Dynamics of carbon dioxide evolution from decomposing wheat straw
Increasing concentration of CO2 in the atmosphere is a concern because of the potential for global warming. Carbon exchange between soil and the atmosphere has an important role in the global C cycle, but partitioning soil ...
Evaluation of furrow openers and packers for conservation tillage
Producers in the Canadian Prairies are increasingly adopting conservation tillage systems. A large part of the success of conservation tillage rests on the availability of equipment able to seed into standing stubble. In ...
Effect of seeding date on yield and quality of winter wheat (cv. Norstar) grown on stubble and chemical fallow in south western Saskatchewan
Winter wheat (cv. Norstar) was seeded at one site (clay loam stubble) in 1984-85, and three sites (clay loam stubble and chemical fallow, sandy loam stubble, and heavy clay stubble) in 1985-86 and 1986-87. Conditions were ...
Microbial community structure under various wheat-based cropping systems
The effects of cropping systems on soil biological quality are slow to develop. We sampled the soil of a 36-year old long-term experiment established on an Orthic Brown Chernozem, at Swift Current SK, in the fall of 2003, ...
What agronomic practices can reduce the effect of Fusarium head blight on durum wheat in Saskatchewan?
Fusarium head blight (FHB) has become an important disease of cereals in moist regions of western Canada. This disease has played an important role in contributing to lower grain yields and substantial downgrading of durum ...
Spring wheat response to nitrogen and water
Yield and water use of paired-row versus conventionally seeded spring wheat at Swift Current
From 1986 to 1989 at the Swift Current Research Station, a hard red spring wheat (cv. Leader) was planted in north-south rows with row spacings of: a) 25 cm (conventional seeding-CS), and b) two rows 10 cm apart with 50 ...
