This paper investigates how microbial consortia, which include a combination of plant growth-promoting bacteria, mycorrhizal fungi, and other beneficial microorganisms, contribute to enhanced plant growth. The study covers a detailed examination of the impact of microbial consortia on nutrient uptake, plant stress tolerance, and biomass accumulation in various crops. It also explores the synergistic interactions within the microbial consortia that result in improved agricultural productivity and reduced reliance on chemical inputs.
