric analyses using anthrone, was increased appreciably ...
Relationship of polysaccharides to soil aggregation, The
Author(s):Acton, C. J.; Rennie, D. A.; Paul, E. A.
Date Issued:1963-07
Format:born digital; articles
Studies were conducted on two soil types to determine whether variations in level of aggregation, induced by adding wheat straw were accompanied by significant changes in the polysaccharide content of the soils. The addition ...
Natural nitrogen-15 abundance of soil and plant samples
Author(s):Rennie, D. A.; Johns, L. E.; Paul, E. A.
Date Issued:1976-02
Format:born digital; articles
Nitrogen isotope analysis of total soil N and soil-derived nitrate for nine selected Chernozemic and Luvisolic Ap horizons showed mean δa15N values based on atmospheric abundance of 8.8. Luvisolic soils were characterized ...
Effect of various clover management practices on gaseous N losses and mineral N accumulation, The
Author(s):Aulakh, M. S.; Rennie, D. A.; Paul, E. A.
Date Issued:1963-08
Format:born digital; articles
A 2-yr field study was carried out to assess gaseous losses of N as N2O + N2 from two Black Chernozemic soils, where during year 1 wheat was underseeded to clover and in year 2, the clover in late June was (a) green-manured ...
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, ...
