Ancient microbiome consortiums for enhanced nitrogen uptake in non-legumes
Harness ancient soil microbiomes to boost nitrogen uptake in non-leguminous plants using novel bacterial strains. This technology reduces dependency on synthetic fertilizers by leveraging strains MH1 and MH2 to enhance plant growth under nitrogen-limited conditions.
Overview
This innovative solution leverages ancient microbiomes to enhance nitrogen uptake in non-leguminous plants, specifically using novel bacterial strains MH1 and MH2. These strains are applied to the root interface to stimulate the recruitment of plant growth-promoting rhizobacteria (PGPR) under nitrogen-limited conditions. This approach not only promotes plant growth but also reduces reliance on synthetic nitrogen fertilizers, aligning with sustainable agricultural practices.
Technical specifications
- The method involves the application of bacterial strains MH1 and MH2 to the soil, enhancing plant growth by facilitating the recruitment of PGPR.
- Strains are isolated from ancient soils, rich in nifH, amoA, and nosZ genes associated with biological nitrogen fixation.
- Validated in both greenhouse and field trials, showing improved plant growth and reduced fertilizer needs.
- Future studies will focus on corn and tomato, measuring nitrogen-cycling gene expression, enzyme activities, and nutrient content.
Technology readiness level
This technology is currently at TRL 5, having been validated in relevant environments through both greenhouse and field trials. Further validation is planned to refine the application and expand its use across various crops under low-nitrogen conditions.
