This article describes how hydroponic systems can be used to produce food in an area with little water and little fertile soil. The innovative approach is to make optimal use of space, by planting both in a horizontal and vertical direction. Hyproponics is the process of growing plants in sand, gravel, or liquid, with added nutrients but without soil.
The author discusses how soilless farming improves the yield as nutrients are directly supplied to the plants, and plants grow quicker. Also, less space and less labour is needed than in regular farming methods.
However, the environment of the plants needs to be tightly controlled, and setting up the system is expensive.  The article describes the working methods and pro and cons of the using this system.

We add this article to the library to spark ideas on innovations and different approaches to agriculture.
