What do I need to do if there isn't 60 liters of water available?
I know that solve logistical issues in desert areas is not easy, but the quantity compared to irrigation is really small:
1. Groasis Ecological Water Saving Technology: once in a life time 60 liters
2. Drip irrigation: eternally each day 15 liters
On this page find an Excel document with a comparison of costs between the Groasis Ecological Water Saving Technology and the drip irrigation technology.
