16S r RNA sequencing of rice field soil

Astragalus sinicus (Chinese milk vetch) is a well-established resource of organic fertilizer widely used in paddy soils to partially replace chemical fertilizers. However, the influence of returning Astragalus sinicus to fields on the soil bacterial communities remains poorly understood. Here, we used the different amounts of Astragalus sinicus partly replace chemical fertilizers and investigated the changes in soil physicochemical factors and the soil bacterial community structure responses.
