Soil metagenome Raw sequence reads

To parse effects of interseeding cover crops and soil N status on bacterial composition, we used high throughput 16S ribosomal RNA (rRNA) gene amplicon sequencing to examine the taxonomic profiles of bulk soil under each treatment in the fall (December 2017) and spring (June 2018). This factorial field experiment included three CC treatments (interseeded ryegrass, post-harvest seeded cereal rye, and no CC), two rates of fertilizer application, and corn harvested for grain and silage in an organically managed cropping system.

为解析间作覆盖作物和土壤氮素状况对细菌群落组成的影响，本研究采用高通量16S核糖体RNA（rRNA）基因扩增子测序技术，分析了秋季（2017年12月）和春季（2018年6月）各处理措施下土壤总体的分类学特征。该因子田间试验涵盖了三种覆盖作物处理（间作黑麦草、收获后播种的谷物黑麦草以及无覆盖作物处理）、两种施肥速率以及有机管理模式下收获用于粮食和青贮的玉米。
