Plan a healthy rotation before you commit fields
Farming is Farthest Frontier’s deepest system, and its crop rotation is the game’s most-asked question. Every crop changes a field’s soil fertility, weeds creep in over the years, and planting the same crop family too often invites crop disease. This crop rotation planner simulates all three at once so you can design a rotation that keeps fields productive year after year.
Soil fertility and restorer crops
Heavy feeders like wheat, rye, leek and cabbage drain fertility fast; clover, beans and peas restore it; compost tops it up. The planner tracks fertility year by year and warns when a field is heading for 0%, so you know exactly when to slot in a restorer or apply compost. Fertility-hungry crops (wheat, leek, flax) lose the most yield on poor soil, which the yield index reflects.
Weeds and weed suppression
Weeds accrue on a field and steal yield. Buckwheat is the strongest crop weed-suppressor, with clover and rye close behind, and a Field Maintenance year clears the most of all. The planner’s weed line shows when weeds are climbing so you can schedule a suppressor or a maintenance year before they bite.
Crop disease and family spacing
Diseases build up by crop family — the brassicas (turnip, cabbage), the cereals (wheat, rye, buckwheat) and the legumes (beans, peas) each share diseases, while carrot and buckwheat cross into several families. Plant a family too soon after itself and you risk an outbreak and a heavy yield loss. The planner flags the risky years and the disease at fault, so you can space families out or drop in clover or a maintenance year between them.
How to use the planner
- Set each field’s size, starting fertility and starting weed level.
- Pick a crop for each year of the rotation; colours and the simulation update instantly.
- Toggle compost on any year to add fertility.
- Watch the fertility & weed chart and the per-year table, and read the warnings.
- Open the Advanced panel to tune the estimated weed/disease constants to your patch.
- Hit “Copy share link” to share your whole rotation as a URL.
A note on the numbers
The per-crop numbers come from the Farthest Frontier game data and the Configure Crops mod, and may have been retuned in the live patch. The settlement-level values — weed accrual, compost strength, and the disease grace period and penalty — are community estimates, all editable in the Advanced panel. Treat the simulation as a directional planning aid, not exact game maths.
Frequently asked questions
Is there a Farthest Frontier crop rotation planner?
Yes — this is a free, browser-based Farthest Frontier crop rotation planner. You assign a crop to each field for each year of the rotation, optionally add compost, and instantly see how soil fertility and weed level rise and fall over the cycle, plus warnings when you plant crops from the same disease family too close together. Nothing to download, no account.
What is the best crop rotation in Farthest Frontier?
A healthy rotation alternates heavy feeders (wheat, rye, leek, cabbage) with fertility restorers (clover, beans, peas) and never plants two crops from the same disease family back to back. For example: Wheat → Beans → Cabbage → Clover keeps fertility from collapsing, suppresses weeds, and spaces out disease families. Use the planner to test a rotation and watch the fertility and weed lines before you commit it in-game.
How does soil fertility work in Farthest Frontier?
Each crop changes a field's fertility when harvested: grains like wheat (+6) and rye (+5) deplete it heavily, while clover (−3) and the legumes beans and peas (−1) restore it. Compost adds fertility too. Low fertility means smaller harvests, and fertility-hungry crops like wheat, leek and flax suffer the most. Rotating restorers between heavy feeders — and applying compost — keeps a field productive.
How do I stop crop disease in Farthest Frontier?
Diseases build up in the soil by crop family. Planting crops that share a family in consecutive years (or within the grace period) risks an outbreak and a big yield loss. The brassicas (turnip, cabbage), the cereals (wheat, rye, buckwheat) and the legumes (beans, peas) each share diseases, and carrot and buckwheat cross into several families. Space same-family crops apart, and slot in clover or a Field Maintenance year between them — the planner flags the risky years for you.
How do weeds work, and how do I control them?
Weeds accrue on a field over time and steal yield. Some crops suppress weeds while they grow — buckwheat (−10) is the strongest crop suppressor, with clover and rye also strong — and a Field Maintenance year (−18) is the best cleaner of all. The planner tracks the weed level year by year so you can see when to slot in a suppressor or a maintenance year.
Are the crop numbers accurate?
The per-crop numbers — fertility change, weed suppression, maturation, frost and heat tolerance — come from the Farthest Frontier game data (dump v1.x (crop data dump v0.7.4)) cross-checked against the 'Configure Crops' mod, and may have been retuned slightly in the live patch. The settlement values (weed accrual rate, compost strength, and the disease grace period and penalty) are community estimates and are editable in the Advanced panel.
