Before field work
Planning and rotation
What happens
Field history, crop sequence, residue, weeds, diseases, insects, soil conditions, moisture, seed identity, equipment, labour, and marketing plans meet before field work begins.
Oil-chain meaning
Decisions made before seeding establish the biological and operational setting for crop production, harvested grain, delivery, and the eventual processing stream.
Why it reaches the kitchen
Rotation is far upstream of cooking, but it explains why canola oil begins within a multi-year farm and food system rather than at the grocery shelf.
