Beautiful Agriculture With Salty Water
Normally it is not possible: irrigate with salty water. But a farm in Netherlands has managed to grow healthy and tasty vegetables in soil irrigated with salt water. Watch the video.
Salinization is reducing the world’s irrigated lands by 1 to 2 percent annually, according to the U.N.’s Food and Agriculture Organization.
In the Netherlands the first pilot with saline water was successful. At first the used saline water to kill some of a lot of different plants in order to identify which ones are able to thrive. Than they divided a farm into eight plots covered with a network of irrigation pipes.
Separate pipes bring fresh water and sea water to a distribution center where a computer-controlled system mixes irrigation water with eight different degrees of salinity.
The results were that they were able to harvest vegetables from most of the test plots. Although the plants were smaller than normal, they contain more sugar and salt, so they taste better.
The farm managed to grow carrots, cabbage, onions and beetroot, but potatoes proved to be the most tolerant to saline water. Four varieties of salt-tolerant potatoes recently were shipped to Pakistan where thousands of hectares of land damaged by salinization are being prepared for testing the Dutch potatoes.
