Abstract

   Plants can change soil biology, chemistry and structure in ways that alter
   subsequent plant growth. This process, referred to as plant-soil feedback (PSF),
   has been suggested to provide mechanisms for plant diversity, succession and
   invasion. Here we use three meta-analytical models: a mixed model and two Bayes
   models, one correcting for sampling dependence and one correcting for sampling
   and hierarchical dependence (delta-splitting model) to test these hypotheses. All
   three models showed that PSFs have medium to large negative effects on plant
   growth, and especially grass growth, the life form for which we had the most
   data. This supports the hypothesis that PSFs, through negative frequency
   dependence, maintain plant diversity, especially in grasslands. PSFs were also
   large and negative for annuals and natives, but the delta-splitting model
   indicated that more studies are needed for these results to be conclusive. Our
   results support the hypotheses that PSFs encourage successional replacements and
   plant invasions. Most studies were performed using monocultures of grassland
   species in greenhouse conditions. Future research should examine PSFs in plant
   communities, non-grassland systems and field conditions.
