Results obtained under controlled laboratory and greenhouse conditions frequently exhibit limited reproducibility under field environments. Gnotobiotic and sterile experimental systems oversimplify ecological complexity by ignoring interspecies competition and native microbial communities. Environmental heterogeneity, varying climatic factors, soil physicochemical variability, and complex native microbial interactions limit the wider applicability of experimental results.
