How to Plan a Crop Rotation
Crop rotation is the practice of growing different plant families in the same field across successive seasons. It is one of the oldest and most effective tools in sustainable agriculture — breaking pest cycles, balancing soil nutrients, and lifting yields 10–25% compared to continuous monoculture (FAO, 2023).
The Four Principles of Good Rotation
- Family break: Never plant the same plant family back-to-back. Most soil-borne diseases are family-specific — rotating breaks the cycle.
- Feeder succession: Follow heavy feeders (tomato, corn, cabbage) with nitrogen-fixing legumes (bean, pea, clover) to restore fertility before the next heavy-feeder year.
- Root depth variation: Alternate deep- and shallow-rooted crops to improve soil structure and tap different nutrient layers.
- Minimum return interval: Solanaceae (tomato, potato) and brassicas (cabbage) need 3–4 years before returning; cucurbits 2–3 years; grains 1–2 years.
Classic 4-Year Rotation Example
Year 1: Heavy feeder (tomato, corn) → Year 2: Legume (bean, pea) → Year 3: Moderate feeder (brassica, allium) → Year 4: Light feeder or root crop (lettuce, carrot). This covers the four main rotation “slots” and gives every family a 3-year break.
Why Cover Crops Matter
A winter cover crop between cash crops — rye, clover, or vetch — protects soil from erosion, adds organic matter, and (if legume) fixes extra nitrogen. Adding a cover crop to a 4-year rotation typically boosts overall yield 5–10% versus bare-winter rotation.
