Abstract:Aims
Soil biotic legacies of leys in grassland-crop rotation systems affect growth of subsequent crops and are garnering increasing attention. We studied how different grass and legume species grown in monoculture or mixture affect the growth of the subsequent maize crop and whether the legacy effects depend on external phosphorus inputs.
Methods
We collected microbial inoculum from a five-year experiment with nine leys, including monocultures of two grasses and two legumes, and five legume-grass mixtures in… Show more
