Assessing the impact of biochar amendment on greenhouse gas emissions, soil fertility, and yield in a commercial vineyard of the Lodi region

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.

    Hmm is anyone else experiencing problems with the images on this blog loading?
    I’m trying to determine if its a problem on my end or if it’s the
    blog. Any feed-back would be greatly appreciated.
