Plant-soil feedback responses of four dryland crop species under greenhouse conditions.

ABSTRACT: Plant-soil feedbacks (PSFs) give a mechanistic understanding on how soil properties established by previous plant species go on to influence the performance of the same or different species in monoculture, intercropping or crop rotation systems. We hypothesized that different dryland crops such as Zea mays L., Helianthus annuus L., Phaseolus vulgaris L., and Glycine max L. (Merr.) will have soil legacies that are related to the crop type. We used a two-phase experiment to test plant performance in soils previously cultivated with the same or different plant species under greenhouse conditions. The positive plant growth for all species in their own soil microbiota suggests that mutualists had a greater impact on plant performance than pathogens. The consistent po
