| 摘要 | Yields of crops vary in Finland from year to year owing to the variations in climate, particularly in temperature. Since the growing season is relatively short early sowing is important and this is sometimes delayed owing to late springs. Preparations of the seedbed cannot begin before the snow has melted and the soil has both thawed and dried sufficiently. Because of this, annual crops generally cannot benefit from the first 1–3 weeks of the growing period. |
