CASI's Jeff Mitchell was a "three-peater" July 5th on Tom Willey's "Down on the farm" radio program on KFCF's 88.1 FM station on July 5, 2024. He shared information from the recently published article, No-tillage, surface residue retention, and cover crops improved San Joaquin Valley soil health in the long term, that was published in the May 2024 issue of California Agriculture. Willey was a co-author on the work and he talked with Mitchell about how the work came about, what its study goals were, how it was conducted, and what its findings were. Willey's program airs every first Friday of the month and has a loyal following that includes a great diversity of folks who greatly enjoy his 'on the front porch' conversations with his guests. A video of the radio interview is available at the You Tube link

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.

Robert Willmott not only recently wrapped up his MS thesis research at Fresno State, but he also works full-time as the Farm Manager for his college's student ag farm, is married, and has two small children as well! A full plate, to say the least. In addition to all this, he recently told his story at Fresno State in a 3-minute video that is now posted at You Tube https://www.youtube.com/watch?v=Uo6xZh5sGdA
Working in the Department of Plant Science in the Jordan College of Agricultural Sciences and Technology under his award-winning and Fellow in the American Society of Agronomy major professor, Anil Shrestha, Robert presented his thesis work in an exit seminar on May 14th on campus ahead of being awarded this MS and graduating later this month. His work consisted of a multiple-year study to evaluate the potential of using a roller crimper and strip-tillage for producing silage corn under center pivot irrigation, a new systems approach for San Joaquin Valley dairies that rely on winter and corn silage for animal feed materials. The several years of the study saw quite good success in terminating a variety of winter cover crop mixes using the roller crimper, strong weed suppression during the early corn season, and corn yields comparable to industry standards and the conventional control system that was part of the evaluation.
The work is now being prepared for submission to a scientific journal later this summer. A three-minute You Tube video summarizing Robert's work may be viewed at the link https://www.youtube.com/watch?v=Uo6xZh5sGdA

Documentary video on no-tillage in California being prepared
July 1, 2023
A video documentary featuring five of the CA and AZ farmers who have been part of the USDA NRCS Conservation Innovation Grant project, "No-till network for California," is in the final stages of production and will be released in the near future through the University of California's Conservation Agriculture Systems Innovation Center's You Tube channel.
https://www.youtube.com/channel/UCVd3wKF3P6fA4zQWVKIouWA
The documentary will feature Eddie Sajian of Hanford, CA, Rick Adams of Laton, Paul Strojan of Farmington, Dr. Henri Carter MD of Yuma, AZ, and Cary Crum, of Fresno, CA and will show them describing details of the innovative approaches that they are working on to improve the overall performance of their agricultural production systems. The release date for the documentary is scheduled for late July 2023.
