| Abstract : | In the years 2014-2015, at the ZUT Szczecin Experimental Station in Lipnik (53°20′35″N14°58′10″ E) a study was conducted to assess the impact of mycorrhizal fungi on selected soil properties and on the content of macro-and micronutrients in a sandy under gardening use. Mycorrhization was conducted with ectomicorrhizal mycelium, symbiotic for plants of the olive family. The isolate was obtained from natural ecosystems in Croatia. It contained symbiotic mycorrhizal fungi (Glomus spp, Gigaspora spp, Pochonia spp, Lecanicillum spp) and root bacteria (Bacillus spp). The soil on which the experiment was conducted belongs to the typical rusty soils group (CPS, 2011), classified as Haplic Cambisol according to IUSS Working Group WRB (2015). The experiment was conducted in the randomized block design in five replications (one shrub – one replication) with four varieties of sea buckthorn bushes (Hippophaë rhamnoides L.). The experiment included two factors: I – mycorrhiza: O – control treatments without mycorrhiza; M – treatments with mycorrhiza, II – four varieties of sea buckthorn: 'Ascola', 'Habego', 'Hergo' and 'Leikora'. Soil samples taken from each experimental plot (mycorrhizal and non-mycorrhizal plots) were used for the following assays: pH, Corg., organic matter, macro- and micronutrients. Mycorrhizal soil was characterised by a higher content of Corg., organic matter and N, P, Mg, Ca, Zn. The varieties differentiated the traits under study to a lesser extent than mycorrhiza. Based on the study it is not possible to determine univocally whether the changes in the soil under the influence of mycorrhiza are permanent, therefore it is necessary to continue the research. |
