GLBRC Research on Bioenergy Crop Sustainability

view full-size image

To improve the sustainability of crops and agricultural residues used for energy production, GLBRC researchers are studying the symbiotic associations of crop roots with arbuscular mycorrhizal (AM) fungi. Interactions with AM fungi benefit host plants by improving the uptake of nutrients, especially phosphorus, nitrogen, and potassium from the soil. Establishing these symbiotic associations in crops grown under suboptimal conditions has the potential to increase biomass production while limiting use of fertilizers and pesticides.
