Theory of microbial coexistence in promoting soil–plant ecosystem health

A healthy soil plant continuum is critical for maintaining agroecosystem functions and ensuring food security, which the basis of sustainable agricultural development. Diverse microorganisms form a complex assembly play an important role in agroecosystems by regulating nutrient cycling, promoting growth, alleviating biotic abiotic stresses. Improving microbial coexistence may be effective practical solution promotion soil–plant ecosystem health face impacts anthropogenic activities global climate change. Modern theory useful theoretical framework studying species that are competing resources. Here, we briefly introduce basic modern theory, including definitions mathematical calculations niche difference fitness difference, as well ways to test these differences empirically. The possible effects several major factors, such biological interactions, change, environmental stress, fertilization, on discussed. From perspective stabilizing equalizing mechanisms, potential roles microbe–microbe interactions plant–microbe soil–microbe–plant presented. We suggest use design construction communities production can provide solid improvement agroecosystems.
