Canola Watch 2022 exam – Section 1 – Nutrient management

The Canola Watch 2022 annual exam for Certified Crop Advisors and Certified Crop Science Consultants (and anyone else who wants to enhance their agronomy skills) has five sections:

• Nutrient management (1 CEU – 0.5 in nutrient management and 0.5 in soil and water management)
• Canola Watch fundamentals (1 CEU – 0.5 in integrated pest management and 0.5 in crop management)
• Canola Watch podcasts (1 CEU – 0.5 in integrated pest management and 0.5 in crop management)
• Canola Research Hub (1 CEU – 0.5 in integrated pest management and 0.5 in crop management)
• Canola Digest Science 2022 (1 CEU – 0.5 in integrated pest management and 0.5 in crop management)

Find them all here.

Customize the exam based on credits you need. Credits will apply in either 2022 or 2023, depending on when you pass each section. For those who pass, Canola Watch will submit names and program ID numbers to the program to have the credits counted.

For questions or additional information on this exam, please contact Jay Whetter at 807-466-3025 or whetterj@canolacouncil.org.

Section 1. Nutrient management

All farms will benefit from applying the right fertilizer products at the right rate, right time and right place – the "4Rs". This section has 10 questions on nutrient management. Answers will be found in Canola Watch content from 2022 as well as supporting resources from Canola Digest.

Achieve a minimum score of 70 per cent (7 out of 10) to receive 1 continuing education credit (CEU). Specific credits for CCAs are: 0.5 CEU in nutrient management and 0.5 CEU in soil and water management. CCA tracking number SS 56464.

7. The April 27, 2022 Canola Watch quiz asked this question: Fertilizer can damage canola seed and seedlings, so the safest is to put nothing with the seed. One exception is phosphorus. A starter rate of seed-placed phosphorus fertilizer can provide an establishment benefit for canola seedlings, especially in cool soils. What does the CCC recommend as a "starter rate"?

15-20 lb./ac. of P2O5

15-20 lb./ac. of monoammonium phosphate

30-40 lb./ac. of P2O5

30-40 lb./ac of ammonium sulphate

8. The same quiz also posed this scenario: Some drills put all seed and fertilizer down the same single-shoot opener. To reduce the risk of fertilizer damage to canola seedlings in this situation, one option is to change opener width to adjust the seeding tool's seed-bed utilization (SBU). Which of the following SBUs is safest when using higher-than-recommended rates of seed-placed fertilizer?

1" opener on 9" spacing

1" opener on 12" spacing

3" opener on 9" spacing

Disc opener on 15" spacing

9. The June 15, 2022 Canola Watch quiz asked this question: A nitrogen top dress can make financial sense for canola if growing conditions improve after seeding and updated yield potential exceeds the soil nitrogen supply. What is another situation where a top dress could make sense?

Saturated soils make it difficult for canola plants to take up nutrients from the soil.

Leaf edges are purpling.

Yellowing, browning and necrosis occurs in the middle of leaves.

Wet soil conditions accelerated nitrogen losses through leaching and denitrification.

10. Canola Watch 2022 included various posts about the new Canola 4R Advantage, which provides farmers with money to implement 4R practices. Eligible participants (a) must have current operational control over the field(s) included in the application, (b) plan to seed those fields to canola to complete the BMP, (c) be authorized to legally bind the farm business to the terms and conditions of the program, and (d) be implementing new BMP(s) that have not been part of a 4R plan for the field(s) in the past. What is the one other eligibility requirement?

Participants must have their farm businesses incorporated.

Participants must verify a history of soil testing as an indicator of 4R support.

Participants must not apply for any other OFCAF funding.


Participants must work with a 4R designated agronomist (CCA or P.Ag.).

11. Enhanced efficiency fertilizer (EEF) is one of the four best management practices that are eligible for funding through Canola 4R Advantage. A January 2022 Canola Digest article called, “When do enhanced efficiency fertilizers make sense?”, opens with a scenario where a urease inhibitor would help reduce losses. What is the example scenario?

Urea is broadcast-applied as a top-dress without enough rain to move it into the root zone.

Urea is applied too early in the fall, with warm soils high in microbial activity.

Urea is applied at high rates in the seed row with canola seed.

Urea is applied late in the fall but the farm is typically very wet in the spring.

12. The Canola Watch fundamentals article, “The right time for soil sampling,” says soil sampling just prior to seeding provides the most accurate measure of nutrients available to the crop. Fall soil sampling can be almost as accurate and has various advantages. What does the article say is the best time for fall sampling?

Any time in the month of November, just before the ground freezes.

After soil has cooled to 10°C or lower.

Whenever you can get it done.

Immediately after a rain as that’s when microbes are most active.

13. The Canola Watch fundamental article, “How much fertilizer does canola need?”, includes a recommendation for a safe rate of phosphate in the seed row. According to the article, what is one situation where seed-placed phosphorus is “especially important” for canola?

When soil pH is outside the sweet spot of 6.5-7

When the labile pool of phosphorus is very high

When soil is excessively moist

When canola seed is very small and may not have as much vigour

14. The Canola Watch fundamentals article, “Tips to apply nitrogen and sulphur in season,” says a sulphur top dress can make financial sense if canola shows signs of sulphur deficiency. In fields short of sulphur, crops can usually find enough to get past what stage without visible symptoms?

Five-leaf stage

Early rosette stage

Bolting stage

10-20 per cent flower

15. The November 2, 2022 Canola Watch quiz asked this question: The Canola Digest article "The ROI for 4R" describes scenarios where applying fertilizer following the principles of right source at the right rate, right time and right place (the four "R"s) can improve profitability. It includes this sentence, taken from a Fertilizer Canada and Canola Council of Canada report: "A yield response will only occur if crops are nitrogen limited and the ______ results in more nitrogen available to the crop compared to a conventional nitrogen product.” (Fill in the blank.)

Biological

Enhanced efficiency fertilizer

In-field top up

Variable-rate application

16. That same Canola Digest article, “The ROI or 4R,” has a few paragraphs on sectional control. It says overlap areas that receive two times the fertilizer will have lower – likely negative – profitability because those areas do not have two times the yield. It cites this sentence from the report on 4R economics: “Overlap may range from as low as two per cent in square fields with no obstacles seeded with a 40-foot drill up to ___ per cent in a field with large obstacles seeded with a 100-foot drill.” (Fill in the blank.)
