arable land north of 60° north latitude. Annual precipitation is usually sufficient, but it occurs almost exclusively during the winter months, making summer droughts a constant threat. In response to the climate, farmers have relied on quick-ripening and frost-resistant varieties of crops, and they have cultivated south-facing slopes as well as richer bottomlands to ensure production even in years with summer frosts. Most farmland had originally been either forest or swamp, and the soil had usually required treatment with lime and years of cultivation to neutralize excess acid and to develop fertility. Irrigation was generally not necessary, but drainage systems were often needed to remove excess water. Finland's agriculture was efficient and productive—at least when compared with farming in other European countries.
Forests play a key role in the country's economy, making it one of the world's leading wood producers and providing raw materials at competitive prices for the crucial wood-processing industries. As in agriculture, the government has long played a leading role in forestry, regulating tree cutting, sponsoring technical improvements, and establishing long-term plans to ensure that the country's forests continue to supply the wood-processing industries. To maintain the country's comparative advantage in forest products, Finnish authorities moved to raise lumber output toward the country's ecological limits. In 1984 the government published the Forest 2000 plan, drawn up by the Ministry of Agriculture and Forestry. The plan aimed at increasing forest harvests by about 3% per year, while conserving forestland for recreation and other uses.
Private sector employees amount to 1.8 million, out of which around a third with tertiary education. The average cost of a private sector employee per hour was 25.1 euros in 2004. As of 2008 average purchasing power-adjusted income levels are similar to those of Italy, Sweden, Germany and France. In
