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, ...
Gaseous nitrogen losses from soils under zero-till as compared with conventional-till management systems
Author(s):Paul, Eldor A.; Rennie, D. A.; Aulakh, M. S.
Date Issued:1984-01
Format:born digital; articles
The gaseous losses of N from conventional-till (CT) and zero-till (ZT) crop fields were 3 to 7 and 12 to 16 kg N ha−1 y−1, respectively. In contrast, losses from CT and ZT fallow were severalfold higher, namely, 12 to 14 ...
Influence of plant residues on denitrification rates in conventional and zero tilled soils, The
Author(s):Paul, Eldor A.; Rennie, D. A.; Aulakh, M. S.
Date Issued:1984-07
Format:born digital; articles
A field study was conducted with treatments consisting of a factorial combination of N (0 or 100 kg N ha−1 as (NH4)2SO4, straw (0 or 3000 kg ha−1), and two tillage treatments. Ground straw was mixed with the plow layer of ...
