16S rRNA gene amplicon sequencing of acidic field soil amended with mineral and mineral-microbial conditioners (pak choi, South China)
Acidified vegetable field soil (Xinzao, Panyu District, Guangzhou, China) was amended in a six-treatment field experiment with three replicate plots: unamended control (CK), lime (SH), mineral-only conditioner (MK), and low/medium/high-dose mineral-microbial composite conditioner (LKJ, MKJ, HKJ). Initial field soil (CS) was sampled before amendment. Bulk soil was sampled at day 0 and day 40 for bacterial community profiling. The V3-V4 region of the 16S rRNA gene was amplified with primers 338F/806R and sequenced on an Illumina NextSeq 2000 (PE300). This submission contains the 39 soil metagenome amplicon samples used in the associated study.
