Sustainable Agriculture Links

On this page, we will link to information that might be helpful to OFRA members and friends. These sustainable agriculture links provide useful information, but may be from the perspective of anywhere in the world. In our Documents files and in our Forums, we will work to take the general sustainable agriculture information and identify what is working in Oklahoma. We look forward to working together with members and friends to test ideas and communicate our results!

Please note that OFRA doesn't endorse or receive any benefits from any companies or organizations to which we provide links. It can be challenging to find equipment that works for managed grazing systems, so we provide links to equipment that we've used or colleagues have used.  If you're aware of other equipment that works please send information and links to

Whole Farm Planning

If you manage an Oklahoma farm or ranch implementing one or more of these practices and would like to be linked here, please email your info to

Holistic Management

Regrarians Platform (based on Yeoman's Keyline Scale of Permanence)

OFRA Beef Check Sheet
This check sheet is designed to stimulate critical thinking in planning a farm on which primary land use is production of beef cattle. 



Permanent Fencing

Water Systems

HDPE Water System Part

(Check out How to Build a Mobile Cattle Water System For Your Pasture Rotation for an introduction to an HDPE livestock water system.)

We are aware of only two U.S. companies that sell fittings specifically for these HDPE livestock water systems. If you know of other sources, please email info and links to: ofra.exec.dir at   Thanks!

HDPE couplers (These allow connection of HDPE pipe without any fusion equipment - just a couple of wrenches gets the job done.)

American Grazing Lands - Couplers

Powerflex Fence - Couplers

Quick Coupler Valves and Risers (These allow you to quickly connect the HDPE system to a stock tank with a garden hose.)

When installing your first system, we recommend calling your fitting provider and making sure you're ordering the right sizes to fit your HDPE pipe and your Quick Coupler Valves. Both companies provide at least some support by phone.

It can save funds to purchase HDPE Pipe locally. You can find suppliers by googling "HDPE Pipe Manufacturers," going to their websites and searching for distributors near you, then calling them to find the best prices. HDPE Pipe is made for many different uses. We like the Pipe that is certified for "potable" aka "drinking" water use. (Just ask the distributor, and they should direct you to the correct pipe.)
