ISTC’s Wei Zheng will showcase his research project “Designer Biochar to Capture and Recycle Phosphorous from Tile Drainage Systems” at the Illinois Farm Bureau’s Fulton County Field Day on July 16.
Zheng and team have proposed to combine a woodchip bioreactor with designer biochar at the tile drain outlet to capture phosphorus within the biochar. The biochar can be removed from the bioreactor system periodically and spread over the field as a form of slow release phosphorus fertilizer. They predict that the system will prevent excess nutrients from the phosphorus from entering local waterways and, if used throughout Illinois farmlands, will help reduce Illinois nutrient load to the Mississippi River and Gulf of Mexico.
Besides an inside look at Zheng’s research, the Field Day will feature additional research tours on vegetative buffer strips and drainage water recycling at the MWRD site, 15779 County Road 5, Cuba, IL. Registration starts at 11 a.m., followed by the tours from 12:30 to 2 p.m. Attendance is free, and lunch will be provided. Pre-registration is still available by calling the Fulton County Farm Bureau at 309-547-3011 or emailing at email@example.com.
