EC cannot help make VR strategies more consistent

Key Result: While soil electrical conductivity (EC) measurement is a strong indicator of soil clay and moisture content, it cannot help to make variable rate (VR) fertilizer programs more consistent. Producers using VR should be prepared to use a specific strategy for each field each year. Project title, Principal investigators: “Understanding soil variability for effective...

Herbicides that could improve cleavers control

Cleavers species are difficult to control and can cause downgrading and reduce crop quality.

It is important to note that, as of October 2016, clomazone is not yet registered and quinclorac should not be used on canola due to maximum residue limit (MRL) issues. Until exporters and processors are confident that they can ship quinclorac-treated canola without trade concerns, growers are advised to avoid this marketing risk by using other cleavers control methods.

Identification of superior crop rotations

Key Result: The southeast Peace region has the highest intensity of canola acres and short canola rotations in the western Canadian Prairies. However, this study suggests that this may not be the best choice for growers in terms of long term yield, cropping system sustainability, soil moisture use, root health and economics. Project Title, Principal...

The fate of sulphur fertilizers in the soil

Key Result:  Choosing the most suitable sulphur (S) fertilizer for the conditions can be difficult. This study found that soluble sulphates, thiosulphate and gypsum are effective at providing early supplies of plant-available sulphate in the seed row. An early supply of sulphate appears to be important for plant S uptake and yield. Project title, Principal...

Investigation into pod drop and pod retention resistance

Key result: Seed losses at harvest can be significant. This study provides insight into pod drop and the factors impacting it. The pod retention measurement method developed and validated in this study can be used in future studies. Results from this study also suggest that pod retention is a heritable trait and could be exploited by...
