In parallel with the increasing food demand in the world and in Turkey, the use of high-yielding varieties and species has brought along discussions on the protection of soil fertility. Increasing use of chemical fertilizers with industrialization causes
irreparable damages on the environment and soil. Some alternative searches for reducing this damage emerged during this period. One of these searches is microorganisms living in the soil with plants. The effects of these organisms that have been living with plants and animals since the existence of the world have always been a matter of curiosity. The protection of these structures is absolutely necessary for the continuation and protection of living life. Many of these microorganisms live in common with plants in the soil. The full understanding of this process has been a matter of curiosity today. These structures in soil microbiology have many benefits from plant nutrient intake to soil micro flora. Discussions on these concepts have led to the emergence of the concept of “probiotic bacteria”.Especially the negative effects of chemical fertilizers on the soil and the environment revealed the importance of these bacteria.It manifests itself in the form of clusters in the soil close to the plant roots zone by reducing the effects that cause the reduction of soil pollution. After these effects were understood, giving the plants by inoculation caused increases in yield and quality. Today, colonized structures consisting of probiotic bacteria have emerged as a new concept with the name of bio-fertilizers. Although these fertilizers are environmentally friendly, their being sustainable in parallel with the decrease in input prices causes their use to increase rapidly. In this study, the importance and place of probiotic bacteria in plant development are emphasized.
