The purpose of our study was to determine the effect of microirrigation and organic fertilization on the vitality of Scots pine (Pinus sylvestris L.) seedlings and their mycorrhizal structure, as well as the occurrence of soil mites (Acari) after treatment of edaphon inoculation. Nursery experiments were carried out in 2003-05. It was found that studied factors influenced seedling vigour, mycorrhizal colonization, soil properties and the occurrence of mites.
