“…Bioameliorant can be specially formulated so that it contains several good microbes that function in the rhizosphere, such as Bacillus, Bacillariophyta, Bacteroidetes, Basidiomycota, Chloroflexi, Chlorophyta, Firmicutes, Planctomycetes, Proteobacteria which can dissolve nutrients and make a major contribution to soil fertility (Jose et al, 2024). Rhizobacteria are natural microorganisms that live in soil and are able to colonize the plant root system directly as a growth regulator (ZPT) for plants (Zarpelon et al, 2016). Bacteria from PGPR have an impact that promotes growth and significantly improves plant quality, as well as the potential for good application in plant cultivation, so that it can contribute to environmental protection and economic growth (Zhang et al, 2024).…”
