Canada is the world’s leading producer of canola, with 21.4 million acres grown, accounting for 25 percent of the world’s crop. In the United States, canola accounts for around 2.2 million acres of crops grown with North Dakota being the leading producer. 

Once canola is harvested, it is processed into oil and meal, which are used for various products like cooking oil, biodiesel, and animal feed.  

To help lessen crop stress factors and increase yields, canola requires many nutrients to reach its fullest potential. The Andersons offer a wide range of solutions that help canola crops reach their maximum potential.  

Nutrient Deficiencies

Nitrogen is mobile in the plant. Nitrogen is the most limiting nutrient found in most canola crops. Deficiencies will appear with premature yellowing of the lower leaves and the plant will start to look thin and spindly.
Phosphorus is responsible for capturing and converting the sun’s energy. Plants deficient in phosphorus will appear stunted and have a dark green or purple (if severe) color to the older leaves.
Deficiencies will appear on the lower leaves first due to potassium being mobile in the plant. Yellowing will start to appear on the leaf edges followed by the withering of the leaf.
Deficiencies will look like patchy areas in fields where soil organic matter is low. Flowers will be a very light yellow or white in color followed by small poorly filled pods. Leaves will roll inwards and become thick and brittle.
Boron is essential in the flowering process of canola. Young leaves will start to show necrotic spots and curl while the main stem will be stunted. Flowers will form but later abort when the plant is deficient.
Deficiencies will appear when there is necrosis on the pods. Flowers will also start to fall over causing the flower heads to die, reducing yields.
