ROLE OF BIOFERTILIZERS IN IMPROVING SOIL HEALTH AND SUSTAINABLE AGRICULTURE
Soil Health
Sprinkling a mycorrhizal inoculant into your planting hole does the same thing industrial agriculture is now racing to bottle: it wires your vegetable roots into a living nutrient network that keeps feeding plants long after the bag is empty.
Certain bacteria and fungi naturally live in soil and help plants get the nutrients they need — things like nitrogen from the air or phosphorus locked in rock particles. Scientists are studying how to harness these microbes as 'living fertilizers' that boost plant growth without the pollution and soil damage caused by chemical fertilizers. The findings suggest that swapping even part of our synthetic fertilizer use for these microbial helpers could grow more food while keeping soil and waterways healthier.
Key Findings
Biofertilizers improve nutrient uptake through at least four distinct mechanisms: nitrogen fixation, phosphate solubilization, potassium mobilization, and organic matter decomposition.
Key microbial groups include nitrogen-fixing bacteria (Rhizobium, Azospirillum, Azotobacter), phosphate- and potassium-solubilizing organisms, sulfur and zinc mobilizers, mycorrhizal fungi, and decomposers such as Trichoderma.
Biofertilizer application has been shown to improve root development, crop yield, and plant resilience to abiotic stress, while reducing reliance on synthetic fertilizers that contribute to soil degradation, water pollution, and greenhouse gas emissions.

Beneficial soil microbes — including bacteria that fix nitrogen and fungi that help roots absorb phosphorus — can replace or reduce synthetic fertilizers while improving soil health and crop yields. This review outlines how integrating these living inoculants into farming offers a sustainable path forward as global food demand grows.

Mycorrhizal networks are underground fungal systems that connect plant roots together, forming symbiotic relationships where fungi provide essential nutrients and water in exchange for sugars produced by photosynthesis. These networks fundamentally reshape how plants acquire resources and interact
