Overview (from the project web page, see link below)
Biochar has been proposed as a carbon negative soil amendment that can reduce greenhouse gas emissions through a number of mechanisms, one being the mitigation of N2O emissions.
We tested the efficacy of a high temperature (~950°C) walnut shell (WS) and moderate temperature (~550°C) pine chip (PC) biochar applied at 10 tons ha-1 in reducing N2O and CO2 emissions in a Mediterranean commercial wine grape system in California.
Our primary focus was to quantify N2O emissions in this system with the intent of elucidating the mechanisms that drive emissions at a field scale, as well as the management or environmental events that drive annual emissions.
