Sea level is rising around the world, so there is more salt in fresh water on the farms near the sea. As a result farmers are not able to use fields close to the sea.

But a farmer in the Netherlands is now using a mixture of sea and fresh water to grow healthy and delicious vegetables. Marc Van Rijsselberghe started with an experiment. He put several kinds of plants in the mixture. He worked on the project with scientists from the Free University of Amsterdam. He cut a farm into eight areas. Then he watered them with different（混合物）mixtures of fresh water and sea water, and a computer program created water with eight levels of the mixture.

Mr. Van Rijsselberghe says he was able to harvest（丰收）vegetables from most of the eight test areas. He says the vegetables were smaller than those grown in fresh water. But he says they also have more sugar and salt, so they taste better.

The farmer grew carrots, cabbage, onions and beetroot. But he found that potatoes grew better than the other vegetables in the mixture of sea and fresh water. Mr. Van Rijsselberghe says four kinds of these potatoes were sent to Pakistan. Farmers in Pakistan will test the potatoes to see if they can be grown in those fields.
