The challenge of environment management is a sustainable development of both environmental systems and the green economy. The main objective of this study was the optimization and testing of plant growth-promoting rhizobacteria soil biopreparation and soil amendments as the alternative to or to help offset use of mineral soil fertilizers. A field study was conducted on a degraded area to improve plant biomass yield using inoculated bacteria. Moreover, organic additives (sewage sludge) and inorganic fertilizers were also used to compare their effectiveness. The conducted study investigated the combined effect of immobilized microbial consortium and soil substrates for plant growth (red fescue) on degraded areas and confirmed synergistic interactions between plants, microorganisms and soil substrates in the process of phytoremediation. The formulation consisted of immobilized bacterial consortia having mechanisms for the synthesis of compounds preferably affecting growth and development of (crop) plants. The conducted studies confirmed that the PGPR bacteria used in the experiment have the potential to promote plant growth, increase organic nitrogen the bioavailable P pool in soil. The results of the field study (synergy effect of alternative fertilization and bacteria) can be used to create effective methods in assisted soil bioremediation. This approach has a high social acceptance and reduces resource consumption of fertilizers having an impact on sustainable development. Implementing methods of supporting plant growth using microorganisms can undoubtedly contribute to the development of 'green' resource management.
环境管理的挑战是环境系统和绿色经济的可持续发展。本研究的主要目的是优化和测试植物促生根际细菌土壤生物制剂和土壤改良剂，作为替代或帮助抵消矿物土壤肥料的使用。在退化地区进行了一项田间研究，使用接种细菌来提高植物生物量产量。此外，还使用了有机添加剂（污水污泥）和无机肥料来比较它们的效果。进行的研究调查了固定化微生物联合体和植物生长的土壤基质（红羊茅）对退化地区的综合影响，并证实了植物、微生物和土壤基质在植物修复过程中的协同相互作用。该配方由具有合成化合物机制的固定化细菌联合体组成，这些化合物优选影响（作物）植物的生长和发育。进行的研究证实，实验中使用的 PGPR 细菌具有促进植物生长、增加土壤中有机氮可利用磷库的潜力。田间研究的结果（替代施肥和细菌的协同效应）可用于创建有效的辅助土壤生物修复方法。这种方法具有很高的社会认可度，减少了对可持续发展有影响的肥料资源消耗。使用微生物来支持植物生长的方法无疑可以为“绿色”资源管理的发展做出贡献。
