Why the market continues to grow

Industry data indicate that China’s microbial fertilizer market grew from RMB 29.92 billion in 2014 to RMB 44.06 billion in 2022, an average annual increase of about 5%. Market forecasts suggest that the domestic market could exceed RMB 60 billion by 2027 if growth remains near 7%.

Demand is supported by fertilizer-use efficiency, soil health, saline-alkali land recovery, continuous-cropping management and crop-quality improvement. Microbial fertilizers are now used in vegetables, fruit, tea, medicinal crops and broadacre production.

Three main microbial fertilizer categories

China’s registration system mainly covers agricultural microbial inoculants, bio-organic fertilizers and compound microbial fertilizers. Of 1,959 fertilizer registrations approved in 2024, 1,281 were microbial fertilizers. From January through April 2025, microbial fertilizers represented 432 of 671 approvals.

Fast registration growth shows strong activity, but registration, labelled viable counts and packaging claims do not independently prove field performance. Strain selection, fermentation, storage stability, carrier quality and application environment all matter.

Competition shifts toward field performance

The market is moving from single-product competition toward technical systems and crop programs. Strong suppliers need strain preservation, propagation, manufacturing, quality control and application support, with recommendations matched to soil, crop and growth stage.

Key development areas include phosphate-solubilizing, nitrogen-fixing, growth-promoting, composting, stress-tolerant and soil-remediation microorganisms. Buyers should evaluate viable-cell stability, contamination control, environmental adaptability and repeated field results.

Salt-tolerant bacteria gain importance

High salinity, alkalinity and osmotic stress can reduce survival and colonization of ordinary strains. Salt-tolerant bacteria are valuable because they can remain active in difficult rhizosphere conditions and support microbial balance, root-zone recovery and nutrient use.

Ihumate Agropha G31A and Agropha G31B are salt-tolerant bacteria. Nematicidal Max and Nematicidal Plus use Agropha G31A in integrated programs for nematode pressure, salinity stress and rhizosphere improvement. Salt-tolerant bacteria work best with organic carbon, humic substances, soil-structure management and suitable irrigation.

How to select microbial fertilizers

  • Define the problem: distinguish salinity, compaction, continuous cropping, weak roots, nutrient fixation and soil-borne disease.
  • Match strain function: confirm that the strain addresses the target problem instead of comparing total counts alone.
  • Check stability: review shelf life, storage, carrier, contamination control and batch consistency.
  • Match application conditions: avoid simultaneous use with strong bactericides and consider moisture, temperature and organic matter.
  • Run a local trial: compare root growth, soil EC, crop vigor, yield and quality before scaling up.
