Soil Homogenization Modifies Productivity, Nitrogen Retention and Decomposition in Restored Grassland

At the local (within site) scale, soil heterogeneity can influence ecosystem function. However, in former agricultural systems, soil heterogeneity can be low as a legacy of tillage (that is, via the process of soil homogenization). We investigated the relationship between soil homogenization and three ecosystem functional response variables—aboveground productivity, nitrogen retention (assessed via 15N tracer addition) and plant litter...
