Seed Bed PreparationSeed Bed Preparation Canola is very susceptible to soil Canola is very susceptible to soil

crustingcrusting Seedbed must be firmSeedbed must be firm Seed and soil moisture is critical for Seed and soil moisture is critical for

rapid seed emergence so seeding in dry rapid seed emergence so seeding in dry soil is not recommendedsoil is not recommended

Seedbed should be prepared in a way to Seedbed should be prepared in a way to prevent wind erosion since seedlings are prevent wind erosion since seedlings are easily damaged by drifting soileasily damaged by drifting soil

Harrowing is not recommendedHarrowing is not recommended

Fertilizer ApplicationFertilizer Application Nitrogen and Sulfur are key elements for Nitrogen and Sulfur are key elements for

high yieldshigh yields Nitrogen or potash shouldn’t be applied in Nitrogen or potash shouldn’t be applied in

direct contact with seeds but should be direct contact with seeds but should be applied in a band at least 2 inches away applied in a band at least 2 inches away from seedsfrom seeds
