CIG's Willey and Foster conducting pressurized air injection study in peppers in Hollister, CA in 2022!
August 13, 2022
The national NRCS Conservation Innovation Grant Program CA organic reduced disturbance vegetable project has a new research component this year at the Hollister, CA farm of Phil Foster. Both he and CIG Project partner, Tom Willey, along with John Petrosso, of the Mazzei Company in Fresno, CA have set up an elaborate trial in one of Foster's 2022 bell pepper fields to test the potential of using pressurized air injection into drip irrigation water as a means of adding oxygen to the crop's root zone. One of the suspected challenges in increasingly reduced soil disturbance production systems is thought to be lack of oxygen and this method may be a means for overcoming this issue. On August 10th, the three of these study partners, along with Jeff Mitchell, met out in the pepper field to take stock of things and to make observations about crop growth and development in the four experimental treatments that Phil has established - reduced till (strip-tillage) without injected air, reduced till (strip-tillage) with air injection, spader-till without injected air, and spader-till with injected air. To date, drone images have not shown striking differences in growth. Phil's harvest is coming up soon and he intends to very carefully weigh each plot's productivity through his several hand harvests. Stay tuned for more conclusive information coming from this innovative approach to vegetable production.

Fresno State weed science students learn about cover crop roller/crimpers March 4, 2022
March 4, 2022
Nearly 100 students in Dr. Anil Shrestha's weed science course at Fresno State University spent time in the field as part of their laboratory sessions to learn about the potential roles that cover crops and roller/crimpers might play in weed management and moreover, improved performance annual crop production paradigms. Although roller/crimpers have been around and used in several places around the world including the South American countries of Brazil, Argentina, and Paraguay, as well as in the Southeast US for decades, the technology is relatively new in California. However, Dr. Shrestha and his MS student, Robert Wilmott, have been evaluating the approach for five years on the CSU Fresno campus with good success and this spring their current study provided a very nice and rich educational opportunity for students to visit and observe.
During the week of February 28 through March 4, three lab sections of Dr. Shrestha's class toured the various cover crop mixes that he and Wilmott have in their study. The students learned about the background of the roller/crimper, its potential use in improved performance production systems that rely on principles of soil health management, and characteristics of the various cover crop treatments that Shrestha and Wilmott are evaluating as part of their ongoing study. Wilmott led each group of students out into the field where they observed the different cover crops and also learned about various weed species that were seen often in bare spots where the cover crops didn't cover the soil.
At the end of the lab, students helped Wilmott and Shrestha by collecting data on the maturity stages of two cover crops, Pacheco triticale and Merced rye, that are part of a multi-site evaluation of two maturity stages for cover crop rolling. Students took data on the percentage of random plants that were at the anthesis or initial flowering stage in the strips where replicated plantings of the two cover crop species were located. Rolling at antheis is one of the roller/crimper timing treatments that Shrestha and Wilmott and a wider group of colleagues in Salinas, Santa Cruz, and Davis are evaluating this spring.

California organic reduced disturbance vegetable farmers to speak April 6, 2021 as part of ECOFARM Workshop
April 6, 2021
Four California organic farmers, Phil Foster of Hollister, Paul Muller of Guinda, Scott Park of Meridian, and Tom Willey of Madera, will participate in an hour-and-a half online workshop session on April 6, 2021 from 12:00 PM through 1:30 PM about the reduced disturbance work that they are conducting as part of an NRCS CIG project aimed at investigating and refining organic reduced disturbance techniques in California. The workshop will feature a Q & A session that follows a panel presentation that the four farmers made as part of the 2021 ECOFARM Conference in January. The workshop will be moderated by CASI Workgroup member, Dr. Cindy Daley of Chico State. An audio summary introduction to the workshop that ran on Don York's "Ag Report" radio program on KMJ580 on April 6th is linked below.

Reduced disturbance innovation at Pinnacle Organics by Phil Foster in Hollister, CA!
May 20, 2020
Folks,
Here is a short 12-minute video update from Phil Foster on some of his recent reduced disturbance and shade cloth work with Tom Willey.
Keep going strong, everyone!
All the best,
Jeff
