Trends in crop production in the Canadian prairies
Dryland agriculture in the Canadian prairies is continuously confronted by change. In response to growing competition in the global market place producers have sought alternative crop production methods in order to maintain ...
Water use efficiency and precipitation use efficiency of crops in the semiarid prairie
The importance of water use efficiency (WUE) in crop production, in the semiarid prairie, is based on the fact that the available water is the most limiting factor influencing crop production. This poster compares water ...
Effect of fallow frequency on soil water conservation in the semi-arid region of Saskatchewan
The effects of fallow frequency on soil water conservation were quantified for a 40 yr (1967-2006) field experiment conducted on a medium textured Orthic Brown Chernozem (Aridic Haploboroll) in semiarid southwestern ...
Where is nitrogen going in long-term cropping systems?
Fertilizer nitrogen use efficiency (NUE) is normally low, and has led to the idea that a large proportion of N applied as fertilizer is lost from the soil. However, N balances calculated for a long-term rotation study at ...
Seasonal variation in the soil microbial community in wheat-growing soil and influence of C, N, and P inputs
It has long been know that N and P fertilization increases plant growth and yield, but the impact of fertilization on soil microorganisms has rarely been considered. Long-term plots (36-year old) under fallow-wheat-wheat ...
Effect of cropping frequency on C storage in Canadian prairie soils
Available water is the main constraint to crop production on the Canadian prairies. Summerfallow has been used to counter this problem, but frequent summerfallowing promotes soil organic matter (SOC) loss. Although ...
