Field crops

Crops that fit a Finnish rotation. Short guides from real sources (Luke, VYR, Finnish Food Authority, Trans Farm, Martha Association, PETLA). No invented numbers.

StartFirst step: make a parcel plan.

Legumes

Nitrogen-fixing crops that break a cereal run.

Pea

A legume that breaks a cereal run and leaves nitrogen for the next crop.

Open guide

Faba bean

A long-season protein crop. On the same parcel at most every fourth year.

Open guide

Oilseeds

They break a cereal run but need a long gap.

Turnip rape

An oilseed. Only every 5th year on the same parcel, because of clubroot and Sclerotinia.

Open guide

Oilseed rape

An oilseed with the same 5-year rule as turnip rape. Winter rape has a high yield potential on a good parcel.

Open guide

Cereals

Main crops. They need a break crop against foot rot.

Oat

A spring cereal that breaks foot-rot diseases of barley and wheat.

Open guide

Barley

A spring cereal. For malting barley the best preceding crops are oat and oilseeds.

Open guide

Spring wheat

A spring cereal that suffers foot rot after barley and rye. Oat and a legume break that cycle.

Open guide

Rye

A winter cereal that spreads the workload and covers the soil over winter. Sowing date decides tillering.

Open guide

Ley

A perennial cover and a nitrogen source.

Red clover / ley

A perennial ley that breaks a cereal run and leaves nitrogen.

Open guide

Special crops

Caraway and fibre hemp.

Caraway

A perennial special crop. No yield in the sowing year. Not after Sclerotinia hosts.

Open guide

Fibre hemp

A special crop. Its full guide is already in the app – open it from here.

Root crops

Potato – change the spot every year.

Potato

Change the spot every year. Seed-potato production has a legal break; a home plot follows the Martha guide.

Rotation basics

Do not sow the same annual crop two years running (aoe.fi).
Oilseed on the same parcel only every 5th year (VYR).
Legumes: at least a 5-year rotation; faba bean at most every 4th year (Luke, VYR).
Potato: seed potato = 1 year + 2 break years (Finnish Food Authority); black scurf at most once in three years (PETLA).
Five cereal years in a row is cereal monoculture (Luke 2025).
Do not establish caraway after Sclerotinia hosts (Trans Farm).
