Abstract
Gradually effective microorganisms come into use in forestry. The paper presents the results of containerized oak (Quercus robur L.) seedlings cultivation using microbial fertilizers. The studies were conducted at the greenhouse complex of Danylivske research forestry of URIFFM in 2011–2014. Containerized oak seedlings cultivated according to the technology developed by scientists of URIFFM, using the substrate of soil and peat (3 : 1) in the open ground with irrigations. In experiments with using microbial fertilizes for oak seedlings cultivation, Azotobakteryn (10 g/l), Polimiksobakteryn (10 ml/l and 20 ml/l), Ryzobrazyn (40 ml/l), Biophyte (15 ml/l), Hetomik (1 ml/l) and Baikal (100 ml/l) were used in "pure" form as well as with the addition of Humate (1.5 g/l), ammonium nitrate (0,3 %), Agrolife (5 g/container) and NPK fertilizer (40 g/m2). Fertilizing was made by irrigation on the basis of 5 l of preparation solution on 1 m2 of container surface. The most effective of the preparations tested were Polimiksobakteryn 20 ml/l with Humate 1,5 g/l and Baikal-1 volume in 1:100 with Humate 1,5 g/l, mixed in the substrate in the form of the aqueous suspension. Fertilizing was made twice during the vegetation period: immediately after planting acorns in the substrate and after the appearance of two or three true leaves, and Baikal with mineral fertilizers. Taking into account that the seedlings are planted in containers in silvicultural area together with substrate inoculated with beneficial live microorganisms, we can predict their positive after-effect on the growth of forest plantations.
