Scientist seeks to capture, recycle phosphorus from tile drainage

ISTC researcher Wei Zheng recently received a grant from the┬áIllinois Nutrient Research and Education Council (NREC) to develop specially designed biochar to capture and recycle phosphorus. Read FarmWeek’s story about the project here.

Specially designed biochar, seen lower right, would absorb phosphorus from tile drainage water filtered by a woodchip bioreactor. ISTC researcher Wei Zheng is studying special biochar as a water filter, which could be used as slow-release fertilizer. (Illustration by Wei Zheng, ISTC)
