Mycorrhizal fungi and slow-release fertilizer for enhanced carbon sequestration in lawns
This innovative approach utilizes arbuscular mycorrhizal fungi (AMF) with slow-release nitrogen fertilizers to boost turfgrass root growth and increase carbon sequestration in soil. This solution aids in climate resilience, reducing CO2 emissions and supporting sustainable lawn management.
Overview
Our research focuses on leveraging arbuscular mycorrhizal fungi (AMF) inoculants in combination with slow-release nitrogen fertilizers to enhance turfgrass root development and soil carbon sequestration. This innovative method not only boosts turf biomass and improves soil structure but also reduces CO2 emissions, contributing to climate resilience. The integration of AMF can transform conventional lawn management into an environmentally responsible practice that supports biodiversity and offers cost savings for homeowners.
Technical specifications
- AMF Inoculation: Enhances root growth, nutrient uptake, and drought tolerance, increasing carbon inputs into soil organic matter.
- Glomalin Production: Produced by AMF, glomalin stabilizes soil carbon by enhancing soil aggregation and protecting organic matter.
- 13C Isotope Labeling: Used to track carbon flow from plants to soil, demonstrating increased carbon retention and stabilization.
- Slow-release Nitrogen Fertilizer: Optimizes nutrient availability, supporting healthy turfgrass growth and reducing the need for frequent applications.
Technology readiness level
Currently at TRL 5, this technology has been validated in real-lawn studies, confirming the benefits of AMF in reducing soil CO2 emissions and enhancing turfgrass growth. Further validation will occur through controlled greenhouse and growth chamber experiments, focusing on long-term effects and practical implementation strategies for homeowners.
