Temporal soil bacterial community responses to cropping systems and crop identity

Temporal soil bacterial community responses to cropping systems and crop identity in dryland agroecosystems of the Northern Great Plains. We evaluated soil microbial community responses to contrasting cropping systems at the Montana State University Fort Ellis Research and Teaching Center in Bozeman, MT. The experimental design consisted of a five-year crop rotation under three different management systems: chemical inputs with no-tillage, a USDA-certified organic system with tillage, and a USDA-certified organic system with targeted sheep grazing for cover crop termination and weed management.

北大平原旱地农业生态系统中土壤细菌群落随时间对种植制度与作物种类的响应。本研究于蒙大拿州博兹曼市的蒙大拿州立大学福埃利斯研究与教学中心开展，评估了不同种植制度下的土壤微生物群落响应。实验设计包含三种管理体系下的五年轮作模式：一是施用化学投入品的免耕体系；二是经美国农业部（USDA）认证的有机耕作体系；三是经美国农业部认证的有机体系，采用定向绵羊放牧以完成覆盖作物生长终止与杂草防控。
