Data in Context
We are data driven!
At The Russell Ranch Sustainable Agriculture Facility, we collect data on everything we do. Our regular data collection includes water and fertilizer inputs, yield, weather events, pest pressure, soil microbiology, energy use, and more. Every ten years, we take deep soil samples of every plot at Russell Ranch to learn about agriculture's affect on soils all the way to three meters deep. Our data is publicly accessible, and is a growing resource for researchers.
Performing Research at RRSAF
We are a research hub!
Russell Ranch is a hub for public and private researchers, growers, industry professionals, governmental officials, and anyone who wants to come together to learn more about sustainable agriculture. A key part of our mission is to host research projects on the Century Experiment plots, and other ground at Russell Ranch.
