Multifunctional microbiome augmentation for enhanced nitrogen use efficiency
Innovative microbiome-based solution to improve nitrogen use efficiency by leveraging multifunctional bacterial consortia for enhanced soil ammonium retention and plant growth.
Overview
This groundbreaking solution leverages microbiome-based strategies to improve nitrogen use efficiency in agriculture. By utilizing multifunctional bacterial consortia, this approach aims to enhance soil ammonium retention, thereby reducing the reliance on synthetic nitrogen fertilizers. The technology focuses on the biological processes of dissimilatory nitrate reduction to ammonium (DNRA) and biological nitrogen fixation (BNF) to expand soil ammonium pools, which are less prone to loss than nitrate. This innovative method promises to boost plant growth and productivity sustainably.
Technical specifications
- Multifunctional Consortia: Composed of selected bacterial isolates carrying nifH and nrfA genes enabling DNRA and BNF.
- Greenhouse Validation: Initial testing involves bioaugmentation in controlled greenhouse settings with quantification of effects on plant-available nitrogen, microbiome structure, and plant biomass.
- Molecular Profiling: Utilizes SYBR Green qPCR/RT-qPCR to track the growth, survival, and expression of the consortia.
- Delivery Methods: Investigates various methods (no inoculum, seed-zone, bulk-soil) to determine optimal consortia application technique.
Technology readiness level
This solution is at TRL 3, with ongoing greenhouse validation to prepare for subsequent field trials. The research is focused on developing and testing the efficacy of the DNRA-BNF consortia under controlled conditions to ensure robustness and effectiveness prior to commercial deployment.
