Introduction The objective of this study is to examine the impact various oyster shell soil conditioners, which are primarily composed shells, on growth tomatoes in acidic soil. Moreover, aim investigation analyze variety and structure bacterial populations close proximity tomato roots while also contributing understanding physical, chemical, biological mechanisms conditioners. Methods Tomato plants were grown red three groups: a control group treatment that used two types OS (oyster powder) OSF powder with organic microbial fertilizer). A range physicochemical properties measured differences inter-soil parameters plantings. In addition, utilized CTAB (Cetyltrimethylammonium Bromide) technique extract DNA from order investigate effects conditioner composition diversity populations. Utilizing high-throughput sequencing technologies index analysis, adjacent plant then evaluated. Ultimately, correlation analysis was explore relationship between environmental factors relative abundance bacteria inter-root zone plants. Results findings indicated conditioners capable modifying characteristics This evidenced by significant increases total nitrogen (16.2 59.9%), carbon (25.8 27.7%), pH (56.9 55.8%), electrical conductivity (377.5 311.7%) groups, respectively, compared ( p < 0.05).
