Understand what happens around the root.
Nitrogen fixation, nutrient mobilization and micronutrient supply are different processes. Their contribution depends on the growing system.
Biological nitrogen fixation
Nitrogen-fixing microorganisms can convert atmospheric nitrogen into reduced forms. Availability to the crop depends on biological activity and subsequent soil processes; the product does not directly guarantee a fixed amount of nitrogen for every hectare.
- Atmospheric nitrogen
- Root-zone bacteria
- Reduced nitrogen forms
Mobilization of existing nutrients
Mobilizing organisms can influence the availability of phosphorus and potassium already present in the root environment. Their activity does not create these elements or prove that all mineral fertilizer can be removed.
- Existing nutrient pools
- Rhizosphere processes
- More accessible forms
Macro- and micronutrient supply
Nutrient complexes supply their listed elements as part of a crop programme. The right composition and application depend on the crop, growth stage and measured conditions; they are not interchangeable with microbial formulations.
- Measured crop requirements
- Specified nutrient formulation
- Stage-specific nutrition
The environment is part of the programme.
Moisture, temperature, pH, nutrient reserves, crop development and management can affect the context in which a product is used. The global map provides reference information; a field or water test provides a more specific measurement.
A greenhouse can use soil or a nutrient solution. Aquaponics also includes fish and a biofilter. A field-soil explanation does not establish suitability in either system.
