AH11006 - Carbon Amelioration in Horticulture

Biochar is a new, high-carbon soil amendment that has shown promise in improving soil properties and increasing yields in crops around the world. Biochar is created by heating organic biomass, such as chipped tree prunings, garden waste, chicken manure, rice husks and other agricultural by-products at high temperatures and with no oxygen. Preliminary research into biochar application to soil has found improvements to soil structure, fertiliser and water efficiency. Biochar increases soil carbon immediately after addition, and studies have estimated that biochar will remain in soil for hundreds of years.
