Hydroponic cultivation was planted by utilizing the water without the use of the land with emphasis on the fulfillment of the needs of nutrients for the plants. Need hydroponic water at less than the water needs in cultivation with soil. Hydroponics use water more efficiently, so the match is applied to areas that have limited water supply.
In the study of language, derived from the word hydroponics hydro meaning water and ponos meaning labor. So, hydroponics has the sense of freely farming techniques with emphasis on fulfilling the needs of nutrients for the plants, or in the sense of everyday farming without soil. From this sense looks that the emergence of cultivation in hydroponics is prefaced by the increasing attention to the importance of human need fertilizer for plants.
Wherever the growth of a plant will still be able to grow well in nutrition (nutrient) always required would be sure. In this context the function of soil is to buffer the plant and the water is the solvent-free nutrients, to then be absorbed by plants. It is this mindset that eventually gave birth to cultivation by hydroponics, where the emphasis is the fulfillment of a need of nutrients.
At first, the activity of cultivating land plants without soil are written on the book Sylva Sylvarum by Francis Bacon is made in the year 1627, printed a year after his death. Cultivation techniques on water became a popular research after that. In 1699, John Woodward published his water cultivation experiments with spearmint. He found that plants in water sources that are less pure grew better than plants with purified water.
In the year 1842 has compiled a list of nine elements believed to be essential to plant growth, and the discovery of the botanist Julius von Sachs Germany and Wilhelm Knop, in the years 1859-1865, triggering the development of techniques of cultivation without soil. [1] land plant growth without soil with a solution that emphasizes on fulfillment of mineral nutrients for the plant. It quickly became the standard of research and learning techniques, and are still used today. Now, Solution culture is considered a type of Hydroponic growing media without an inert growing medium, which is not a nutrient.
In 1929, William Frederick Gericke of the University of California at Berkeley began publicly promoting of culture Solution used to produce agricultural crops. At first he called it by the term aquaculture (or in Indonesia called aquaculture), but later learned of aquaculture has been applied to the cultivation of aquatic animals. Gericke created a sensation by growing tomatoes that extends as high as twenty-five feet, in the backyard of his house with a solution of mineral nutrients in addition to the ground. Based on the analogy with the term ancient Greece on aquaculture, γεωπονικά, the science of cultivating the Earth, Gericke coined the term hydroponics in 1937 (although he insists that the term was suggested by WA Setchell, of the University of California) for the cultivation of plants in water (from the ancient Greece ὕδωρ, water; and πόνος, energy
Gericke, he reports on claims that hydroponics would revolutionize plant agriculture and trigger a large number of requests further information. The submission was rejected by the University party Gericke about using greenhouse dikampusnya for experiments because of scepticism people administration campus. and when the University tried to force him to reveal the first nutrition recipes developed in the House, he asked for a place to greenhouse and it's time to fix it using the appropriate research facilities. While he eventually provided a place for the greenhouse, the University commissioned about his and Arnon to reorder formula Gericke, in 1940, after leaving the post of academic in an unfavorable climate in politics, he published a book titled the Complete Guide to Soil less Gardening.
