Biodegradable prebiotic for enhanced nitrogen fixation in cereal crops
A biodegradable prebiotic formulation enhances native nitrogen-fixing bacteria activity in cereal crop rhizospheres, improving nitrogen use efficiency and reducing synthetic fertilizer reliance.
Overview
The biodegradable prebiotic formulation developed by Agribion B.V. is designed to improve nitrogen use efficiency in non-legume cereal crops such as maize and tomato. By selectively boosting the activity of native nitrogen-fixing bacteria in the rhizosphere, this innovation reduces the need for synthetic fertilizers. The formulation provides targeted carbon substrates and micronutrients, enhancing nitrogenase functionality in free-living diazotrophs. This approach supports a sustainable agricultural model, leveraging existing soil microbiomes without leaving persistent residues.
Technical specifications
- Prebiotic Formulation: The solution consists of natural, biodegradable blends (Preb1, Preb3, Preb5) that are applied as a drench to the rhizosphere.
- Mechanism of Action: It delivers carbon substrates and micronutrients that boost native diazotroph activity, enabling them to fix atmospheric nitrogen directly in the root zone.
- Trial Results: Early greenhouse and field trials have shown increases in nif-carrying bacteria and biological nitrogen fixation indicators, suggesting reduced fertilizer needs and improved nitrogen use efficiency.
Technology readiness level
This technology is at TRL 5, having been validated through greenhouse and field trials. Ongoing studies continue to optimize and confirm its efficacy across different environmental conditions.
About Agribion B.V.
Agribion B.V. is an early-stage, Netherlands-based research venture focused on the field of precision microbiome approaches for agriculture. The company explores scientific pathways regarding plant-associated microbiomes to potentially contribute to more stable and sustainable agricultural systems. Their research platform combines microbiology expertise with computational modeling to accelerate discovery and generate foundational insights that complement traditional methods such as breeding and seed technology. As of their latest reporting, Agribion B.V. remains in an exploratory, pre-commercial phase and does not offer commercial products. The company aims to contribute knowledge that may help future innovations address challenges like extreme weather, emerging pathogens, and evolving environmental regulations in farming. By studying how functional microbiomes contribute to plant resilience, their work is designed to explore ways to reduce chemical dependency and support crops under various environmental pressures. The organization operates out of Utrecht as part of the Dutch agricultural research sector.
