Our investigation determined the influence of organic fertilization and mulching (edaphon inoculation) on the vitality of European larch (Larix decidua Mill.) seedlings and their mycorrhizal structure, as well as the occurrence of soil mites (Acari). Nursery trials were conducted in 2005-07. It was confirmed that the investigated factors affected the growth of seedlings and mycorrhizal colonization, as well as soil properties and the occurrence of soil mites.
