20-year summary of soil health research in Five Points, CA published in California Agriculture!

May 17, 2024

Findings from twenty years of soil health research in Five Points, CA have been published in the University of California's California Agriculture peer-reviewed journal's May 1, 2024 issue.  https://doi.org/10.3733/001c.94714. 

This work has been a large collaborative effort involving twenty-one UC and non-UC coauthors.  It began in 1998 initially as an effort to evaluate the potential of reduced disturbance tillage systems to reduce dust emissions from annual cropping systems that are common in California's San Joaquin Valley.  It long-term nature however, allowed it to become a unique site for also monitoring changes in soil properties and function under four experimental systems:  conventional tillage with no cover crop, conventional tillage with cover crop, no-till with no cover crop, and no-till with cover crop.  Crops rotated between tomato and cotton initially, but later during the study, the rotation was diversified to include melons, sorghum, and garbanzo beans.  

The work involved the Soil Health Institute's Shannon Cappellazzi, who sampled at the site in 2019.  That sampling event led to the site becoming part of a multiple-publication series of articles that reported on soil health impacts in 124 long-term study sites across North America.
