1. Introduction Plant-soil feedbacks affect community composition, nutrient cycling, and plant development, all of which are critical factors in determining the dynamics of an ecosystem. Depending on the species involved, these complex interactions between soil microorganisms and plants can either improve or worsen plant performance. Clovers, or Trifolium species, are well-known for their capacity to fix nitrogen and increase soil fertility. Trifolium species have the ability to affect local...
