We should probably start with a little background information for those of you who may not be familiar with the term “extension” as applied in the fields of education and management of agriculture and natural resources.


From Wikipedia:

“Agricultural extension is a general term meaning the application of scientific research and new knowledge to agricultural practices through farmer education. The field of extension now encompasses a wider range of communication and learning activities organized for rural people by professionals from different disciplines, including agriculture, agricultural marketing, health, and business studies.”

“The Cooperative Extension Service, also known as the Extension Service of the USDA, is a non-formal educational program implemented in the United States designed to help people use research-based knowledge to improve their lives. The service is provided by the state's designated land-grant universities.”


From Washington State University Extension:

“A land-grant college or university is an institution that has been designated by its state legislature or Congress to receive the benefits of the Morrill Acts of 1862 and 1890. The original mission of these institutions, as set forth in the first Morrill Act, was to teach agriculture, military tactics, and the mechanic arts as well as classical studies so that members of the working classes could obtain a liberal, practical education.”

Land grant universities have a 3-pronged basic mission structure with different but overlapping duties: Teaching, Research, and Extension. Most of us probably understand the first two. Extension or outreach, however, involves those research and educational efforts accomplished by faculty assigned to (as described above) put knowledge into the hands of the people working on the land or in rural communities. This involves not only “professors” and state level subject area experts but additional professionals engaged at the local level. For example, Dr John Sibley Butler, a distinguished business professor at the University of Texas writes in his County Agent Model for Entrepreneurship:

The agricultural county agent model is perhaps the most successful technology transfer mechanism that the United States has developed. This agricultural model has transferred an enormous amount of agricultural research to the American farm. The return on investment is self-evident...”


Dr Butler also quotes Irving M. May Jr:

“In this organization the most important person was the county agent, who worked with people to

identify their problems, motivated them, made scientific information available to them, and then

helped them use the information. The county agent’s primary responsibility was teaching. His goal

was to help people to have a higher standard of living and a more enjoyable life.”

So to summarize, that is what we do here at the V Bar V Range program; we serve as an outreach arm of the land grant school in the state, The University of Arizona, to bring science to the rangeland and to the people who live and work there. In addition to the Rimrock Report, Range Rocks! and Blue Collar Plants, the V Bar V Range Program is involved in multiple extension projects around the state of Arizona. Some of these have been initiated out of the V Bar V and some we have collaborated on with other groups. Here is a sample of what we have been up to lately:

Steps visual BCS "Pocket" range and animal monitoring forms It is often a good idea to check the body condition of your herd whenever you are already out on the ranch. So it is worth carrying around a pocket notebook to record observations. Here is a double sided form you can use for those body condition score observations. On one side it has the basic...

This site is under construction; we will soon have a list of forms to download that will assist with such as cattle body condition scoring, grazing utilization, and precipitation monitoring. Please check back soon.
