Ginseng is a profitable crop worldwide; however, the ginseng replanting problem (GRP) major threat to its production. Soil amendment non-chemical method that gaining popularity for alleviating continuous cropping obstacles, such as GRP. However, impact of soil with either cow dung or canola on GRP reduction and associated microbiota remains unclear. In present study, we evaluated effect dung, seed powder, without (control), survival seedling transplants, bacterial fungal communities, their metabolic functions. The results showed increased rate by 100 percent had remarkable positive plant growth compared control, whereas did not. Cow improved nutritional status in terms pH, electrical conductivity, NO3- , total carbon, phosphorus, available phosphorus. amplicon sequencing using Illumina MiSeq strongest negative reducing diversity. On other hand, stimulated beneficial microbes, including Bacillus, Rhodanobacter, Streptomyces, Chaetomium, while suppressing Acidobacteriota. Community-level physiological profiling analysis Biolog Ecoplates containing 31 different carbon sources activity higher utilization rates carbohydrates polymer sources, mainly Tween 40 beta-methyl-d-glucoside. These were most highly Bacillota. Furthermore, predicted ecological function analyses communities fermentation fewer functions related pathogens parasites, signifying potential enhance suppressiveness. Co-occurrence network based random matrix theory (RMT) revealed transformed microbial into connected complex network. This study first report alleviation amendment, contributes significantly our understanding how alterations via can aid alleviation.
