The mycorrhizal condition of weakened Scots pine saplings grown on ploughed sites in northern Finland
The mycorrhizal condition of nursery-grown containerized Scots pine (Pinussylvestris) saplings planted in clear-cut and ploughed sites in northern Finland was investigated. The saplings, 15 years old on average, were classified on the basis of shoot condition into injured and healthy-looking sapling...
