The California Department of Water Resources (DWR) is working to increase agricultural water use efficiency here in California. DWR is funding our research on the effect of biochar and compost on crop water usage. We have set up three research sites:
The first is at the Desert Research and Extension Center in Holtville, CA. Biochar from Cool Planet was applied at different rates. The field is currently laying fallow for the summer but sugar beets will be planted in a few months.
The second site is at Monterey Pacific in King City, CA. Biochar from Pacific Biochar was applied with compost then planted as a Pinot Noir vineyard.
The last is Terra Nova Ranch in Helm, CA. Biochar from Pacific Biochar and chicken litter were applied. Processing tomatoes are planted in this field. Watermark Sensors from Irrometer were installed at 1 and 2 foot depths in each of the plots.
