Prairie microbe teams with biodegradable polymer carrier for enhanced NUE
Innovative prairie-derived microbial consortia paired with a biodegradable polymer carrier improve nitrogen use efficiency (NUE) by enhancing root depth, moisture retention, and nutrient assimilation. This solution integrates seamlessly with current farming practices and reduces nitrogen losses.
Overview
Earnest Agriculture presents a cutting-edge solution to optimize nitrogen use efficiency (NUE) using prairie-derived microbial consortia. These "microbe teams" are designed to be applied as seed treatment, in-furrow, or foliar applications, supported by a biodegradable polymer carrier. This carrier boosts the survival and adhesion of the microbes near fertilizer bands, enhancing their effectiveness. The technology aims to deepen root systems, form moisture-retaining extracellular polymeric substances (EPS), enhance ammonium capture, and accelerate urea assimilation. By co-mobilizing phosphorus, it helps maintain crop yield and quality at lower nitrogen rates, contributing to sustainable agriculture practices.
Technical specifications
- Biodegradable Carrier: Utilizes food-grade biopolymers such as alginate, chitosan, and lignosulfonate, ensuring no persistent residues in the environment.
- Microbial Functions: Includes EPS formation for moisture and nutrient capture, ACC-deaminase for stress relief, and organic-acid production for phosphorus mobilization.
- Application Compatibility: Seamlessly integrates with existing farm workflows and cooperative blending, labeled as a state biostimulant.
- Performance Metrics: Proven through greenhouse and field trials with metrics such as biomass, yield, root mass, nitrogen recovery, and reduced leachate nitrate.
Technology readiness level
This innovative solution has reached Technology Readiness Level (TRL) 9, indicating it is fully developed and ready for commercial deployment. It has been validated across multiple sites and conditions, demonstrating non-inferiority at reduced nitrogen levels and significant reductions in nitrate leaching and nitrous oxide emissions.
About Earnest Agriculture
Earnest Agriculture is an agricultural biotechnology company that develops microbial-based farm inputs designed to enhance crop productivity and soil health. Founded in 2018 and headquartered in Rantoul, Illinois, the company utilizes a proprietary platform that employs phenotyping, sequencing, and algorithms to identify and isolate beneficial bacteria from native prairie ecosystems. These microbes are formulated into seed coatings and other delivery systems that provide multiple modes of action, such as improved nutrient use efficiency, better root development, and enhanced stress tolerance. Unlike conventional biologicals that often rely on single-strain or genetically modified organisms, the company's approach focuses on synergistic microbial consortiums designed to remain stable and effective in diverse real-world farming environments.
The company’s solutions are intended to help farmers increase yields while reducing reliance on chemical inputs, addressing challenges such as declining soil health and rising production costs. Their flagship product, Prairie Power Soybean, has demonstrated consistent yield improvements in multi-state field trials. Earnest Agriculture partners with seed developers, ag retailers, and research institutions to integrate its technology into existing agricultural workflows. By prioritizing rigorous, side-by-side field testing, the company aims to provide practical, scalable tools that improve farm resilience and productivity. They continue to expand their product pipeline, which includes offerings for corn and other crops, supported by a network of agricultural stakeholders and research organizations.
