Bioinoculants to increase crop nutrient density and reduce nitrate leaching
Microbial bioinoculant formulations designed to enhance soil biodiversity and improve crop nutrient uptake of calcium and zinc while reducing nitrate leaching. Built from locally sourced effective microorganisms, these inoculants support sustainable agriculture through improved soil health and plant nutrition.
Overview
This solution offers microbial bioinoculant formulations developed to enhance soil health and crop nutrition. The product line includes two complementary formulations: LEM (Locally Effective Microorganisms), a diverse consortium of photosynthesizing bacteria, lactic acid bacteria, yeasts, actinomycetes, and fermenting fungi; and FLEM (false-LEM), which contains lactic acid bacteria, yeasts, and fermenting fungi. Together, these inoculants aim to increase soil microbial biodiversity and functional redundancy, supporting improved plant-available nutrients and reducing environmental nitrogen loss.
The bioinoculants work through multiple mechanisms, including phosphate solubilization, associative nitrogen fixation, mineralization, and phytosiderophore production. By enriching the soil microbiome, the formulations are designed to improve the uptake of key nutrients such as nitrogen, phosphorus, calcium, magnesium, and zinc, while also reducing nitrate leaching into groundwater. Benefits may vary depending on crop type and growing conditions.
Technical specifications
Key features:
- Microbial consortium approach: Combines multiple functional groups of beneficial microorganisms to enhance soil biodiversity and functional redundancy
- Targeted nutrient enhancement: Supports increased plant availability of nitrogen, phosphorus, calcium, magnesium, and zinc
- Improved crop nutrient density: Specifically designed to increase calcium and zinc concentration in harvested crops
- Reduced nitrate leaching: Aims to minimize nitrogen loss to the environment through improved soil microbial function
- Multiple modes of action: Includes phosphate solubilization, associative nitrogen fixation, mineralization, and phytosiderophore production
- Locally sourced organisms: LEM formulation uses locally adapted microorganisms for regional relevance
- Crop flexibility: Applicable across various crop systems, with effects varying by crop type
Technology readiness level
The bioinoculants are at an early-to-mid stage of development. Preliminary research with wheat has produced mixed results in reducing ammonium, nitrite, and nitrate concentrations, with outcomes depending on the specific bioinoculant used, fertilization method, and timing of leaching events after application. Prior published work has demonstrated the potential of these microbial groups to improve plant health and nutrient density. Further validation is needed to optimize formulations, application protocols, and crop-specific performance before broader commercial deployment.
About University of Georgia
The University of Georgia is a comprehensive public land‑grant research university serving a large student body across multiple campuses, known for applied scholarship and community partnership. Industry partners access core facilities and pilot‑scale capabilities—including the Food Product Innovation and Commercialization Center—for prototyping, scale‑up, and product validation. A downtown Innovation District and a statewide Cooperative Extension network link campus expertise to companies across Georgia, while proximity to Atlanta’s corporate and logistics hubs lowers barriers to engagement. Research is supported by competitive federal funding from agencies such as NIH, NSF, USDA, and DOE. A dedicated technology transfer office provides IP services, licensing, startup support, and incubator space to accelerate commercialization.
