CONTROLLED ENVIRONMENT AGRICULTURE AND HYDROPONICS

CONTROLLED ENVIRONMENT AGRICULTURE AND HYDROPONICS

CONTROLLED ENVIRONMENT AGRICULTURE- Also “Protected Agriculture”. Control of each the foundation region and aerial environmental factors (temperature, humidity, composition consisting of carbon dioxide across the leaves for photosynthesis and oxygen round roots and shoots for respiration, light, water, developing medium, and mineral vitamins) commonly in a greenhouse or definitely enclosed structure.

HYDROPONICS. A generation for developing flora (with out soil) the use of a entire nutrient solution (water + mineral nutrients) without or with using an combination medium (e.g. sand, gravel, perlite, rockwool, etc.) to offer mechanical aid for the roots.

THE PAST: Several hundred years B.C. – The Babylonians had placing water way of life gardens taken into consideration one of the seven wonders of the historic world. Several hundred years B.C. – Egyptian hieroglyphs inform of the humans developing flora in water way of life. Theophrastus (372-287 B.C.) – A Greek philosopher, executed experiments in crop vitamins.

During the first century A.D. – cucumbers have been grown low season for the Roman Emperor Tiberius the use of a “obvious rock” (probably mica) protected structure (first known use of Controlled Environment Agriculture (CEA)). 1200’s and 1300’s (as defined through the Venetian traveler, Marco Polo) - Floating gardens of the Chinese. 1400’s – The Aztecs, who settled close to Lake Tenochititlan (close to the web page of gift day Mexico City), created gardens on floating rafts called “chinampas”. NOTE: During the beyond four hundred years plant way of life strategies have been advanced to look at the mineral vitamins necessities of flora. These strategies, acknowledged as “water way of life”, have been the beginnings of what later became “hydroponics”.
