Nitrosomonadales

It is important to clarify that Nitrosomonadales are not plant diseases or pathogens. They are a taxonomic order of Gram-negative bacteria that perform a vital function in the global nitrogen cycle, specifically the oxidation of ammonia into nitrites.

These organisms are considered highly beneficial in agronomy. They act as essential mediators in the process of nitrification, which converts nitrogen from inorganic fertilizers into forms that plants can efficiently absorb through their roots for biomass production.

All agricultural crops benefit from the presence of these bacteria in the rhizosphere. By maintaining the flow of nitrogen, Nitrosomonadales ensure that nutrient uptake remains consistent, promoting better crop yield and quality in various soil types.

The development of these populations depends on specific environmental factors. They thrive in aerobic conditions with sufficient oxygen supply, moderate temperatures, and a neutral or slightly alkaline pH. Soils that are excessively acidic or compacted limit their metabolic activity.

Rather than seeking control measures, farmers should focus on soil conservation practices to support these bacteria.

• Maintaining optimal soil pH through lime application
• Avoiding soil compaction to ensure aeration
• Judicious use of nitrogen fertilizers to support the natural soil microflora
