CASI honored with SWCS 2022 Conservation Innovation Award - August 2, 2022
CASI honored with SWCS 2022 Conservation Innovation Award - August 2, 2022
August 4, 2022
California's Conservation Agriculture Systems Innovation (CASI) Center was recognized as the recipient of the 2022 Conservation Innovation Award by the Soil and Water Conservation Society at their Annual Conference held in Denver, CO from July 31 through August 3rd 2022. Tom Willey, retired organic farmer in Madera, CA and long-time CASI member received the award on behalf of our entire group and also presented a summary of work currently being done by a group of California organic farmers on reduced disturbance systems. The 2022 Award recognizes many years of dedicated service that CASI members have provided in extending information and increasing the adoption of improved performance production systems in California since 1998 when the organization was founded. Tom also had the opportunity to meet USDA NRCS national Chief Tom Cosby at the Denver conference and he invited the Chief to meet with CA CIG Project organic farmers when he is coming to the state in September 2022.

Storyteller Douglas Gayeton visits Park Farming and Fully Belly Farm, May 20, 2022

The Lexicon of Sustainability's Gayeton visits Park Farming and Fully Belly Farm
Douglas Gayeyon, storyteller and creative force behind the Lexicon of Sustainability (https://www.thelexicon.org/) spent the better part of May 20, 2022 interviewing and photographing Scott and Brian Park of Park Farming in Meridian, CA and Paul Muller of Full Belly Farming in Guinda, CA as part of a book that he is working on that is going to be about regenerative agriculture. He had been trying to work with the Parks and Muller for quite some time due to the reputations they have for being progressive farmers who have been putting great efforts into further improving their already outstanding farming systems. The Parks, Muller and Andrew Brait at Full Belly are part of a broader group of California farmers who over the past three years have been exploring opportunities for reducing soil disturbance in their organic vegetable production practices. While at Park Farming, Gayeton photographed Park showing a variety of innovative equipment that he has created and acquired over the years, an organic carrot seed production field, a cover crop roller trial, and an elaborate demonstration field where the Parks are evaluating nine different types of reduced disturbance systems for tomato production. With Muller at Full Belly, he photographed Muller in one of his no-tillage fields and also captured images of Muller in an orchard where grazing sheep roam. Gayeton will return to capture additional photos of the Parks' equipment fabrication shop in the near future.

CASI's Mitchell meets with researchers from Rothamsted Research in UK, March 17, 2022
March 20, 2022
CASI's Jeff Mitchell was invited to meet with eight researchers of the Rothamsted Research facility in Great Britain as part of a research exchange program organized by the College of Agriculture and Environmental Sciences at the University of California, Davis along with several other campus researchers on March 17, 2022. Rothamsted Research is the longest-running agricultural research institution in the world. Its foundation dates from 1843. The exchange was hosted by the Global Exchange Office at UC Davis and involved individual presentations and follow-up discussions between UC Davis researchers and the Rothamsted Research visitors. Mitchell was asked to present a discussion on the topic of "Cooperative Extension in California" and shared several aspects of our CASI Center as well as the historical background of Cooperative Extension, the land-grant university, and the agricultural experiment station system in the United States.

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.

Fresno State's Shrestha counts weeds at CIG vegetable farmer's Santa Ana ranch in Hollister, CA!
February 6, 2022
Expert weed ecologist, Dr. Anil Shrestha, of Fresno State's Department of Viticulture and Enology, has begun two exhaustive investigations of weed prevalence and diversity at the organic farm of USDA NRCS CIG Project farmer member, Phil Foster. The study involves four cover crop treatments that include Merced rye, Pacheco triticale, Phil's 'go to' mix of Phacelia, millet and faba bean, and the SJV morning glory suppression mix of Cary Crum that other CIG farmers are also trying at their farms. Each cover crop is laid out in fifteen-foot wide strips that are replicated throughout the field three times. Shrestha took his first set of data on February 3rd at the Santa Ana ranch study site and plans to return in two weeks for additional observations there as well as at Phil's San Juan ranch location where a similar replicated study is underway. Suffice it to say that ample very interesting data will stem from these monitoring efforts and that even in the initial sampling there seemed to be rather striking differences between the cover crops in terms of weed counts. A plot plan of the study that Phil prepared and a short video clip of the sampling methodology used by Dr. Shrestha are provided below. A link to a You Tube link of the video of Dr. Shrestha's sampling technique is provided here as well.
