Microalgae and Plant Growth Promoting Rhizobacteria for Sustainable Agriculture: Biostimulants and Biofertilizers to Improve Soil Health and Plant Stress Resilience.

Soil Health
Swapping synthetic fertilizers for microbial blends in your vegetable beds could rebuild the living soil chemistry that chemical inputs have been quietly eroding for decades.
Tiny organisms — helpful soil bacteria and microalgae — can act like a natural fertilizer, producing vitamins, growth hormones, and other compounds that feed plants and help them handle drought or disease. Scientists found that mixing these two types of organisms together works even better than using either one alone. This opens the door to farming and gardening practices that build up soil instead of wearing it down.
Key Findings
Microalgae and plant growth-promoting soil bacteria each independently improve soil fertility by naturally producing amino acids, pigments, plant hormones, and vitamins.
Combined microalgae-bacteria cocultures outperform either organism used individually as biostimulants, due to synergistic interactions.
These biological alternatives enhance plant resilience to environmental stresses while avoiding the ecological damage associated with chemical fertilizers.

Combining soil bacteria and microalgae as natural fertilizer alternatives can boost plant growth and stress tolerance better than either used alone, offering a path away from chemical fertilizers that degrade soil over time.
