Great to see this opportunity for RegenPGC Graduate Education Community member Ralph Danquah-Acquah to present his poster, Green between the rows: modeling Corn-RhB perennial ground cover systems,” at th at the 2026 Iowa Water Environment Association Annual Conference in Des Moines.* Click here Ralph’s poster.
Ralph’s poster presentation shared his graduate research where, working with his advisor, RegenPGC CoPd Dr. Amy Kaleita, he uses the ALMANAC Simulation Model to evaluate corn-RHb perennial groundcover systems as part of the RegenPGC project. According to Ralph, “Perennial groundcover systems offer a promising way to reduce runoff and soil erosion while maintaining corn production. My work uses the ALMANAC model to compare PGC with conventional and strip tillage systems, with a focus on soil water dynamics, surface runoff, soil erosion, and corn yield performance under different rainfall conditions.”
Overall, Ralph’s work focuses on soil water dynamics, surface runoff, soil erosion, and corn yield performance under perennial groundcover systems.
