Succession of bacterial community composition in coastal agricultural soils along a 1000-year reclamation chronosequence in Hangzhou Bay, China

Soil bacterial successional trajectories under frequently disturbed circumstances (such as agricultural practice) are less known due to the complexity and uncertainty of disturbance. Here, a reclaimed coastal soil chronosequence spanning over a millennium was studied to understand the variation in s...
