New CASI video available on "Twenty years of no-tilled double-cropped cotton and wheat in Goodyear, AZ" at


For over twenty years, Ron, Robert, and Earl Rayner of Goodyear, AZ have been perfecting a very interesting and successful system of no-tilled double-cropped cotton and wheat at A Tumbling T Ranches in Goodyear, AZ.  Their motivations and techniques for this highly innovative system, as well as the many very interesting things that they've learned over the years about how best to implement the practices that they employ are now chronicled in a 41-minute video that is available at the You Tube link above.

The video captures quite a lot of very good innovation and also sheds light on many very important aspects of conservation agriculture including risk management, the overall value of reduced disturbance residue-preserving practices, along with things that the Rayners have learned over the years related to water use efficiency, soil function, and farm sustainability. 

Special thanks to Ron Rayner for taking the time to share the many years of dedicated effort in this video.

A shorter, revised version of the video will be available later this year following the 2017 cotton harvest.
