Sustainable Irrigation

Abstract

Super-efficient irrigation is not new. It was first described more than two thousand years ago in China for people with too little land and too little water. Rediscovery of this information led to my work on super-efficient irrigation at remote desert sites more than thirty years ago. These systems benefit homeowners, gardeners, farmers, foresters, landscapers, and restorationist ecologists wherever water is scarce or costly. I hope it will also encourage further research and experimentation and the development of even better systems. 

 

The key to minimizing water use is getting water to the plant just as it is needed, with little or no loss of evaporation, runoff, or drainage lost into the deep soil. Getting water into the root zone quickly helps. These focused irrigation systems enable both water, soil amendments and fertilizer to be placed where they will benefit crops rather than weeds. Many new systems also reduce water use dramatically — by half or as much as 90%.
