Over the course of twelve years and in cooperation with some of the brightest minds in turf science today Turfgrass Water Conservation Alliance (TWCA) has developed the protocols and technologies for turf evaluation that are now standard industry wide. The key for TWCA, in the quest to define drought tolerance in turfgrass, is open and clear channels for communication.
Turfgrass Water Conservation Alliance (TWCA) created the Irrigation Calculator (based on this calculator from Pennington) to help end-users predict the runtimes of their irrigation systems. Simple.
TWCA collaborated with a network of public and private researchers including Oregon State University, University of Washington, University of Arkansas, and NexGen Plant Science Center, on a series of multi-year inquiries to answer some basic questions about site specific conditions.
The Irrigation Calculator is simple. Click the greenness of your grass (fun fact: during development we called this the "lush level"). Know the irrigation rate and weekly frequency. Remember where you live. It's true, there are some curveballs in there; not everyone knows if they have TWCA Qualified turfgrasses, but generally, pretty spoon and June.
The calculator itself is an example of interdisciplinary cooperation on a public/private partnership resulting in an immediately useful tool.
Turfgrass Water Conservation Alliance (TWCA) relies on our cooperators to conduct trialing. We recognize that our work is only a small part of what you do on your farm and that tracking the details of the study is not something you want to worry about. We also know you want to talk about all the cool and interesting work you spend your time on and we certainly hope TWCA is on the list of things you want to discuss.
To make it easier to express the scope and scale of the TWCA trialing we have created this list of talking points about the trial(s) TWCA is currently running.
Predictability and reliability are essential for long term reliability. In an industry where development is, sometimes, years in realization, TWCA is providing a schedule for trialing. Released today, the trialing schedule is an important tool for Seed Producers and trialing cooperators alike.
