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 ...

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 ...
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, ...
