The studies were conducted in the years 2000–2002 at the Experimental Station of Czesławice near Nałęczów on a field of monocultures of runner bean and soybean. The subject of the studies was the rhizosphere soil of these plant species. The experiment of each plant included 2 combinations, i.e. with dressing the seeds with Zaprawa Oxafun T and without dressing the seeds (control). Results of the microbiological analysis of the rhizosphere soil of runner bean and soybean showed that the plants grown of the seeds dressed with Zaprawa Oxafun T always gave a greater number of bacteria colonies, Bacillus spp. and Pseudomonas spp. but a smaller number of fungi colonies than in the control combination. In comparison to the rhizosphere soil of soybean, the rhizosphere soil of runner bean contained much more bacteria and a much lower number of fungi colonies. Among the obtained saprotrophic macroorganisms, a more numerous group of antagonistic bacteria and fungi was achieved from the rhizosphere soil of runner bean than from the rhizosphere soil of soybean. Whatever the plant species, considerably more antagonistic bacteria and fungi occurred in the combination with Zaprawa Oxafun T as compared to the control. The plant species as well as the introduction of Zaprawa Oxafun T into the soil together with the seeds had a considerable influence on the quantitative and qualitative composition of the populations of soil microorganisms.

This study evaluated the effect of Pseudomonas strains and arbuscular mycorrhiza fungi (AMF) in enhancing strawberry yield and phenolic and antioxidant capacity on a phosphorus (P) deficient calcareous soil. The experiments were conducted in three replicates with six treatments (four Pseudomonas strains, AMF and control) and three rates of P-fertilizer (0, 75, 150 kg P ha–1). Application of higher phosphate rates decreased total antioxidant capacity, total phenolic and flavonols content, whereas AMF and Pseudomonas strains increased quality and P concentration of fruit. The use of AMF and Pseudomonas strains resulted in better quality when used along with 75 kg P ha–1. These results demonstrated that the rhizospheric microorganisms improved the quality of fruit, especially when they applied in combination with lower rates of chemical fertilizers. Therefore, application of these microorganisms in sustainable agriculture is recommended.
