Nitrogen-Max is a microbial agent series powered by dual-core biological nitrogen fixation and microbial urease inhibition technologies. Through active microorganisms, it increases soil-available nitrogen from the source, slows chemical nitrogen loss, improves fertilizer efficiency, enhances soil health, supports crop growth and quality, and strengthens crop stress resistance.

Biological Nitrogen Fixation Technology
The product uses highly efficient ammonium-tolerant and ammonium-releasing associative nitrogen-fixing strains, such as Bacillus amyloliquefaciens, to convert free nitrogen gas (N₂) in the air into ammonium nitrogen (NH₄⁺), which can be directly absorbed by plants. The converted nitrogen is then released into the rhizosphere, effectively “manufacturing” nitrogen fertilizer for crops.
Microbial Urease Inhibition Technology
Specific microbial strains, such as Brevibacillus laterosporus, produce urease-inhibiting proteins that effectively reduce soil urease activity. This slows the decomposition of urea applied to the soil, reduces nitrogen loss through ammonia volatilization, and supports longer-lasting slow-release nitrogen fertilizer performance.
Bilan Bio owns core strains with fully independent intellectual property rights, forming the powerful “biological chip” behind Nitrogen-Max.
Bacillus amyloliquefaciens
The core nitrogen-fixing strain, with both growth-promoting and biocontrol functions.
Bacillus subtilis
Promotes nitrogen transformation, phosphorus solubilization and soil activation.
Bacillus megaterium / Priestia megaterium
Supports carbon fixation, phosphorus and potassium solubilization, and soil improvement.
Brevibacillus laterosporus
A patented urease-inhibitor-producing strain that helps improve nitrogen absorption efficiency.
Other Supporting Strains
Includes Bacillus licheniformis for phosphorus solubilization, Bacillus velezensis for growth promotion, nitrifying bacteria, stress-resistant nitrogen-fixing bacteria and other functional strains.
The product is supported by nine core invention patents as of the manual publication date, covering multiple technical fields such as growth promotion and disease resistance, nitrogen fixation, urease inhibition, carbon fixation and compound microbial agents. This ensures the product’s technological originality and reliable performance.
Biological nitrogen fixation supplements available nitrogen, while urease inhibition reduces nitrogen fertilizer loss. In practical applications, chemical nitrogen fertilizer use can be reduced by 30% or more depending on field conditions and application plans, while fertilizer utilization efficiency is significantly improved.
The strains secrete extracellular polysaccharides that improve soil aggregate structure. The base-fertilizer type additionally supplements ≥30% organic matter, such as humic acid, helping relieve soil compaction and improve soil fertility from the root. User feedback also shows continued soil improvement effects for the following crop.
Functional strains help suppress soil-borne pathogens and reduce disease occurrence. They also enhance crop tolerance to drought, saline-alkali stress and other adverse conditions. Field cases in saline-alkali soils in Tianjin showed significant promotion of root development.
The product provides balanced nutrition, promotes crop growth and development, increases dry matter accumulation, and improves both yield and quality, such as higher starch content in potatoes.
Under severe drought conditions, crops treated with Nitrogen-Max showed more expanded leaves and less leaf curling, helping users reduce irrigation pressure and save irrigation costs.
The product is suitable for field crops such as corn, rice, wheat and soybean, as well as cash crops such as potatoes and vegetables. Its performance is stable across different crop systems.
Nitrogen-Max is not a traditional fertilizer additive, but an integrated solution for soil ecology and crop nutrition. It is built on independently patented microbial strains and powered by the dual-core technology of “nitrogen fixation + urease inhibition.”
