Phosphorus-Binding Biochar Helps Prevent Nutrient Pollution
Scientists at the University of Illinois Urbana-Champaign created a custom form of biochar designed to capture phosphorus from farm runoff to prevent waterway pollution. They created “designer” biochar with significantly higher phosphorus-binding capacity than regular biochar by slowly burning pellets made from waste sawdust and lime sludge, a byproduct of drinking water treatment. The pellets […]
