Abstract: The aim of the study was to assess the impact of the use of biofertilizers on the degree of colonization of cucumber and tomato plant roots by arbuscular mycorrhizal fungi and the number of AMF spores in the rhizosphere soil. Two experiments were carried out in containers on cucumber and tomato plants under field conditions. The plants were fertilized with standard NPK fertilizer, mineral fertilizers: POLIFOSKA 6, Super FOS DAR 40 and urea in the full recommended dose and reduced by 40%, microbiologically enriched, and only with strains of beneficial microorganisms (Bacillus spp., Bacillus amyloliquefaciens, Paenibacillus Polymyxa, Aspergillus niger, Purpureocillium lilacinum). The experimental results showed a beneficial effect of the POLIFOSKA 6 mineral fertilizer enriched with beneficial bacteria of the Bacillus genus on increasing the colonization of the roots of tomato and cucumber plants by arbuscular mycorrhizal fungi. Compared to the control, fertilization with microbiologically enriched urea at doses of 100% and 60% reduced the frequency of mycorrhizas in the roots of tomato and cucumber plants. The use of POLIFOSKA 6 100% and Super FOS DAR 40 at a dose of 60% resulted in an increase in the number of spores in the rhizosphere soil. The experimental results will allow the development of new biofertilizers as alternative methods of fertilizing plants and improving soil quality compared to standard mineral fertilization.
