QUIZ – Fall testing

Agronomy continues! Four questions to inspire fall testing for soil nutrients, disease, plant counts and canola quality.

1. What is the best time to soil sample this fall if using the results to plan next year's application rates?

Right after harvest

Before the first frost

When soils are warm and moist

Just before freeze-up

2. Did you see a lot of verticillium stripe in canola this year? While we don’t have known verticillium stripe resistance, which canola trait could possibly reduce the verticillium stripe risk?

Verticillium stripe

Blackleg resistance

Clubroot resistance

Lodging resistance

Pod shatter resistance

3. With fall stubble counts, growers may learn more about the relationship between yield, plant count and specific cultivars. One possible factor in higher than expected yields for some canola growers this year was very good stand establishment. What is the typical drop in canola plant stand from spring to fall?

No drop

5 to 10 per cent

10 to 15 per cent

20 to 25 per cent

4. The Canadian Grain Commission’s Harvest Sample Program is accepting samples from farmers until November 30. Growers who submit samples (from good fields or challenging fields) get an unofficial grade, dockage assessment, oil content and green counts. The survey also provides Canada with a good indicator of overall canola quality. What was the average canola oil content in 2022, based on Harvest Sample Program results?

38.8 per cent

42.1 per cent

44.5 per cent

48.3 per cent
