August 29, 2018 

CASI's John Diener of Five Points to be featured in "Stories of the Soil" video by Cool Planet and the Future of Agriculture Podcast with Tim Hammerich!
John Diener of Red Rock Ranch in Five Points, CA was extensively interviewed at his farm on August 29th by a video group from Cool Planet and the Future of Agriculture Podcast about his long-term soil care practices and experiences.  The interview will soon be featured as part of a series called “Stories from the Soil.”  For many years, John has been working to develop techniques to care for his soil at Red Rock Ranch and he shared his experiences with the video crew during the two-hour shoot.  The group also visited CASI's NRI Project field where UC Davis graduate student, Geoff Koch, had a chance to listen in and learn from John's vast, cutting-edge experience.  Stay tuned for information about the release of this video!

CASI hosts no-till pioneer, Francis Akolbila, of Ghana's Center for No-till Agriculture!

CASI hosts no-till pioneer, Francis Akolbila, of Ghana's Center for No-till Agriculture!

August 27 – 28, 2018


A number of CASI Workgoup members graciously hosted a true pioneer in no-tillage conservation agriculture systems, Francis Akolbila of the Center for No-till Agriculture in Ghana ( this past week at their farms here in California.  Francis is a dynamic, very passionate and dedicated leader of conservation agriculture in Africa.  He is in California for an 6-month internship that he will soon be completing at Singing Frogs Farm in Sebastopol, CA with Paul and Elizabeth Kaiser before moving on to spend two months this fall at the Dakota Lakes Research Farm with Dwayne Beck in Pierre, SD.  It was a pleasure and great honor for many of us to host him and we had great interactions with him in what turned out to be a whirlwind set of visits throughout California's Central Valley.

Francis first had a chance to meet and talk with local UC Cooperative Extension Soil and Water Advisor, Dan Munk, along with NRCS Fresno Area Conservationists Brook Gale and Rob Roy, for a lunch discussion at the legendary Five Points, CA “El Ranchero Café”  (Figures 1 and 2).  He explained what the Center for No-till Agriculture does and he shared with the group how it developed from the vision of Director Kofi Boa and with the support of the Howard Buffett Foundation.

 Following this very nice visit with local Fresno County folks, Francis toured the longstanding NRI no-till project in Five Points where he saw up close and personal our Workgroup's research and development work with no-till systems (Figure 3).  He also had a very nice opportunity to ride in a tractor with field station no-till expert, Jaime Solorio, and he learned about GPS guidance systems that were being used for the project's tillage work in the standard, conventional high disturbance tillage systems (Figure 4).

Francis was then hosted by Jesse Sanchez of Sano Farms out in Firebaugh, CA.  While there, he saw Jesse and Alan Sano's cover crop fields and he learned how they extract drip tape from fields after seven or eight years of use.  He also had the opportunity to learn how Jesse is now using a new fixed-wing drone to help with field management and irrigation at Sano Farms (Figures 5 and 6).

Next, Francis headed up to the Madera, CA farm of Tom and Denesse Willey, where he met with Tom and Madera County NRCS Conservationist, Priscilla Baker (Figure 7).  While there, Francis learned of the reduced disturbance work that Tom is planning as part of the new NRCS Conservation Innovation Grant project that he's involved in with a group of pioneering reduced disturbance farmers throughout California.  Francis, Tom and Priscilla also discussed cover crop options and how they're being used to good effect in Ghana.

Very early the next morning, Francis made the trek up to Turlock, CA where he met with long-time no-tillers, father and son farming team, Michael and Adam Crowell, at Bar Vee Dairy (Figure 8).

There, Michael and Adam showed Francis their recently-planted double-crop no-till corn crop and the three of them talked at good length about no-till equipment and techniques (Figure 9).  The visit was not complete without Michael getting down on his hands and knees and showing Francis his soil (Figures 10 and 11).

 Finally, Francis had a chance to stop by the PLS110 vegetable production class field laboratory on the University of California, Davis campus for a short visit with field Jim Jackson, Rich Peltzer, and Derrick Lum of the University's Department of Plant Sciences (Figure 12).  He learned about the field prep work that these guys are doing to get ready for the fall class that will evaluate aspects of conservation agriculture systems in their cropping systems comparison demonstration field.

CASI was honored to host Francis Akolbila this past week and we wish him all the very best as he now completes his internship and returns to Ghana for his very important and pioneering work with conservation agriculture systems there with Kofi Boa.  We thank Dwayne Beck for encouraging this meeting with Francis and we look forward to staying in touch with him into the future!

Managing Soil Health for Sustainable Agriculture

Managing Soil Health for Sustainable Agriculture

“Managing soil health for sustainable agriculture covers virtually the entire range of soil health topics. Dr Don Reicosky, himself an internationally distinguished soil scientist, has assembled an impressive roster of chapter authors. Each is a world-class specialist in the topic of the chapter. This collection of diverse chapters by highly respected authors promises to be a most interesting read

• Puts soil health in the broader context of ecosystem services, conservation and climate change

• Summarises current research on soil structure and composition

• Reviews latest developments in understanding nutrient and other cycles in soil

Colorado soil health expert visits CASI's NRI field in Five Points!

August 13, 2018

Patrick O'Neill, certified crop and soil health advisor in the San Luis Valley in Colorado, took time from his busy travel schedule in California to stop by the NRI Project study field and talk with Jeff Mitchell on August 13th 2018.  He works in CO with a group of 15 farmers who are themselves trying to evaluate opportunities for improving soil function through the use of what they call “fungal-dominated compost” and cover crops in the largely potato, onion and grain food production systems that they have.  This is a region that is in many respects like California's San Joaquin Valley in terms of water availability and farmers there have had to constrain the actual amount of land that they now farm due to water allocation cutbacks.  Surprisingly perhaps and in contrast to what is commonly seen in the SJV, many farmers in the San Luis Valley are now using cover crops on lands that are fallow due to restrictions in irrigation water allocations as means to stabilize them and to keep some measure of soil biology active for when they rotate back to these fields for their cash crops.  We have invited Patrick to take part in future information exchanges with us in the new NRCS Conservation Innovation Grant and we look forward to very informative exchanges between him and folks in his region and the core group of farmers who are now working on this CIG effort.  Patrick took part in the “Health from the Soil Up – Bridging the Silos of Health and Agriculture” three-day conference that just concluded in Berkeley and Paicines, CA along with CASI's Jeff Mitchell.  This forum of folks from agriculture and the medical professions is now working together to look at creative ways to improve not only soil health, but also human health and opportunities for improving the overall health of the soil as well as the health of humans.  Much more will come from these sorts of collaborations and we welcome Patrick to being part of our work in California!
