Question 1

What is crop rotation?

Accepted Answer

Crop rotation is the practice of growing different plant families in the same field over successive seasons rather than planting the same crop every year. It breaks pest and disease cycles, balances soil nutrients, improves soil structure, and can increase yields 10–25% compared to continuous monoculture (FAO, 2023).

Question 2

Why is crop rotation important?

Accepted Answer

Crop rotation is important for four reasons: (1) it breaks family-specific pest and disease cycles that overwinter in soil, (2) it balances nitrogen by alternating heavy feeders with nitrogen-fixing legumes, (3) it improves soil structure through varying root depths, and (4) it reduces weed pressure by disrupting weed life cycles. Farms using rotation often see meaningful yield gains without increasing inputs.

Question 3

What is a 3-year crop rotation?

Accepted Answer

A 3-year rotation cycles three different plant families through the same field over three seasons. A classic example: Year 1 heavy feeder (tomato, corn, cabbage) → Year 2 nitrogen-fixing legume (bean, pea, clover) → Year 3 light feeder or root crop (onion, carrot, lettuce). The legume year restores nitrogen the heavy feeder depleted; the light-feeder year gives soil a rest before cycling back.

Question 4

What is a 4-year crop rotation?

Accepted Answer

A 4-year rotation is the gold standard for vegetable gardens and small farms. It cycles four plant families across four years: Year 1 heavy feeder (solanaceae or cucurbits) → Year 2 nitrogen-fixing legume → Year 3 moderate/light feeder (brassica or allium) → Year 4 root crop. This longer cycle gives each family a 3-year break, dramatically reducing disease pressure compared to 2- or 3-year rotations.

Question 5

What should I plant after tomatoes?

Accepted Answer

Tomatoes are heavy feeders in the solanaceae family (along with potato, pepper, eggplant). Follow tomatoes with a nitrogen-fixing legume — bean, pea, or clover — to restore soil nitrogen. Avoid planting any other solanaceae crop for at least 2–3 years to prevent verticillium wilt, blight, and nematode buildup. Brassicas (cabbage, broccoli) are also a good follow-up.

Question 6

What should I plant after corn?

Accepted Answer

Corn is a heavy feeder that depletes soil nitrogen. Plant a nitrogen-fixing legume after corn — soybeans, beans, peas, or clover — to restore fertility naturally. The classic US Midwest rotation is corn → soybean, delivering consistent yields for both crops. Avoid back-to-back corn years, which increase rootworm pressure and nitrogen costs.

Question 7

How many years between planting the same crop?

Accepted Answer

The minimum gap depends on the crop family: solanaceae (tomato, potato, pepper) need 3–4 years, brassicas (cabbage, broccoli) need 3–4 years, cucurbits (squash, cucumber) need 2–3 years, and grains (wheat, corn) need 1–2 years. These gaps break the disease and pest cycles specific to each family — shorter rotations dramatically increase soil-borne disease pressure.
