The effect of nursery measures on mycorrhizal colonisation of Scots pine and occurrence of soil mites

摘要

The aim of the study was to determine the influence of organic fertilization (treated sewage sludge with addition of bark or sawdust) and mulching (forest edaphon inoculation) on the vitality of Scots pine (Pinus sylvestrisL.) seedlings and their mycorrhizal structure, as well as the occurrence of soil mites (Acari). Nursery experiments were carried out in 2005 to 2007. It was stated that the studied factors influenced seedling vigour, mycorrhizal colonization, soil properties and the occurrence of mites.
