Economic and risk considerations of nitrogen fertilizer use in the Brown Soil Zone
Optimum use of nitrogen fertilizer requires consideration of factors that influence plant response and those that govern the decisions of producers. The response of spring wheat to soil moisture and N fertilizer was assessed ...
Why are tame hay yields declining in Saskatchewan?
Provincial agricultural production statistics show that grain crop yields have generally increased over the past 35 years while tame hay yields peaked in 1980 and have since been in decline. Weather data from 16 sites ...
Relationship between soil texture and soil organic carbon at small field scale
The capacity of a soil to store organic carbon is related to its particle size distribution, or soil texture, mainly because the capacity of clay particles to stabilize organic materials. A study of the relationship of ...
Barley after hay: grass matters!
Perennial forage crops are not traditionally grown in crop rotations in the Brown soil zone for several reasons: i) they are slow to establish; ii) they require intensive tillage to terminate; and iii) they reduce yield ...
Yield and protein of wheat and durum in Brown Soil Zone as affected by long-term tillage system and crop rotation
Three tillage-rotation experiments in the Brown soil zone showed that spring wheat and durum grain yield and protein were affected by tillage system, length of time in tillage system, crop sequence. During the initial 15 ...
Yield and protein response to N fertilization by different cultivars of spring and durum wheat
A field study to determine whether there were differences in the response of CWAD and CWRS wheat to N fertilization was conducted in two soils of southwestern Saskatchewan for four years. Using regression techniques we ...
