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.

Strip-till Operation Thrives in Face of Heavy Regulation and High Costs

Strip-till Operation Thrives in Face of Heavy Regulation and High Costs
Tipton, CA dairyman and long-time CASI farmer member, Tom Barcellos, was featured in the Winter 2023 issue of Strip-till Farmer, a quarterly publication of the National No-till Farmer Association and Lessiter Publications. The article details Tom's 23-year history as a strip-till trailblazer right here in California's San Joaquin Valley and describes how he came to find how strip-tillage "made everything a lot easier" at his 2,000 cow dairy just east of Highway 99 in Tulare County. The Strip-till Farmer magazine article was written by Noah Newman when he came to California recently to interview Tom. A copy of the article is attached below.

Top 15 No-till and Conservation Agriculture Research Articles Selected by Panel at National No-till Farmer Association!
Top 15 No-till and Conservation Agriculture Research Articles Selected by Panel at National No-till Farmer Association!

During the past couple of months, Randall Reeder, retired Extension Agricultural Engineer with the Ohio State University, (and legendary professional speaker who “brings to life the warmth and humor of Will Rogers as he speaks to business and agriculture audiences, and a variety of other groups”), who is also a recognized No-till Research and Education Innovator by the National No-till Farmer Association, and Don Reicosky, retired USDA ARS soil scientist from Morris, MN, who many of you in CA already know from our having hosted him here on at least a couple of occasions in the past (Don is also a past No-till Research and Education Innovator recognized by NNTFA), worked on a survey and compilation of the top 15 research articles of all time in no-till and in conservation agriculture. A committee was created and voting took place to come up with the final lists of works that were announced at the annual meeting of NNTFA last week in Louisville, KY. Both Randall and Don are pretty amazing folks in terms of their decades-long dedicated service to the fields of no-till and conservation agriculture. I think the idea for the lists came from the organizers of the NNTFA and they then asked Randall and Don to coordinate things.
The lists are attached. Perhaps you'll recognize some of the titles as they are pretty well-known and highly respected items.
All the best,

Fresno State agronomy students visit long-term no-tillage study site in Five Points, CA, October 11, 2021
October 11, 2021
Students in the agronomy class of Dr. Ranjiy Riar at Fresno State University had a rare opportunity to visit a working no-tillage research field as part of a field trip that they took to the NRI Project field at the University of California's West Side Research and Extension Center in Five Points, CA. On what was the windiest day of the year, the students braved the uncomfortable and blistering wind to see not only equipment that is used for reduced disturbance production, but also no-till soils and residues, as well as live demonstrations of soil aggregation and water infiltration. Jeff Mitchell of the Conservation Agriculture Systems Innovation Center at UC Davis hosted the group along with fellow CASI members Joy Hollingsworth and Dan Munk.
No-tillage is still very much in its infancy in California, but continuing research by the group in Five Points that includes farmers, university, NRCS and private sector partners has shown that it is possible to produce several annual crops that are part of Central Valley production rotations successfully with the reduced disturbance approach. In addition, the researchers have documented several positive changes in soil properties and function when the combination of no-tillage and cover crops is used consistently over time.
Students in Dr. Riar's class learned about the “3 E's of farming” – equipment, economics, and ecology, during their visit to the field station and they saw no-till drills and planters and strip-tillage implements. They learned how to determine % residue cover over the soil and compared residue cover under no-tillage with cover crops versus standard clean tillage. Dr. Riar mentioned how surprised he was when he first came to California to learn how little of the practice is actually currently used in the state.
Despite the horrendous wind, the field trip was a huge success and gave students much to think about as they carefully drove back to the Fresno State campus.
