Can Vegetables Be Cultivated Without Earth?

Vegetables have always grown in the earth, but are there any other way to cultivate them? The answer is yes. Scien- tists have found out that they can grow without earth as long as they have the necessary conditions for growth. This means having the right nutrients, water, air, sun-shine, and the appropriate tem-perature. To do this, you can spread a layer of sand at the bottom of a big tray or a shallow wood box. Then you plant vegetable sprouts in it. Next, you pre- pare a solution with nutrients needed by the particular vegetables you have plant-d and use it to water them regularly. Not long afterwards you should get an abundant supply of fresh vegetables. In this way people are able to grow vegetables in areas where there is little clay.
