What is hydroponics?

June 11, 2013 There have been 0 comments

The term hydroponics came about in the USA in the early 1930's to describe the growing of plants with their roots suspended in water containing mineral nutrients. Derived from the Greek words for 'water' - hydro and 'to work' - ponos, hydroponics literally means 'working with water'. The term has however gradually become broadened to describe all forms of gardening without the use of soil.

The use of hydroponic’s in history dates back to the Hanging Gardens of Babylon. The Aztec Indians had a system of growing crops on wooden rafts in shallow water.

You can still see some of these floating gardens in and around Mexico City. Further developments in hydroponics did not start taking place in Europe until around the 1850’s when a German scientist, started using nutrient solutions to study the nutritional requirements of plants and was followed by Sachs in 1860 and Knop in 1861 who made studies of nutrient elements in water solutions. They were able to grow plants in nutrient solutions made up from mineral salts eliminating the need for soil.

Research on the nutritional requirements of plants continued through the 1870’s. By 1925 practical applications of hydroponics were being made in the greenhouse industry. The next decade was to see extensive development as researchers became aware of the potential of growing hydroponically. In 1930 Gericke produced the first commercial hydroponic unit in the USA. Later during World War II the American forces in the Pacific grew vegetable crops hydroponically for quality foods aboard the ships. The commercial use of hydroponics spread throughout the world but it was the development of the N.F.T. system by Dr Alan Cooper in the 1970's, along with improved nutritional formulations that made the hydroponic growing of a wide range of plants commercially viable. Since then automatic control systems have become available as well as digital testing equipment which has opened up the field of hydroponics to the home gardener.

Hydroponics has come a long way since the Aztecs. It has become an essential method of growing crops in areas of the World where water is precious and land useless for field growing. Water care and land care is now legislative in many countries in the World, so with well managed hydroponic crops we can keep producing high quality produce which is environmentally friendly and sustainable for the future in all areas of the world.
